That is impossible to avoid because energy a country demand proportional to surge in the number of residents, economic growth and addition of industrial sector. Domestic Oil and gas conventional reserves depleted naturally while production outcome from reservoir also depleted time to time. In the other hand, new reserve did not discover significantly to replace it all. Many people are investigating to looking for new alternative energy to answer the challenge. There are several option to solve energy fossil needed problem using Unconventional Hydrocarbon. There are four aspects to consider as a management reference in order that Unconventional Hydrocarbon business can work properly, divided to: 1. Legal aspect, 2. Environmental aspect, 3. Technical aspect and 4. Economy aspect. The economic aspect as the key to whether or not a project can be implemented or not in Oil and Gas business scheme, so do Unconventional Hydorcarbon business scheme.

This study focuses on the thermal maturity and hydrocarbon generation histories of the Silurian Dadaş shales, utilizing basin modeling approach. The Dadaş shales are organic-rich and contain mainly Type II kerogen, especially the basal layer contains up to 10 wt. %TOC and thus it is named as “hot shale”.

The data obtained from previous studies were used to calibrate basin model that has been established by using PetroMod software (Schlumberger). The calibrated model results suggest that Dadaş shales are in oil generation window and that the major episode for thermal maturation and hydrocarbon generation took place prior rot Alpine orogeny (uplift and erosion) The modeling results elucidate the burial history, maturity history, and hydrocarbon production history of the Silurian-aged Dadaş shales, as well as its hydrocarbon content in the area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dada%C5%9F%20formation" title="dadaş formation">dadaş formation</a>, <a href="https://publications.waset.org/abstracts/search?q=diyarbak%C4%B1r%20basin" title=" diyarbakır basin"> diyarbakır basin</a>, <a href="https://publications.waset.org/abstracts/search?q=silurian%20hot%20shale" title=" silurian hot shale"> silurian hot shale</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20hydrocarbon" title=" unconventional hydrocarbon"> unconventional hydrocarbon</a> </p> <a href="https://publications.waset.org/abstracts/189223/an-assesment-of-unconventional-hydrocarbon-potential-of-the-silurian-dadas-shales-in-diyarbakir-basin-turkiye" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">32</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">500</span> Defining Unconventional Hydrocarbon Parameter Using Shale Play Concept</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Ryacudu">Rudi Ryacudu</a>, <a href="https://publications.waset.org/abstracts/search?q=Edi%20Artono"> Edi Artono</a>, <a href="https://publications.waset.org/abstracts/search?q=Gema%20Wahyudi%20Purnama"> Gema Wahyudi Purnama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil and gas consumption in Indonesia is currently on the rise due to its nation economic improvement. Unfortunately, Indonesia’s domestic oil production cannot meet it’s own consumption and Indonesia has lost its status as Oil and Gas exporter. Even worse, our conventional oil and gas reserve is declining. Unwilling to give up, the government of Indonesia has taken measures to invite investors to invest in domestic oil and gas exploration to find new potential reserve and ultimately increase production. Yet, it has not bear any fruit. Indonesia has taken steps now to explore new unconventional oil and gas play including Shale Gas, Shale Oil and Tight Sands to increase domestic production. These new plays require definite parameters to differentiate each concept. The purpose of this paper is to provide ways in defining unconventional hydrocarbon reservoir parameters in Shale Gas, Shale Oil and Tight Sands. The parameters would serve as an initial baseline for users to perform analysis of unconventional hydrocarbon plays. Some of the on going concerns or question to be answered in regards to unconventional hydrocarbon plays includes: 1. The TOC number, 2. Has it been well “cooked” and become a hydrocarbon, 3. What are the permeability and the porosity values, 4. Does it need a stimulation, 5. Does it has pores, and 6. Does it have sufficient thickness. In contrast with the common oil and gas conventional play, Shale Play assumes that hydrocarbon is retained and trapped in area with very low permeability. In most places in Indonesia, hydrocarbon migrates from source rock to reservoir. From this case, we could derive a theory that Kitchen and Source Rock are located right below the reservoir. It is the starting point for user or engineer to construct basin definition in relation with the tectonic play and depositional environment. Shale Play concept requires definition of characteristic, description and reservoir identification to discover reservoir that is technically and economically possible to develop. These are the steps users and engineers has to do to perform Shale Play: a. Calculate TOC and perform mineralogy analysis using water saturation and porosity value. b. Reconstruct basin that accumulate hydrocarbon c. Brittlenes Index calculated form petrophysical and distributed based on seismic multi attributes d. Integrated natural fracture analysis e. Best location to place a well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconventional%20hydrocarbon" title="unconventional hydrocarbon">unconventional hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas" title=" shale gas"> shale gas</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20oil%20tight%20sand%20reservoir%20parameters" title=" shale oil tight sand reservoir parameters"> shale oil tight sand reservoir parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20play" title=" shale play"> shale play</a> </p> <a href="https://publications.waset.org/abstracts/12493/defining-unconventional-hydrocarbon-parameter-using-shale-play-concept" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12493.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">406</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">499</span> Thermal Maturity and Hydrocarbon Generation Histories of the Silurian Tannezuft Shale Formation, Ghadames Basin, Northwestern Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emir%20Borovac">Emir Borovac</a>, <a href="https://publications.waset.org/abstracts/search?q=Sedat%20I%CC%87nan"> Sedat İnan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Silurian Tannezuft Formation within the Ghadames Basin of Northwestern Libya, like other Silurian shales in North Africa and the Middle East, represents a significant prospect for unconventional hydrocarbon exploration. Unlike the more popular and extensively studied Sirt Basin, the Ghadames Basin remains underexplored, presenting untapped potential that warrants further investigation. This study focuses on the thermal maturity and hydrocarbon generation histories of the Tannezuft shales, utilizing calibrated basin modeling approaches. The Tannezuft shales are organic-rich and primarily contain Type II kerogen, especially in the basal layer, which contains up to 10 wt. % TOC, leading to its designation as ‘hot shale’. The research integrates geological, geochemical, and basin modeling data to elucidate the unconventional hydrocarbon potential of this formation, which is crucial given the global demand for energy and the need for new resources. By employing PetroMod software from Schlumberger, calibrated modeling results simulate hydrocarbon generation and migration within the Tannezuft shales. The findings suggest dual-phase hydrocarbon generation from the Lower Silurian Tannezuft source rock, related to deep burial prior to Hercynian orogeny and subsequent Alpine orogeny events. The Ghadames Basin's tectonic history, including major Hercynian and Alpine orogenies, has significantly influenced the generation, migration, and preservation of hydrocarbons, making the Ghadames Basin a promising area for further exploration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tanezzuft%20formation" title="tanezzuft formation">tanezzuft formation</a>, <a href="https://publications.waset.org/abstracts/search?q=ghadames%20basin" title=" ghadames basin"> ghadames basin</a>, <a