Introducing the Distinguished Lecture Program’s Magnificent Seven

Sometimes, challenging times call for dramatic objectives – and for a geoscience world still being redefined after years of upheaval, that’s exactly what the doctor ordered. This year’s new slate of AAPG Distinguished Lecturers has been determined, and in doing so, AAPG announces its own version of the Magnificent Seven: a diverse group of experts with international experience, specific knowledge and a hint of geoscience star power who have been selected to inform, improve and inspire geoscientists around the world.

Explorer President’s Column By Steven Goolsby

Embrace the Controversy

Controversy can be a good thing, and sometimes, the more contentious things are, the better. Many great examples of this were discussed in my first geologic graduate course, the subject of which was “The History of the Science of Geology.” It was the controversy and debate itself that provided the greatest contribution to the science of geology – not the theories. Why is it important to recognize that controversy can be a good thing – important for AAPG and a good subject for my column in the EXPLORER? The answer is that controversy can also lead to the growth and improvement of a scientific society.

Book Review: ‘How the Mountains Grew’

What makes John Dvorak’s “How the Mountains Grew: A New Geological History of North America” so special? Dvorak “connects the dots,” so to speak, between places of geologic wonder many geoscientists already know. The book provides context to well-known outcrops and fundamental geologic processes. There is still a lot to learn for those who have studied geology for many years.

The Petroleum Industry is the Backbone of Energy

After the past year as president of the Division of Environmental Geosciences, my three big takeaways are that the world needs energy, all forms of energy are in transition, and geoscientists are needed to explore for and develop energy – now and in the future. In every future energy scenario, oil and gas will be needed for decades at various levels to contribute to the global energy mix.

Instructors: Ricardo Pereira, GeoBioTec - Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa. Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: €190 - Local VAT applicable Limit: 20 Participants Includes: Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am Hotel Dom Pedro Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

A Simplified Guide to Sequence Stratigraphy

In the past 3 decades the sequence stratigraphy jargon has proliferated, resulting in multiple definitions of the same 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.

DL Abstract By Tao Sun

Integrated Reservoir Characterization and Modeling with Computational Stratigraphy

As oil and gas exploration and production occur in deeper basins and more complex geologic settings, accurate characterization and modeling of reservoirs to improve estimated ultimate recovery (EUR) prediction, optimize well placement and maximize recovery become paramount. 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.

VG Abstract By Keith Gerdes

Tethyan Carbonates - Linking Tropical Seas and Crashing Plates to Some of the Largest Oil and Gas Fields in the World

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.
