Explorer Historical Highlights

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

Phase decomposition is an interesting technique that can decompose a composite seismic signal into different phase components, and which in turn can help with the characterization of thin target sandstone or carbonate reservoirs. Here we discuss the application of phase decomposition as a reservoir management tool, with the odd phase component (sum of plus 90 degrees and minus 90 degrees phase components) showing better correlation with the wells that control the injection and withdrawal of a natural gas storage reservoir in Denmark.

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.

Explorer Article

Josh Rosenfeld highlighted some perspectives on the Paleogene drawdown hypothesis in the Gulf of Mexico in the April 2020 issue of the EXPLORER, a result of suspected isolation from the world ocean during the Cuban arc-Bahamas collision with implications for Wilcox reservoir deposition. In contrast, John Snedden and authors’ portrayed the Wilcox as a period of normal marine deposition, requiring no such drawdown, in the May 2020 issue. Still another concept was presented by Roger Higgs at the South African 2009 AAPG International Conference and Exhibition, that marine isolation occurred but that fluvial input exceeded evaporation such that the Gulf became brackish, hence the poor development of Wilcox fauna.

It all started in 2002, when Unocal revealed that its Trident-1 well had found 400 meters of 70-percent net Lower Wilcox Formation sand in the deepwater Gulf of Mexico, about 400 kilometers beyond the contemporaneous shelf break offshore south Texas. Art Berman and I gazed at a GOM activity map and pondered how that amount of sand could have been deposited so far out into the basin. Our working hypothesis was that this sand deposit was due to a drop in base level, but we also knew that the worldwide sea level was not in decline at that time. A log of the nearby Shell Great White well shows that this sand deposition began suddenly and ended suddenly. This was also puzzling, since we were trained to expect gradational coarsening-upward bedding during regression and fining-upward during transgression, rather than the sharp contacts we were seeing. Sudden avulsion of a major river in a deltaic environment could produce something like this, but how could it happen far beyond the shelf edge?

“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.

Come along on this 1-day field seminar and tour outcrops in the Serra de Montejunto, just north of Lisbon and on the coast from Porto Novo to Paimogo. 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.

Salt welds form due to salt thinning by mechanical (e.g., salt-flow) and/or chemical (e.g., salt-dissolution) processes. This webinar explores how we use 3-D seismic reflection, borehole, and biostratigraphic data to constrain the thickness and composition of salt welds, and to test the predictions of analytical models for salt welding.

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.
