At times, the scientific back-and-forth argument has resembled a slow-motion tennis match, with a new volley coming every few years. Now, Daniel Xia thinks he has helped deliver a winning smash across the net. His findings were most clearly laid out in a recent article “Validity of geochemical signatures of abiotic hydrocarbon gases on Earth,” by Xia and coauthor Yongli Gao, published in the Journal of the Geological Society. </p></div></div><a class='show-more'>Show more</a> </div> <meta itemprop="inLanguage" content="English"> <span style="display: none;" itemprop="publisher" itemscope="" itemtype="https://schema.org/Organization"> <span itemprop="name">American Association of Petroleum Geologists (AAPG)</span> <meta itemprop="logo" content="https://img.aapg.org/Portals/0/images/_site/AAPG-logo-footer.png"> </span> <div class="morelink">Added on <span itemprop="datePublished" class="schema">01 October, 2022</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Article">  <div class="litImage Learn!

Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America. </p></div></div><a class='show-more'>Show more</a> <p style="/*float: right; height: auto; margin: 0 0 15px; width: 81%;*/"><a class="dnnPrimaryAction" href='//www.aapg.org/career/training/in-person/distinguished-lecturers/arrange-for-a-lecturer'>Request a visit from Kurt W.

These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.</p></div></div><a class='show-more'>Show more</a> <p style="/*float: right; height: auto; margin: 0 0 15px; width: 81%;*/"><a class="dnnPrimaryAction" href='//www.aapg.org/career/training/in-person/visiting-geoscientists/request-form'>Request a visit from Ameed Ghori!</a></p> </div> <meta itemprop="inLanguage" content="English"> <span style="display: none;" itemprop="publisher" itemscope="" itemtype="https://schema.org/Organization"> <span itemprop="name">American Association of Petroleum Geologists (AAPG)</span> <meta itemprop="logo" content="https://img.aapg.org/Portals/0/images/_site/AAPG-logo-footer.png"> </span> <div class="morelink">Added on <span itemprop="datePublished" class="schema">14 April, 2016</span></div> </div>     </div> <script type="text/javascript"> /*var moreText = "Show details", lessText = "Hide details", moreButton = $("a.readmorebtn"); moreButton.click(function () { var $this = $(this); $this.text($this.text() == moreText ? lessText : moreText).nextAll(".more").slideToggle("fast"); }); */ $('.show-more').each(function() { var parent_id = "#" + $(this).parent("div").attr("id"); $(this).click(function() { var minimum_height = (parseInt($(parent_id + ' .show-more-snippet .summary').css('line-height'), 10) * 5) + 'px'; console.log(minimum_height); //if($(parent_id + ' .show-more-snippet').css('height') != '35px'){ if($(parent_id + ' .show-more-snippet').css('height') != minimum_height){ //$(parent_id + ' .show-more-snippet').stop().animate({height: '35px'}, 200); $(parent_id + ' .show-more-snippet').stop().animate({height: minimum_height}, 200).addClass("fade"); $(this).text('Show more'); }else{ $(parent_id + ' .show-more-snippet').css({height:'100%'}).removeClass("fade"); var xx = $(parent_id + ' .show-more-snippet').height(); //$(parent_id + ' .show-more-snippet').css({height:'35px'}); $(parent_id + ' .show-more-snippet').css({height: minimum_height}); $(parent_id + ' .show-more-snippet').stop().animate({height: xx}, 400); // ^^ The above is beacuse you can't animate css to 100% (or any percentage).
