We met thousands of fellow geoscientists by attending, and organizing, hundreds of technical talks for 39 years. We learned about exciting discoveries, plays and technology from those who made them happen. Along the way, we became friends with a few legends. We are grateful for the deep friendships that arose while serving as HGS volunteers. With a grateful heart, we are happy to share our committee’s plans to celebrate the centennial year. </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 April, 2023</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Article">  <div class="litImage Explorer Foundation Update 1plus4 Rotation 3D Seismic CCUS Clastics Climate Change Deep Sea / Deepwater Environmental Geophysics Member Sedimentology and Stratigraphy Seismic Seismic Attributes SEPM Sequence Stratigraphy Student " style="position: relative;"> <a href='https://www.aapg.org/publications/news/explorer/column/articleid/64797' > <div class="image-overlay "></div> <noscript data-slimmage>  <img itemprop="image" class=" lazy " data-original="/Portals/0/PackFlashItemImages/WebReady/the-trials-and-triumphs-of-AAPG-distinguished-lecture-program-hero2.jpg?width=200&height=200&mode=crop&anchor=middlecenter&encoder=freeimage&progressive=true&quality=90&scale=both&bgcolor=ffffff" src="/portals/0/PackFlashItemImages/WebReady/the-trials-and-triumphs-of-AAPG-distinguished-lecture-program-hero2.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 Explorer Foundation Update 1plus4 Rotation 3D Seismic CCUS Clastics Climate Change Deep Sea / Deepwater Environmental Geophysics Member Sedimentology and Stratigraphy Seismic Seismic Attributes SEPM Sequence Stratigraphy Student " id="pfid_64797"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">Explorer Foundation Update</span> <span itemprop="author">By Vern Stefanic</span> </div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/publications/news/explorer/column/articleid/64797' >The Trials and Triumphs of AAPG’s Distinguished Lecture Program</a> </div>  <div class="summary" itemprop="description"><p>Being an AAPG Distinguished Lecturer, from the very first speaking tour in 1941, was always a prestigious achievement and a source of honor and pride for those selected as speakers.

In addition to expanding our knowledge on sedimentary systems that cover 70 percent of our planet, deepwater systems host promising resources and energy potential for the future. Their characteristic high-rate productivity also means fewer wells, which is good news for lower carbon emissions. Deepwater systems also benefit from the highest quality offshore 3-D and 4-D seismic. Thus, we see more clearly with ever-improving technology. Deepwater concepts and paradigms are rapidly evolving.

The sheer eastern escarpment exposes rocks dating from the Pennsylvanian down to 1.25-billion-year-old basement granite.

and colleagues in the mid 70’s, which explains the complex geometries that sediments create as they fill accommodation in response to changes in rates of sedimentation, subsidence, uplift and eustasy. This method was developed based on observations and concepts developed as early as in the 1800’s. Based on this strong scientific foundation, pioneer work from Caster, Sloss, Wheeler, Campbell, and Asquith established the basis for the methodology. These researchers established a new way to correlate stratigraphic units, demonstrating the time-transgressive nature of lithostratigraphic formations.</p></div></div><a class='show-more'>Show

surface or new surfaces and units based on drawings of deposition in response to relative changes in sea level. The close association between base-level changes, the formation of surfaces, and specific stratal stacking that define systems tracts are at the heart of the confusion. This webinar is proposed a back-to-basics approach, emphasizing key observations that can be made from any geologic data: lithofacies, lithofacies association, vertical stacking, stratal geometries, and stratal terminations.</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">06 August, 2020</span></div> </div>  <div class="list-with-images explorer-articles dnnClear" itemscope="" itemtype="http://schema.org/Event">  <div class="litImage Webinar 1plus4 Rotation Sedimentology and Stratigraphy Sequence Stratigraphy Virtual " style="position: relative;"> <a href='https://www.aapg.org/virtual-event/details/articleid/66071' > <div class="image-overlay Virtual "></div> <noscript data-slimmage>  <img itemprop="image" class=" lazy " data-original="/Portals/0/PackFlashItemImages/WebReady/hq-2023-webinar-float-trip-geology-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/hq-2023-webinar-float-trip-geology-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 Webinar 1plus4 Rotation Sedimentology and Stratigraphy Sequence Stratigraphy Virtual " id="pfid_66071"> <div class="author content-type" style="margin-bottom: 0px;"> <span class="content-type">Webinar</span> </div> <div class="city-state-country">Virtual Webinar</div> <div class="dates"><span class="weekday schema">Tuesday, </span>31 October 2023<span class="time schema">, 12:00 p.m.–1:00 p.m.</span></div> <div class="h5" itemprop="headline"> <a itemprop="url" href='https://www.aapg.org/virtual-event/details/articleid/66071' >Cory Godwin - Float Trip Geology - Upper Mississippi - Stratigraphy along the Spring River</a> </div>  <div class="show-more-snippet fade"><div class="summary" itemprop="description"><p>Mississippian strata in the Ottawa County, Oklahoma, within the Tri-State Mining District, are a well-known hosts to MVT lead and zinc ore deposits.

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 ?
