Explorer Historical Highlights

During the 1980s, early prospecting in deepwater margins was the simple extension of prolific updip producing basins that were charged. However, the migration of petroleum exploration and development into deepwater was fraught with challenges. For engineers and geologists, one of our biggest challenges was to overcome our collective lack of understanding about the geology of deepwater. We had to revisit everything we thought we knew, one paradigm shift after another.

Welcome to a new series in the AAPG Learn! Blog entitled “My Favorite Outcrop.” In this series, we chat with geoscientists who tell us about their favorite outcrops encountered during their work in the field. Today we meet with Clara Abu, who is one of the founding members of the Salt Basins Technical Interest Group. One of her favorite outcrops was in Tusher Canyon, Utah, featured in the photo.

Understanding the role and influence of salt in the subsurface has been the key to many hydrocarbon discoveries and appraisals and more recently carbon & hydrogen capture and storage, and geothermal interests. Now, AAPG has a new Technical Interest Group, co-founded and co-chaired by Clara Abu (Ph.D Candidate Imperial College), Rachelle Kernen Ph.D., Leonardo Muniz Pichel Ph.D., Clara Rodriguez Ph.D., and Tim Shin, MSc. Welcome to an interview with one of the co-founders, Clara Abu.

Emma Giddens was a California girl who fell in love with carbonate rocks, excelled in nearly everything she tried, led her IBA team to a Selley Cup victory and even as a graduate student was known internationally for her “pioneering” research. In fact, professors at three schools marveled at her passion for geology, her intelligence, her kindness and mentorship of fellow students. Tragically, Giddens died shortly after receiving word that her research was being honored with an AAPG Foundation Grant-in-Aid.

Explorer Article

On July 30, NASA’s Jet Propulsion Laboratory launched the Mars 2020 Perseverance rover. Perseverance is destined to land at Jezero crater on Feb. 18, 2021, with the most sophisticated kit of geology tools ever assembled for an astrogeology mission. AAPG, as an institution dedicated to exploring for resource commodities, looks to our future in space through the Astrogeology Committee and the Energy Minerals Division. We emphasize the use of geosciences in the development of off-world exploration energy and other natural resources for development in the foreseeable future. Water resources in space, on the moon and on Mars, will become the energy commodity analog of oil on Earth.

“Wait! There is a short cut. Turn right from here”. That’s probably the sound of an electric current bypassing the resistive hydrocarbons, in a maze or network of porous media, when traveling from transmitter to receiver. This workshop will serve the participants need with the up to date advancements in describing and characterizing low resistivity and low contrast pay, and eventually, maximize resources.

Instructors: Ricardo Pereira, PARTEX Oil and Gas & Instituto Dom Luiz Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: To be determined Limit: 20 Participants Includes: Hotel Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am SANA Metropolitan Hotel 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.

The “Great Crew Change” has become the “Competence Train Wreck” due to the repeated personal mis-management practices of our industry and again not anticipating the known volatility of commodity prices. Despite this, hydrocarbon based energy will continue to comprise over 60% of the world’s energy mix for at least the next half century and of that energy need over half of it has yet to be found! Personal experience in working for National Oil Companies, Parastatals, large independent oil companies, small independents, as an independent and as a consultant have given me the perspective of some of the best and some of the worst of the exploration practices the industry has to offer.

DL Abstract

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

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.