href="https://publications.waset.org/abstracts/search?q=silurian%20hot%20shale" title=" silurian hot shale"> silurian hot shale</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20hydrocarbon" title=" unconventional hydrocarbon"> unconventional hydrocarbon</a> </p> <a href="https://publications.waset.org/abstracts/189237/thermal-maturity-and-hydrocarbon-generation-histories-of-the-silurian-tannezuft-shale-formation-ghadames-basin-northwestern-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">26</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">498</span> Microseismics: Application in Hydrocarbon Reservoir Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Kumar%20Singh">Rahul Kumar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Apurva%20Sharma"> Apurva Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilip%20Kumar%20Srivastava"> Dilip Kumar Srivastava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tilting of our interest towards unconventional exploitation of hydrocarbons has raised a serious concern to environmentalists. Emerging technologies like horizontal/multi-lateral drilling with subsequent hydraulic fracturing or fracking etc., for exploitation of different conventional/unconventional hydrocarbon reservoirs, are related to creating micro-level seismic events below the surface of the earth. Monitoring of these micro-level seismic events is not possible by the conventional methodology of the seismic method. So, to tackle this issue, a new technology that is microseismic is very much in discussions around the globe. Multiple researches are being carried out these days around the globe in order to prove microseismic as a new essential in the E & P industry, especially for unconventional reservoir management. Microseismic monitoring is now used for reservoir surveillance, and the best application is checking the integrity of the caprock and containment of fluid in it. In general, in whatever terms we want to use micro-seismic related events monitoring and understanding the effectiveness of stimulation, this technology offers a lot of value in terms of insight into the subsurface characteristics and processes, and this makes it really a good geophysical method to be used in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microseismic" title="microseismic">microseismic</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20fracturing%20or%20fracking" title=" hydraulic fracturing or fracking"> hydraulic fracturing or fracking</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20surveillance" title=" reservoir surveillance"> reservoir surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20hazards" title=" seismic hazards"> seismic hazards</a> </p> <a href="https://publications.waset.org/abstracts/140429/microseismics-application-in-hydrocarbon-reservoir-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140429.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">497</span> Geochemical Characterization for Identification of Hydrocarbon Generation: Implication of Unconventional Gas Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousif%20M.%20Makeen">Yousif M. Makeen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research will address the processes of geochemical characterization and hydrocarbon generation process occurring within hydrocarbon source and/or reservoir rocks. The geochemical characterization includes organic-inorganic associations that influence the storage capacity of unconventional hydrocarbon resources (e.g. shale gas) and the migration process of oil/gas of the petroleum source/reservoir rocks. Kerogen i.e. the precursor of petroleum, occurs in various forms and types, may either be oil-prone, gas-prone, or both. China has a number of petroleum-bearing sedimentary basins commonly associated with shale gas, oil sands, and oil shale. Taken Sichuan basin as a selected basin in this study, the Sichuan basin has recorded notable successful discoveries of shale gas especially in the marine shale reservoirs within the area. However, a notable discoveries of lacustrine shale in the North-Este Fuling area indicate the accumulation of shale gas within non-marine source rock. The objective of this study is to evaluate the hydrocarbon storage capacity, generation, and retention processes in the rock matrix of hydrocarbon source/reservoir rocks within the Sichuan basin using an advanced X-ray tomography 3D imaging computational technology, commonly referred to as Micro-CT, SEM (Scanning Electron Microscope), optical microscope as well as organic geochemical facilities (e.g. vitrinite reflectance and UV light). The preliminary results of this study show that the lacustrine shales under investigation are acting as both source and reservoir rocks, which are characterized by very fine grains and very low permeability and porosity. Three pore structures have also been characterized in the study in the lacustrine shales, including organic matter pores, interparticle pores and intraparticle pores using x-ray Computed Tomography (CT). The benefits of this study would be a more successful oil and gas exploration and higher recovery factor, thus having a direct economic impact on China and the surrounding region. Methodologies: SRA TOC/TPH or Rock-Eval technique will be used to determine the source rock richness (S1 and S2) and Tmax. TOC analysis will be carried out using a multi N/C 3100 analyzer. The SRA and TOC results were used in calculating other parameters such as hydrogen index (HI) and production index (PI). This analysis will indicate the quantity of the organic matter. Minimum TOC limits generally accepted as essential for a source-rock are 0.5% for shales and 0.2% for carbonates. Contributions: This research could solve issues related to oil potential, provide targets, and serve as a pathfinder to future exploration activity in the Sichuan basin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shale%20gas" title="shale gas">shale gas</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20resources" title=" unconventional resources"> unconventional resources</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20chemistry" title=" organic chemistry"> organic chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=Sichuan%20basin" title=" Sichuan basin"> Sichuan basin</a> </p> <a href="https://publications.waset.org/abstracts/186791/geochemical-characterization-for-identification-of-hydrocarbon-generation-implication-of-unconventional-gas-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186791.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">37</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">496</span> Characterization of the Pore System and Gas Storage Potential in Unconventional Reservoirs: A Case of Study of the Cretaceous la Luna Formation, Middle Magdalena Valley Basin, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Alberto%20R%C3%ADos-Reyes">Carlos Alberto Ríos-Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Efra%C3%ADn%20Casadiego-Quintero"> Efraín Casadiego-Quintero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a generalized workflow for mineralogy investigation of unconventional reservoirs using multi-scale imaging and pore-scale analyses. This workflow can be used for the integral evaluation of these resources. The Cretaceous La Luna Formation´s mudstones in the Middle Magdalena Valley Basin (Colombia) inherently show a heterogeneous pore system with organic and inorganic pores. For this reason, it is necessary to carry out the integration of high resolution 2D images of mapping by conventional petrography, scanning electron microscopy and quantitative evaluation of minerals by scanning electron microscopy to describe their organic and inorganic porosity to understand the transport mechanism through pores. The analyzed rocks show several pore types, including interparticle pores, organoporosity, intraparticle pores, intraparticle pores, and microchannels and/or microfractures. The existence of interconnected pores in pore system of these rocks promotes effective pathways for primary gas migration and storage space for residual hydrocarbons in mudstones, which is very useful in this type of gas reservoirs. It is crucial to understand not only the porous system of these rocks and their mineralogy but also to project the gas flow in order to design the appropriate strategies for the stimulation of unconventional reservoirs.

