Existing technologies for reservoir characterization and modeling have proven inadequate for delivering detailed 3D predictions of reservoir architecture, connectivity and rock quality at scales that impact subsurface flow patterns and reservoir performance. Because of the gap between the geophysical and geologic data available (seismic, well logs, cores) and the data needed to model rock heterogeneities at the reservoir scale, constraints from external analog systems are needed. Existing stratigraphic concepts and deposition models are mostly empirical and seldom provide quantitative constraints on fine-scale reservoir heterogeneity. Current reservoir modeling tools are challenged to accurately replicate complex, nonstationary, rock heterogeneity patterns that control connectivity, such as shale layers that serve as flow baffles and barriers. </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 Tao Sun!</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">20 July, 2022</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="https://schema.org/Article"> <div class="litImage VG Abstract 1plus4 Rotation Carbonates Sedimentology and Stratigraphy " style="position: relative;"> <a href='https://www.aapg.org/career/training/in-person/visiting-geoscientist/abstract/Articleid/22390/tethyan-carbonates-linking-tropical-seas-and-crashing-plates-to-some-of-the-largest-oil-and-gas-fields-in-the-world'> <div class="image-overlay "></div> <noscript data-slimmage>  <img itemprop="image" class="lazy-sidebar" data-original="/Portals/0/PackFlashItemImages/WebReady/vg-abstract-Tethyan-Carbonates-Linking-Tropical-Seas-Crashing-Plates-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" src="/portals/0/PackFlashItemImages/WebReady/vg-abstract-Tethyan-Carbonates-Linking-Tropical-Seas-Crashing-Plates-hero.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" alt="AAPG"> </noscript> </a> </div> <div class="text VG Abstract 1plus4 Rotation Carbonates Sedimentology and Stratigraphy " id="pfid_22390"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">VG Abstract</span> <span class="author" itemprop="author">By Keith Gerdes</span> </div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/career/training/in-person/visiting-geoscientist/abstract/Articleid/22390/tethyan-carbonates-linking-tropical-seas-and-crashing-plates-to-some-of-the-largest-oil-and-gas-fields-in-the-world'>Tethyan Carbonates - Linking Tropical Seas and Crashing Plates to Some of the Largest Oil and Gas Fields in the World</a> </div>  <div class="show-more-snippet fade"><div class="summary" itemprop="description"><p>The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.</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 Keith Gerdes!</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">24 August, 2015</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="https://schema.org/Article"> <div class="litImage DL Abstract 1plus4 Rotation DL Abstracts Current (Carbonate) Shelf Sand Deposits Carbonates Sedimentology and Stratigraphy " style="position: relative;"> <a href='https://www.aapg.org/career/training/in-person/distinguished-lecturer/abstract/articleid/67628'> <div class="image-overlay "></div> <noscript data-slimmage>  <img itemprop="image" class="lazy-sidebar" data-original="/Portals/0/PackFlashItemImages/WebReady/AAPG DL 24-25-Lesli Wood The Shelf is a Dangerous Place-Hero Image.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" src="/portals/0/PackFlashItemImages/WebReady/AAPG DL 24-25-Lesli Wood The Shelf is a Dangerous Place-Hero Image.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" alt="AAPG"> </noscript> </a> </div> <div class="text DL Abstract 1plus4 Rotation DL Abstracts Current (Carbonate) Shelf Sand Deposits Carbonates Sedimentology and Stratigraphy " id="pfid_67628"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">DL Abstract</span> <span class="author" itemprop="author">By Lesli Wood</span> </div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/career/training/in-person/distinguished-lecturer/abstract/articleid/67628'>The Shelf is a Dangerous Place: Surfing the Cretaceous Seaways</a> </div>  <div class="summary" itemprop="description"><p>Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments. </p></div> <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 Lesli Wood!</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">19 August, 2024</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 ?
