Field examinations revealed abnormal clinical signs with sometimes a quick death of affected trees. Entomologic investigations have confirmed the absence of phytophagous insects on dead trees. Further investigations by questioning farmers on the global management of palm groves visited (Irrigation, water quality used, soil type, etc.) did not establish any relationship between these aspects and the death of palm trees, which naturally pushed us to focus our investigations for research on fungal pathogens. Thus, laboratory studies were conducted to know the real causes of this phenomenon, 13 fungi were found on different parts of the dead palm trees. The flowing fungal types were identified: 1-Diplodia phoenicum, 2-Theilaviopsis paradoxa, 3-Phytophthora sp, 4-Helminthosporium sp, 5-Stemphylium botryosum, 6-Alternaria sp, 7-Aspergillus niger, 8-Aspergillus sp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20tree" title="palm tree">palm tree</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20pathogens" title=" fungal pathogens"> fungal pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=Oued%20Righ" title=" Oued Righ "> Oued Righ </a> </p> <a href="https://publications.waset.org/abstracts/14128/isolation-and-identification-of-fungal-pathogens-in-palm-groves-of-oued-righ" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14128.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">411</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">4</span> Experimental Study on Improving the Engineering Properties of Sand Dunes Using Random Fibers-Geogrid Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adel%20M.%20Belal">Adel M.

However, this development is facing challenges preventing land development and agriculture development. Desertification and moving sand dunes in the west sector of Egypt are considered the major obstacle that is blocking the ideal land use and development. In the proposed research, the sandy soil is treated biologically using <em>Bacillus pasteurii</em> bacteria as these bacteria have the ability to bond the sand partials to change its state of loose sand to cemented sand, which reduces the moving ability of the sand dunes. The procedure of implementing the Microbial Induced Carbonate Precipitation Technique (MICP) technique is examined, and the different factors affecting on this process such as the medium of bacteria sample preparation, the optical density (OD600), the reactant concentration, injection rates and intervals are highlighted. Based on the findings of the MICP treatment for sandy soil, conclusions and future recommendations are reached. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20stabilization" title="soil stabilization">soil stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20treatment" title=" biological treatment"> biological treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20induced%20carbonate%20precipitation%20%28MICP%29" title=" microbial induced carbonate precipitation (MICP)"> microbial induced carbonate precipitation (MICP)</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20cementation" title=" sand cementation"> sand cementation</a> </p> <a href="https://publications.waset.org/abstracts/71459/characterization-of-the-microbial-induced-carbonate-precipitation-technique-as-a-biological-cementing-agent-for-sand-deposits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71459.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">243</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">2</span> Uniqueness and Repeatability Analysis for Slim Tube Determined Minimum Miscibility Pressure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waqar%20Ahmad%20Butt">Waqar Ahmad Butt</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Vakili%20Nezhaad"> Gholamreza Vakili Nezhaad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Soud%20Al%20Bemani"> Ali Soud Al Bemani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Al%20Wahaibi"> Yahya Al Wahaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Miscible gas injection processes as secondary recovery methods can be applied to a huge number of mature reservoirs to improve the trapped oil displacement. Successful miscible gas injection processes require an accurate estimation of the minimum miscibility pressure (MMP) to make injection process feasible, economical, and effective. There are several methods of MMP determination like slim tube approach, vanishing interfacial tension and rising bubble apparatus but slim tube is the deployed experimental technique in this study. Slim tube method is assumed to be non-standardized for MMP determination with respect to both operating procedure and design. Therefore, 25 slim tube runs were being conducted with three different coil lengths (12, 18 and 24 m) of constant diameter using three different injection rates (0.08, 0.1 and 0.15 cc/min) to evaluate uniqueness and repeatability of determined MMP. A trend of decrease in MMP with increase in coil length was found. No unique trend was found between MMP and injection rate. Lowest MMP and highest recovery were observed with highest coil length and lowest injection rate. It shows that slim tube measured MMP does not depend solely on interacting fluids characteristics but also affected by used coil selection and injection rate choice. Therefore, both slim tube design and procedure need to be standardized. It is recommended to use lowest possible injection rate and estimated coil length depending upon the distance between injections and producing wells for accurate and reliable MMP determination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coil%20length" title="coil length">coil length</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20rate" title=" injection rate"> injection rate</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20miscibility%20pressure" title=" minimum miscibility pressure"> minimum miscibility pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20contacts%20miscibility" title=" multiple contacts miscibility"> multiple contacts miscibility</a> </p> <a href="https://publications.waset.org/abstracts/50436/uniqueness-and-repeatability-analysis-for-slim-tube-determined-minimum-miscibility-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50436.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">253</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">1</span> Comparative Evaluation of Vanishing Interfacial Tension Approach for Minimum Miscibility Pressure Determination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waqar%20Ahmad%20Butt">Waqar Ahmad Butt</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Vakili%20Nezhaad"> Gholamreza Vakili Nezhaad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Soud%20Al%20Bemani"> Ali Soud Al Bemani</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Al%20Wahaibi"> Yahya Al Wahaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Minimum miscibility pressure (MMP) plays a great role in determining the displacement efficiency of different gas injection processes. Experimental techniques for MMP determination include industrially recommended slim tube, vanishing interfacial tension (VIT) and rising bubble apparatus (RBA). In this paper, MMP measurement study using slim tube and VIT experimental techniques for two different crude oil samples (M and N) both in live and stock tank oil forms is being presented. VIT measured MMP values for both 'M' and 'N' live crude oils were close to slim tube determined MMP values with 6.4 and 5 % deviation respectively. Whereas for both oil samples in stock tank oil form, VIT measured MMP showed a higher unacceptable deviation from slim tube determined MMP. This higher difference appears to be related to high stabilized crude oil heavier fraction and lack of multiple contacts miscibility. None of the different nine deployed crude oil and CO2 MMP computing correlations could result in reliable MMP, close to slim tube determined MMP. Since VIT determined MMP values for both considered live crude oils are in close match with slim tube determined MMP values, it confirms reliable, reproducible, rapid and cheap alternative for live crude oil MMP determination. Whereas VIT MMP determination for stock tank oil case needed further investigation about stabilization / destabilization mechanism of oil heavier ends and multiple contacts miscibility development issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimum%20miscibility%20pressure" title="minimum miscibility pressure">minimum