In order to determine the zones in which maximum volumes of hydrocarbons might have been generated and preserved as shale gas reservoirs, as well as to identify the most preferable well sites where largest gas accumulations are anticipated a number of task were accomplished. Evaluation of petrophysical properties and hydrocarbon saturation of the Miocene complex is based on laboratory measurements as well as interpretation of well-logs and archival data. The studies apply mercury porosimetry (MICP), micro CT and nuclear magnetic resonance imaging (using the Rock Core Analyzer). For prospective location (e.g. central part of Carpathian Foredeep – Brzesko-Wojnicz area) reprocessing and reinterpretation of detailed seismic survey data with the use of integrated geophysical investigations has been made. Construction of quantitative, structural and parametric models for selected areas of the Carpathian Foredeep is performed on the basis of integrated, detailed 3D computer models. Modeling are carried on with the Schlumberger’s Petrel software. Finally, prospective zones are spatially contoured in a form of regional 3D grid, which will be framework for generation modelling and comprehensive parametric mapping, allowing for spatial identification of the most prospective zones of unconventional gas accumulation in the Carpathian Foredeep. Preliminary results of research works indicate a potentially prospective area for occurrence of unconventional gas accumulations in the Polish part of Carpathian Foredeep. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autochthonous%20Miocene" title="autochthonous Miocene">autochthonous Miocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Carpathian%20foredeep" title=" Carpathian foredeep"> Carpathian foredeep</a>, <a href="https://publications.waset.org/abstracts/search?q=Poland" title=" Poland"> Poland</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas" title=" shale gas"> shale gas</a> </p> <a href="https://publications.waset.org/abstracts/62319/exploration-of-hydrocarbon-unconventional-accumulations-in-the-argillaceous-formation-of-the-autochthonous-miocene-succession-in-the-carpathian-foredeep" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62319.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">494</span> Research on Tight Sandstone Oil Accumulation Process of the Third Member of Shahejie Formation in Dongpu Depression, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hui%20Li">Hui Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiongqi%20Pang"> Xiongqi Pang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, tight oil has become a hot spot for unconventional oil and gas exploration and development in the world. Dongpu Depression is a typical hydrocarbon-rich basin in the southwest of Bohai Bay Basin, in which tight sandstone oil and gas have been discovered in deep reservoirs, most of which are buried more than 3500m. The distribution and development characteristics of deep tight sandstone reservoirs need to be studied. The main source rocks in study area are dark mudstone and shale of the middle and lower third sub-member of Shahejie Formation. Total Organic Carbon (TOC) content of source rock is between 0.08-11.54%, generally higher than 0.6% and the value of S1+S2 is between 0.04–72.93 mg/g, generally higher than 2 mg/g. It can be evaluated as middle to fine level overall. The kerogen type of organic matter is predominantly typeⅡ1 andⅡ2. Vitrinite reflectance (Ro) is mostly greater than 0.6% indicating that the source rock entered the hydrocarbon generation threshold. The physical property of reservoir was poor, the most reservoir has a porosity lower than 12% and a permeability of less than 1×10⁻³μm. The rocks in this area showed great heterogeneity, some areas developed desserts with high porosity and permeability. According to SEM, thin section image, inclusion test and so on, the reservoir was affected by compaction and cementation during early diagenesis stage (44-31Ma). The diagenesis caused the tight reservoir in Huzhuangji, Pucheng, Weicheng Area while the porosity in Machang, Qiaokou, Wenliu Area was still over 12%. In the process of middle diagenesis phase stage A (31-17Ma), the reservoir porosity in Machang, Pucheng, Huzhuangji Area increased due to dissolution; after that the oil generation window of source rock was achieved for the first phase hydrocarbon charging (31-23Ma), formed the conventional oil deposition in Machang, Qiaokou, Wenliu, Huzhuangji Area and unconventional tight reservoir in Pucheng, Weicheng Area. Then came to stage B of middle diagenesis phase (17-7Ma), in this stage, the porosity of reservoir continued to decrease after the dissolution and led to a situation that the reservoirs were generally compacted. And since then, the second hydrocarbon filling has been processing since 7Ma. Most of the pools charged and formed in this procedure are tight sandstone oil reservoir. In conclusion, tight sandstone oil was formed in two patterns in Dongpu Depression, which could be concluded as ‘density fist then accumulation’ pattern and ‘accumulation fist next density’ pattern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accumulation%20process" title="accumulation process">accumulation process</a>, <a href="https://publications.waset.org/abstracts/search?q=diagenesis" title=" diagenesis"> diagenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=dongpu%20depression" title=" dongpu depression"> dongpu depression</a>, <a href="https://publications.waset.org/abstracts/search?q=tight%20sandstone%20oil" title=" tight sandstone oil"> tight sandstone oil</a> </p> <a href="https://publications.waset.org/abstracts/95245/research-on-tight-sandstone-oil-accumulation-process-of-the-third-member-of-shahejie-formation-in-dongpu-depression-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">493</span> Mature Field Rejuvenation Using Hydraulic Fracturing: A Case Study of Tight Mature Oilfield with Reveal Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Gharavi">Amir Gharavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hassan"> Mohamed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Shah"> Amjad Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main characteristics of unconventional reservoirs include low-to ultra low permeability and low-to-moderate porosity. As a result, hydrocarbon production from these reservoirs requires different extraction technologies than from conventional resources. An unconventional reservoir must be stimulated to produce hydrocarbons at an acceptable flow rate to recover commercial quantities of hydrocarbons. Permeability for unconventional reservoirs is mostly below 0.1 mD, and reservoirs with permeability above 0.1 mD are generally considered to be conventional. The hydrocarbon held in these formations naturally will not move towards producing wells at economic rates without aid from hydraulic fracturing which is the only technique to assess these tight reservoir productions. Horizontal well with multi-stage fracking is the key technique to maximize stimulated reservoir volume and achieve commercial production. The main objective of this research paper is to investigate development options for a tight mature oilfield. This includes multistage hydraulic fracturing and spacing by building of reservoir models in the Reveal simulator to model potential development options based on sidetracking the existing vertical well. To simulate potential options, reservoir models have been built in the Reveal. An existing Petrel geological model was used to build the static parts of these models. A FBHP limit of 40bars was assumed to take into account pump operating limits and to maintain the reservoir pressure above the bubble point. 300m, 600m and 900m lateral length wells were modelled, in conjunction with 4, 6 and 8 stages of fracs. Simulation results indicate that higher initial recoveries and peak oil rates are obtained with longer well lengths and also with more fracs and spacing. For a 25year forecast, the ultimate recovery ranging from 0.4% to 2.56% for 300m and 1000m laterals respectively. The 900m lateral with 8 fracs 100m spacing gave the highest peak rate of 120m3/day, with the 600m and 300m cases giving initial peak rates of 110m3/day. Similarly, recovery factor for the 900m lateral with 8 fracs and 100m spacing was the highest at 2.65% after 25 years. The corresponding values for the 300m and 600m laterals were 2.37% and 2.42%. Therefore, the study suggests that longer laterals with 8 fracs and 100m spacing provided the optimal recovery, and this design is recommended as the basis for further study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconventional" title="unconventional">unconventional</a>, <a href="https://publications.waset.org/abstracts/search?q=resource" title=" resource"> resource</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic" title=" hydraulic"> hydraulic</a>, <a href="https://publications.waset.org/abstracts/search?q=fracturing" title=" fracturing"> fracturing</a> </p> <a href="https://publications.waset.org/abstracts/66977/mature-field-rejuvenation-using-hydraulic-fracturing-a-case-study-of-tight-mature-oilfield-with-reveal-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">492</span> Identification of Shocks from Unconventional Monetary Policy Measures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarita%20Grushanina">Margarita Grushanina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> After several prominent central banks including European Central Bank (ECB), Federal Reserve System (Fed), Bank of Japan and Bank of England employed unconventional monetary policies in the aftermath of the financial crisis of 2008-2009 the problem of identification of the effects from such policies became of great interest. One of the main difficulties in identification of shocks from unconventional monetary policy measures in structural VAR analysis is that they often are anticipated, which leads to a non-fundamental MA representation of the VAR model. Moreover, the unconventional monetary policy actions may indirectly transmit to markets information about the future stance of the interest rate, which raises a question of the plausibility of the assumption of orthogonality between shocks from unconventional and conventional policy measures. This paper offers a method of identification that takes into account the abovementioned issues. The author uses factor-augmented VARs to increase the information set and identification through heteroskedasticity of error terms and rank restrictions on the errors’ second moments’ matrix to deal with the cross-correlation of the structural shocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factor-augmented%20VARs" title="factor-augmented VARs">factor-augmented VARs</a>, <a href="https://publications.waset.org/abstracts/search?q=identification%20through%20heteroskedasticity" title=" identification through heteroskedasticity"> identification through heteroskedasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=monetary%20policy" title=" monetary policy"> monetary policy</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20VARs" title=" structural VARs"> structural VARs</a> </p> <a href="https://publications.waset.org/abstracts/81250/identification-of-shocks-from-unconventional-monetary-policy-measures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81250.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">348</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">491</span> Applying Big Data Analysis to Efficiently Exploit the Vast Unconventional Tight Oil Reserves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shengnan%20Chen">Shengnan Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuhua%20Wang"> Shuhua Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Successful production of hydrocarbon from unconventional tight oil reserves has changed the energy landscape in North America. The oil contained within these reservoirs typically will not flow to the wellbore at economic rates without assistance from advanced horizontal well and multi-stage hydraulic fracturing. Efficient and economic development of these reserves is a priority of society, government, and industry, especially under the current low oil prices. Meanwhile, society needs technological and process innovations to enhance oil recovery while concurrently reducing environmental impacts. Recently, big data analysis and artificial intelligence become very popular, developing data-driven insights for better designs and decisions in various engineering disciplines. However, the application of data mining in petroleum engineering is still in its infancy. The objective of this research aims to apply intelligent data analysis and data-driven models to exploit unconventional oil reserves both efficiently and economically. More specifically, a comprehensive database including the reservoir geological data, reservoir geophysical data, well completion data and production data for thousands of wells is firstly established to discover the valuable insights and knowledge related to tight oil reserves development. Several data analysis methods are introduced to analysis such a huge dataset. For example, K-means clustering is used to partition all observations into clusters; principle component analysis is applied to emphasize the variation and bring out strong patterns in the dataset, making the big data easy to explore and visualize; exploratory factor analysis (EFA) is used to identify the complex interrelationships between well completion data and well production data. Different data mining techniques, such as artificial neural network, fuzzy logic, and machine learning technique are then summarized, and appropriate ones are selected to analyze the database based on the prediction accuracy, model robustness, and reproducibility. Advanced knowledge and patterned are finally recognized and integrated into a modified self-adaptive differential evolution optimization workflow to enhance the oil recovery and maximize the net present value (NPV) of the unconventional oil resources. This research will advance the knowledge in the development of unconventional oil reserves and bridge the gap between the big data and performance optimizations in these formations. The newly developed data-driven optimization workflow is a powerful approach to guide field operation, which leads to better designs, higher oil recovery and economic return of future wells in the unconventional oil reserves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=enhance%20oil%20recovery" title=" enhance oil recovery"> enhance oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20oil%20reserves" title=" unconventional oil reserves"> unconventional oil reserves</a> </p> <a href="https://publications.waset.org/abstracts/67491/applying-big-data-analysis-to-efficiently-exploit-the-vast-unconventional-tight-oil-reserves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67491.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">490</span> Application of Unconventional Materials for ‘Statement Jewellery’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaleni%20Bajpai">Shaleni Bajpai</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Niveditha"> V.

The secondary fuel and syngas was fed into the furnace with two purposes- partial replacement of main fuel and reburning of NOx. Some portion of syngas was fed into the flame zone to partially replace the heavy oil, while the other portion was fed into the furnace downstream to reduce NOx generation. The numerical prediction was verified by comparing it with the experimental results. Syngas of KITECH’s experiment, assumed to be produced from biomass, had very low calorific value and contained 3% hydrocarbon. This study investigated the precise behavior of NOx generation and NOx reduction as well as thermo-fluidic characteristics inside the furnace, which was unavailable with experiment. In addition to 3% hydrocarbon syngas, 5%, and 7% hydrocarbon syngas were numerically tested as reburning fuels to analyze the effect of hydrocarbon proportion to NOx reduction. The prediction showed that the 3% hydrocarbon syngas is as much effective as 7% hydrocarbon syngas in reducing NOx. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=syngas" title="syngas">syngas</a>, <a href="https://publications.waset.org/abstracts/search?q=reburning" title=" reburning"> reburning</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20oil" title=" heavy oil"> heavy oil</a>, <a href="https://publications.waset.org/abstracts/search?q=furnace" title=" furnace"> furnace</a> </p> <a href="https://publications.waset.org/abstracts/23342/reburning-characteristics-of-biomass-syngas-in-a-pilot-scale-heavy-oil-furnace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">488</span> Characterization of Biosurfactant during Crude Oil Biodegradation Employing Pseudomonas sp.

Microorganisms with high oil-degrading performance are essential for bioremediation of petroleum hydrocarbon. In this investigation, an effective biosurfactant producer and hydrocarbon degrading bacterial strain, Pseudomonas sp.PG1 (identified by 16s rDNA sequencing) was isolated from hydrocarbon contaminated garage soil of Pathsala, Assam, India, using crude oil enrichment technique. The growth parameters such as pH and temperature were optimized for the strain and upto 81.8% degradation of total petroleum hydrocarbon (TPH) has been achieved after 5 weeks when grown in mineral salt media (MSM) containing 2% (w/v) crude oil as the carbon source. The biosurfactant production during the course of hydrocarbon degradation was monitored by surface tension measurement and emulsification activity. The produced biosurfactant had the ability to decrease the surface tension of MSM from 72 mN/m to 29.6 mN/m, with the critical micelle concentration (CMC)of 56 mg/L. The biosurfactant exhibited 100% emulsification activity on crude oil. FTIR spectroscopy and LCMS-MS analysis of the purified biosurfactant revealed that the biosurfactant is Rhamnolipidic in nature with several rhamnolipid congeners. Gas Chromatography-Mass spectroscopy (GC-MS) analysis clearly demonstrated that the strain PG1 efficiently degrade different hydrocarbon fractions of the crude oil. The study suggeststhat application of the biosurfactant producing strain PG1 as an appropriate candidate for bioremediation of crude oil contaminants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=petroleum%20hydrocarbon" title="petroleum hydrocarbon">petroleum hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contamination" title=" hydrocarbon contamination"> hydrocarbon contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title=" bioremediation"> bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=biosurfactant" title=" biosurfactant"> biosurfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=rhamnolipid" title=" rhamnolipid"> rhamnolipid</a> </p> <a href="https://publications.waset.org/abstracts/27073/characterization-of-biosurfactant-during-crude-oil-biodegradation-employing-pseudomonas-sp-pg1-a-strain-isolated-from-garage-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27073.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">487</span> Hydrocarbon New Business Opportunities in the Bida Basin of Central Nigeria: Prospect and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20G.%20Obaje">N.

Geological mapping was used to delineate the geological boundaries between the formations which is a significant initial criterion in evaluating hydrocarbon prospectivity. Processed and interpreted geophysical aeromagnetic data over the basin juxtaposed against the geological map has led to ranking of the prospectivity as less prospective, prospective and more prospective. The prospective and more prospective areas constitute new hydrocarbon business opportunities in the basin. The more prospective areas are at Pattishabakolo near Bida and at Kandi near Gulu. Prospective areas cover Badegi, Lemu, Duba, Kutigi, Auna, Mashegu and Mokwa.

Most remote sensing methods adopt techniques for hydrocarbon identification to achieve detection in order to model an appropriate cleanup program. Identification on optical sensors does not only allow for detection but also for characterization and quantification. Until recently, in optical remote sensing, quantification and characterization are only potentially possible using high-resolution laboratory and airborne imaging spectrometers (hyperspectral data). Unlike multispectral, hyperspectral data are not freely available, as this data category is mainly obtained via airborne survey at present. In this research, two (2) operational high-resolution multispectral satellites (WorldView-3 and Sentinel-2) are theoretically assessed for their suitability for hydrocarbon characterization, using the hydrocarbon spectral slope model (HYSS). This method utilized the two most persistent hydrocarbon diagnostic/absorption features at 1.73 µm and 2.30 µm for hydrocarbon mapping on multispectral data. In this research, spectra measurement of seven (7) different hydrocarbon oils (crude and refined oil) taken on ten (10) different substrates with the use of laboratory ASD Fieldspec were convolved to Sentinel-2 and WorldView-3 resolution, using their full width half maximum (FWHM) parameter. The resulting hydrocarbon slope values obtained from the studied samples enable clear qualitative discrimination of most hydrocarbons, despite the presence of different background substrates, particularly on WorldView-3. Due to close conformity of central wavelengths and narrow bandwidths to key hydrocarbon bands used in HYSS, the statistical significance for qualitative analysis on WorldView-3 sensors for all studied hydrocarbon oil returned with 95% confidence level (P-value ˂ 0.01), except for Diesel. Using multifactor analysis of variance (MANOVA), the discriminating power of HYSS is statistically significant for most hydrocarbon-substrate combinations on Sentinel-2 and WorldView-3 FWHM, revealing the potential of these two operational multispectral sensors as rapid response tools for hydrocarbon mapping. One notable exception is highly transmissive hydrocarbons on Sentinel-2 data due to the non-conformity of spectral bands with key hydrocarbon absorptions and the relatively coarse bandwidth (> 100 nm). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon" title="hydrocarbon">hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20spill" title=" oil spill"> oil spill</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperspectral" title=" hyperspectral"> hyperspectral</a>, <a href="https://publications.waset.org/abstracts/search?q=multispectral" title=" multispectral"> multispectral</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon-substrate%20combination" title=" hydrocarbon-substrate combination"> hydrocarbon-substrate combination</a>, <a href="https://publications.waset.org/abstracts/search?q=Sentinel-2" title=" Sentinel-2"> Sentinel-2</a>, <a href="https://publications.waset.org/abstracts/search?q=WorldView-3" title=" WorldView-3"> WorldView-3</a> </p> <a href="https://publications.waset.org/abstracts/139188/assessing-the-theoretical-suitability-of-sentinel-2-and-worldview-3-data-for-hydrocarbon-mapping-of-spill-events-using-hydrocarbon-spectral-slope-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139188.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">485</span> Technology Valuation of Unconventional Gas R&D Project Using Real Option Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young%20Yoon">Young Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinsoo%20Kim"> Jinsoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adoption of information and communication technologies (ICT) in all industry is growing under industry 4.0. Many oil companies also are increasingly adopting ICT to improve the efficiency of existing operations, take more accurate and quicker decision making and reduce entire cost by optimization. It is true that ICT is playing an important role in the process of unconventional oil and gas development and companies must take advantage of ICT to gain competitive advantage. In this study, real option approach has been applied to Unconventional gas R&D project to evaluate ICT of them. Many unconventional gas reserves such as shale gas and coal-bed methane(CBM) has developed due to technological improvement and high energy price. There are many uncertainties in unconventional development on the three stage(Exploration, Development, Production). The traditional quantitative benefits-cost method, such as net present value(NPV) is not sufficient for capturing ICT value. We attempted to evaluate the ICT valuation by applying the compound option model; the model is applied to real CBM project case, showing how it consider uncertainties. Variables are treated as uncertain and a Monte Carlo simulation is performed to consider variables effect.

Our experimental work in the Ouargla basin which aims to study the Spirulina productivity cultivated under greenhouse in unconventional waters enriched and non-enriched, drainage and wastewater treated were used in the experiment. For this, we proceeded to measure the biomass concentration by the DO625. The high biomass concentration and productivity amount were in treated wastewater enriched with 2.49±1.09 and 0.12±0.57 respectively, while The high amount in drainage water were in medium enriched with 2.19 ± 0.85 g/l and 0.08±0.52 g/l/d respectively. In spite of the enrichment and the good productivity of these waters, the chemical and microbiological qualities remain to study for a better valuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algeria" title="Algeria">Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouargla" title=" Ouargla"> Ouargla</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=Spirulina" title=" Spirulina"> Spirulina</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20water" title=" unconventional water"> unconventional water</a> </p> <a href="https://publications.waset.org/abstracts/8997/impact-of-unconventional-waters-on-spirulina-production-under-greenhouse-condition-in-ouargla" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8997.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">483</span> Analysis of Production Forecasting in Unconventional Gas Resources Development Using Machine Learning and Data-Driven Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dongkwon%20Han">Dongkwon Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangho%20Kim"> Sangho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kwon"> Sunil Kwon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unconventional gas resources have dramatically changed the future energy landscape. Unlike conventional gas resources, the key challenges in unconventional gas have been the requirement that applies to advanced approaches for production forecasting due to uncertainty and complexity of fluid flow. In this study, artificial neural network (ANN) model which integrates machine learning and data-driven approach was developed to predict productivity in shale gas. The database of 129 wells of Eagle Ford shale basin used for testing and training of the ANN model. The Input data related to hydraulic fracturing, well completion and productivity of shale gas were selected and the output data is a cumulative production. The performance of the ANN using all data sets, clustering and variables importance (VI) models were compared in the mean absolute percentage error (MAPE). ANN model using all data sets, clustering, and VI were obtained as 44.22%, 10.08% (cluster 1), 5.26% (cluster 2), 6.35%(cluster 3), and 32.23% (ANN VI), 23.19% (SVM VI), respectively. The results showed that the pre-trained ANN model provides more accurate results than the ANN model using all data sets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconventional%20gas" title="unconventional gas">unconventional gas</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=variables%20importance" title=" variables importance"> variables importance</a> </p> <a href="https://publications.waset.org/abstracts/73869/analysis-of-production-forecasting-in-unconventional-gas-resources-development-using-machine-learning-and-data-driven-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73869.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">482</span> Microfacies and Sedimentary Environment of Potentially Hydrocarbon-Bearing Ordovician and Silurian Deposits of Selected Boreholes in the Baltic Syneclise (NE Poland)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Sobczak">Katarzyna Sobczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last few years extensive research on the Lower Palaeozic of the Baltic region has been carried out, associated with growing interest in the unconventional hydrocarbon resources of the area. The present study contributes to this investigation by providing relevant microfacies analysis of Ordovician and Silurian carbonate and clastic deposits of the Polish part of the Baltic Syneclise, using data from the Kętrzyn IG-1, Henrykowo 1 and Babiak 1 boreholes. The analytical data, encompassing sedimentological, palaeontological, and petrographic indicators enables the interpretation of the sedimentary environments and their control factors. The main microfacies types distinguished within the studied interval are: bioclastic wackestone, bioclastic packstone, carbonate-rich mudstone, marlstone, nodular limestone and bituminous claystone. The Ordovician is represented by redeposited carbonate rocks formed in a relatively high-energy environment (middle shelf setting). The Upper Ordovician-Lower Silurian rocks of the studied basin represent sedimentary succession formed during a distinctive marine transgression. Considering the sedimentological and petrological data from the Silurian, a low-energy sedimentary environment (offshore setting) with intermittent high-energy events (tempestites) can be inferred for the sedimentary basin of NE Poland. Slow sedimentation of carbonate ooze and fine-grained siliciclastic rocks, formed under oxygen-deficient conditions of the seabed, favoured organic matter preservation. The presence of the storm beds suggests an episodic nature of seabed oxygenation. A significant part of the analysed depositional successions shows characteristics indicative of deposition from gravity flows, but lacks evidence of its turbidity origins. There is, however, evidence for storms acting as a mechanism of flow activation. The discussed Ordovician-Silurian transition of depositional environments in the Baltic area fits well to the global environmental changes encompassing the Upper Ordovician and the Lower Silurian. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baltic%20Syneclise" title="Baltic Syneclise">Baltic Syneclise</a>, <a href="https://publications.waset.org/abstracts/search?q=microfacies%20analysis" title=" microfacies analysis"> microfacies analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ordovician" title=" Ordovician"> Ordovician</a>, <a href="https://publications.waset.org/abstracts/search?q=Silurian" title=" Silurian"> Silurian</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20hydrocarbons" title=" unconventional hydrocarbons"> unconventional hydrocarbons</a> </p> <a href="https://publications.waset.org/abstracts/23705/microfacies-and-sedimentary-environment-of-potentially-hydrocarbon-bearing-ordovician-and-silurian-deposits-of-selected-boreholes-in-the-baltic-syneclise-ne-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">433</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">481</span> Simulation Study of Asphaltene Deposition and Solubility of CO2 in the Brine during Cyclic CO2 Injection Process in Unconventional Tight Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashid%20S.%20Mohammad">Rashid S.

Cyclic CO<sub>2</sub> injection is an enhanced oil recovery process consisting of injection, shut-in, and production. The study of cyclic CO<sub>2</sub> injection and hydrocarbon recovery in ultra-low permeability reservoirs is mainly a function of rock, fluid, and operational parameters. CMG-GEM was used to study several design parameters of cyclic CO<sub>2</sub> injection process to distinguish the parameters with maximum effect on the oil recovery and to comprehend the behavior of cyclic CO<sub>2</sub> injection in tight reservoir. On the other hand, permeability reduction induced by asphaltene precipitation is one of the major issues in the oil industry due to its plugging onto the porous media which reduces the oil productivity. In addition to asphaltene deposition, solubility of CO<sub>2</sub> in the aquifer is one of the safest and permanent trapping techniques when considering CO<sub>2</sub> storage mechanisms in geological formations. However, the effects of the above uncertain parameters on the process of CO<sub>2</sub> enhanced oil recovery have not been understood systematically. Hence, it is absolutely necessary to study the most significant parameters which dominate the process. The main objective of this study is to improve techniques for designing cyclic CO<sub>2</sub> injection process while considering the effects of asphaltene deposition and solubility of CO<sub>2</sub> in the brine in order to prevent asphaltene precipitation, minimize CO<sub>2</sub> emission, optimize cyclic CO<sub>2</sub> injection, and maximize oil production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tight%20reservoirs" title="tight reservoirs">tight reservoirs</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20O%E2%82%82%20injection" title=" cyclic O₂ injection"> cyclic O₂ injection</a>, <a href="https://publications.waset.org/abstracts/search?q=asphaltene" title=" asphaltene"> asphaltene</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20simulation" title=" reservoir simulation"> reservoir simulation</a> </p> <a href="https://publications.waset.org/abstracts/72427/simulation-study-of-asphaltene-deposition-and-solubility-of-co2-in-the-brine-during-cyclic-co2-injection-process-in-unconventional-tight-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72427.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">480</span> Analyzing the Oil and Gas Exploration Opportunities in Poland: Five Prospective Areas Selected and Dedicated to the Tender</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krystian%20W%C3%B3jcik">Krystian Wójcik</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Wr%C3%B3blewska"> Sara Wróblewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20%C5%81ojek"> Marcin Łojek</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Sobie%C5%84"> Katarzyna Sobień</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polish Geological Survey selected five of the most prospective areas for oil and gas exploration in Poland.

Directorate General Petroleum Concessions (DGPC) has taken the lead on the assessment of indigenous unconventional oil and gas resources, which has resulted in a ‘Shale Oil/Gas Resource Assessment Study’ conducted with the help of USAID. This was critically required in the energy-starved Pakistan, where the gap between indigenous oil & gas production and demand continues to widen for a long time. Exploration & exploitation of indigenous unconventional resources of Pakistan have become vital to meet our energy demand and reduction of oil and gas import bill of the country. This study has attempted to bridge a critical gap in geological information about the potential of shale gas & oil in Pakistan in the four formations, i.e., Sembar, Lower Goru, Ranikot and Ghazij in the Middle and Lower Indus Basins, which were selected for the study as for resource assessment for shale gas & oil. The primary objective of the study was to estimate and establish shale oil/gas resource assessment of the study area by carrying out extensive geological analysis of exploration, appraisal and development wells drilled in the Middle and Lower Indus Basins, along with identification of fairway(s) and sweet spots in the study area. The Study covers the Lower parts of the Middle Indus basins located in Sindh, southern Punjab & eastern parts of the Baluchistan provinces, with a total sedimentary area of 271,795 km2. Initially, 1611 wells were reviewed, including 1324 wells drilled through different shale formations. Based on the availability of required technical data, a detailed petrophysical analysis of 124 wells (21 Confidential & 103 in the public domain) has been conducted for the shale gas/oil potential of the above-referred formations. The core & cuttings samples of 32 wells and 33 geochemical reports of prospective Shale Formations were available, which were analyzed to calibrate the results of petrophysical analysis with petrographic/ laboratory analyses to increase the credibility of the Shale Gas Resource assessment. This study has identified the most prospective intervals, mainly in Sembar and Lower Goru Formations, for shale gas/oil exploration in the Middle and Lower Indus Basins of Pakistan. The study recommends seven (07) sweet spots for undertaking pilot projects, which will enable to evaluate of the actual production capability and production sustainability of shale oil/gas reservoirs of Pakistan for formulating future strategies to explore and exploit shale/oil resources of Pakistan including fiscal incentives required for developing shale oil/gas resources of Pakistan. Some E&P Companies are being persuaded to make a consortium for undertaking pilot projects that have shown their willingness to participate in the pilot project at appropriate times. The location for undertaking the pilot project has been finalized as a result of a series of technical sessions by geoscientists of the potential consortium members after the review and evaluation of available studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conventional%20resources" title="conventional resources">conventional resources</a>, <a href="https://publications.waset.org/abstracts/search?q=petrographic%20analysis" title=" petrographic analysis"> petrographic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=petrophysical%20analysis" title=" petrophysical analysis"> petrophysical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20resources" title=" unconventional resources"> unconventional resources</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas%20%26%20oil" title=" shale gas & oil"> shale gas & oil</a>, <a href="https://publications.waset.org/abstracts/search?q=sweet%20spots" title=" sweet spots"> sweet spots</a> </p> <a href="https://publications.waset.org/abstracts/185834/shale-gas-and-oil-resource-assessment-in-middle-and-lower-indus-basin-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185834.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">48</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">478</span> Aspects of Environmental Sustainability in the Operation of Onshore Hydrocarbon Pipelines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emil%20Aliyev">Emil Aliyev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main focus of this conference paper is on the aspects of the environmental sustainability of onshore hydrocarbon pipelines. The latter is notorious for being a source of major environmental contamination and a consumer of vast amounts of natural resources such as water, land, steel, etc. Therefore, the environmentally sustainable operation of pipelines is a concern that requires attention and research. The geographical scope of the paper is confined to onshore hydrocarbon pipelines operated in the Middle East region. The research contains elements of originality as it draws on the author’s field experience and practical implementation of environmental and sustainability solutions in a major Middle East-based pipeline organization. The authors describe some of the most common significant environmental aspects of pipeline operations and provide examples of various approaches and technologies that can be successfully utilized to make pipelines more environmentally sustainable. The author concludes that the operation of onshore hydrocarbon pipelines can be made environmentally sustainable. This can be achieved by adopting a systematic framework, focusing limited resources on significant aspects, integrating a circular economy into day-to-day activities, and having strong management support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipelines" title="pipelines">pipelines</a>, <a href="https://publications.waset.org/abstracts/search?q=onshore%20hydrocarbon%20pipelines" title=" onshore hydrocarbon pipelines"> onshore hydrocarbon pipelines</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20sustainability" title=" environmental sustainability"> environmental sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=significant%20environmental%20aspects" title=" significant environmental aspects"> significant environmental aspects</a> </p> <a href="https://publications.waset.org/abstracts/160305/aspects-of-environmental-sustainability-in-the-operation-of-onshore-hydrocarbon-pipelines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">477</span> Studying the Effect of Hydrocarbon Solutions on the Properties of Epoxy Polymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Hasan%20Omar">Mustafa Hasan Omar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The destruction effect of hydrocarbon solutions on concrete besides its high permeability have led researchers to try to improve the performance of concrete exposed to these solutions, hence improving the durability and usability of oil concrete structures. Recently, polymer concrete is considered one of the most important types of concrete, and its behavior after exposure to oil products is still unknown. In the present work, an experimental study has been carried out, in which the prepared epoxy polymer concrete immersed in different types of hydrocarbon exposure solutions (gasoline, kerosene, and gas oil) for 120 days and compared with the reference concrete left in the air. The results for outdoor specimens indicate that the mechanical properties are increased after 120 days, but the specimens that were immersed in gasoline, kerosene, and gas oil for the same period show a reduction in compressive strength by -21%, -27% and -23%, whereas in splitting tensile strength by -19%, -24% and -20%, respectively. The reductions in ultrasonic pulse velocity for cubic specimens are -17%, -22% and -19% and in cylindrical specimens are -20%, -25% and -22%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title="epoxy resin">epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20solutions" title=" hydrocarbon solutions"> hydrocarbon solutions</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20concrete" title=" polymer concrete"> polymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20pulse%20velocity" title=" ultrasonic pulse velocity"> ultrasonic pulse velocity</a> </p> <a href="https://publications.waset.org/abstracts/110602/studying-the-effect-of-hydrocarbon-solutions-on-the-properties-of-epoxy-polymer-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">476</span> Evaluation of Hydrocarbon Prospects of 'ADE' Field, Niger Delta </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluseun%20A.%20Sanuade">Oluseun A.

The field is located in the offshore Niger Delta where water depth ranges from 450 to 800 m. The objectives of this study are to explore deeper prospects and to ascertain the kind of traps that are favorable for the accumulation of hydrocarbon in the field. Six horizons with major and minor faults were identified and mapped in the field. Time structure maps of these horizons were generated and using the available check-shot data the maps were converted to top structure maps which were used to calculate the hydrocarbon volume. The results show that regional structural highs that are trending in northeast-southwest (NE-SW) characterized a large portion of the field. These highs were observed across all horizons revealing a regional post-depositional deformation. Three prospects were identified and evaluated to understand the different opportunities in the field. These include stratigraphic pinch out and bi-directional downlap. The results of this study show that the field has potentials for new opportunities that could be explored for further studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon" title="hydrocarbon">hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=play" title=" play"> play</a>, <a href="https://publications.waset.org/abstracts/search?q=prospect" title=" prospect"> prospect</a>, <a href="https://publications.waset.org/abstracts/search?q=stratigraphy" title=" stratigraphy"> stratigraphy</a> </p> <a href="https://publications.waset.org/abstracts/86819/evaluation-of-hydrocarbon-prospects-of-ade-field-niger-delta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">475</span> Hyperspectral Band Selection for Oil Spill Detection Using Deep Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmau%20Mukhtar%20Ahmed">Asmau Mukhtar Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Duran"> Olga Duran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrocarbon (HC) spills constitute a significant problem that causes great concern to the environment. With the latest technology (hyperspectral images) and state of the earth techniques (image processing tools), hydrocarbon spills can easily be detected at an early stage to mitigate the effects caused by such menace. In this study; a controlled laboratory experiment was used, and clay soil was mixed and homogenized with different hydrocarbon types (diesel, bio-diesel, and petrol). The different mixtures were scanned with HYSPEX hyperspectral camera under constant illumination to generate the hypersectral datasets used for this experiment. So far, the Short Wave Infrared Region (SWIR) has been exploited in detecting HC spills with excellent accuracy. However, the Near-Infrared Region (NIR) is somewhat unexplored with regards to HC contamination and how it affects the spectrum of soils. In this study, Deep Neural Network (DNN) was applied to the controlled datasets to detect and quantify the amount of HC spills in soils in the Near-Infrared Region. The initial results are extremely encouraging because it indicates that the DNN was able to identify features of HC in the Near-Infrared Region with a good level of accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon" title="hydrocarbon">hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=Deep%20Neural%20Network" title=" Deep Neural Network"> Deep Neural Network</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20wave%20infrared%20region" title="short wave infrared region">short wave infrared region</a>, <a href="https://publications.waset.org/abstracts/search?q=near-infrared%20region" title=" near-infrared region"> near-infrared region</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperspectral%20image" title=" hyperspectral image"> hyperspectral image</a> </p> <a href="https://publications.waset.org/abstracts/153072/hyperspectral-band-selection-for-oil-spill-detection-using-deep-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">474</span> Characterization of Petrophysical Properties of Reservoirs in Bima Formation, Northeastern Nigeria: Implication for Hydrocarbon Exploration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Efomeh%20Omolaiye">Gabriel Efomeh Omolaiye</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Ajadi"> Jimoh Ajadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olatunji%20Seminu"> Olatunji Seminu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ayoola%20Jimoh"> Yusuf Ayoola Jimoh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ubulom%20Daniel"> Ubulom Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Identification and characterization of petrophysical properties of reservoirs in the Bima Formation were undertaken to understand their spatial distribution and impacts on hydrocarbon saturation in the highly heterolithic siliciclastic sequence. The study was carried out using nine well logs from Maiduguri and Baga/Lake sub-basins within the Borno Basin. The different log curves were combined to decipher the lithological heterogeneity of the serrated sand facies and to aid the geologic correlation of sand bodies within the sub-basins. Evaluation of the formation reveals largely undifferentiated to highly serrated and lenticular sand bodies from which twelve reservoirs named Bima Sand-1 to Bima Sand-12 were identified. The reservoir sand bodies are bifurcated by shale beds, which reduced their thicknesses variably from 0.61 to 6.1 m. The shale content in the sand bodies ranged from 11.00% (relatively clean) to high shale content of 88.00%. The formation also has variable porosity values, with calculated total porosity ranged as low as 10.00% to as high as 35.00%. Similarly, effective porosity values spanned between 2.00 to 24.00%. The irregular porosity values also accounted for a wide range of field average permeability estimates computed for the formation, which measured between 0.03 to 319.49 mD. Hydrocarbon saturation (Sh) in the thin lenticular sand bodies also varied from 40.00 to 78.00%. Hydrocarbon was encountered in three intervals in Ga-1, four intervals in Da-1, two intervals in Ar-1, and one interval in Ye-1. Ga-1 well encountered 30.78 m thick of hydrocarbon column in 14 thin sand lobes in Bima Sand-1, with thicknesses from 0.60 m to 5.80 m and average saturation of 51.00%, while Bima Sand-2 intercepted 45.11 m thick of hydrocarbon column in 12 thin sand lobes with an average saturation of 61.00% and Bima Sand-9 has 6.30 m column in 4 thin sand lobes. Da-1 has hydrocarbon in Bima Sand-8 (5.30 m, Sh of 58.00% in 5 sand lobes), Bima Sand-10 (13.50 m, Sh of 52.00% in 6 sand lobes), Bima Sand-11 (6.20 m, Sh of 58.00% in 2 sand lobes) and Bima Sand-12 (16.50 m, Sh of 66% in 6 sand lobes). In the Ar-1 well, hydrocarbon occurs in Bima Sand-3 (2.40 m column, Sh of 48% in a sand lobe) and Bima Sand-9 (6.0 m, Sh of 58% in a sand lobe). Ye-1 well only intersected 0.5 m hydrocarbon in Bima Sand-1 with 78% saturation. Although Bima Formation has variable saturation of hydrocarbon, mainly gas in Maiduguri, and Baga/Lake sub-basins of the research area, its highly thin serrated sand beds, coupled with very low effective porosity and permeability in part, would pose a significant exploitation challenge. The sediments were deposited in a fluvio-lacustrine environment, resulting in a very thinly laminated or serrated alternation of sand and shale beds lithofacies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bima" title="Bima">Bima</a>, <a href="https://publications.waset.org/abstracts/search?q=Chad%20Basin" title=" Chad Basin"> Chad Basin</a>, <a href="https://publications.waset.org/abstracts/search?q=fluvio-lacustrine" title=" fluvio-lacustrine"> fluvio-lacustrine</a>, <a href="https://publications.waset.org/abstracts/search?q=lithofacies" title=" lithofacies"> lithofacies</a>, <a href="https://publications.waset.org/abstracts/search?q=serrated%20sand" title=" serrated sand"> serrated sand</a> </p> <a href="https://publications.waset.org/abstracts/135605/characterization-of-petrophysical-properties-of-reservoirs-in-bima-formation-northeastern-nigeria-implication-for-hydrocarbon-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">473</span> Advancements in Hydraulic Fracturing for Unconventional Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salar%20Ahmed%20Ali">Salar Ahmed Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydraulic fracturing has revolutionized the extraction of unconventional oil and gas resources, significantly increasing global energy reserves.
