Explorer Historical Highlights

The relatively recent, very large discoveries offshore Brazil have put pre-salt exploration in the South Atlantic back in the foreground. Pre-salt exploration history, however, is far more ancient and marked with some major successes – but also many failures. Here’s a brief overview of this exploration in West Africa until the M’Boundi discovery, which will be described in detail as it brings some lessons that readers can discover for themselves.

In the age of 3-D seismic and digitized well logs, the value of cores and other rock samples may not be obvious. But benefits like those noted by the AAPG in 1948 and described in a 2002 National Research Council report and a recent congressional hearing continue to demonstrate the value of properly archived subsurface samples and data.

At first glance it seems there’s not much overtly new about drilling in the Mississippi Lime – or overtly new about the Mississippi Lime play, either, for that matter – a play that oozes from northern Oklahoma through southern Kansas (and some say, perhaps, to Nebraska).

AAPG is committed to connecting promising original research with much-needed funding and is continually seeking – and finding – new ways to make that potential a reality.

Unconventional plays are producing hundreds of wells within relatively small spaces, and all are cranking out more data than any human could possibly track. It’s a fact that has driven the oil and gas industry to search for technology that can intelligently quantify such data and increase the odds of a discovery.

They were known as the “Flying Florences” in the geological world of Alaska – a nickname so fitting it smacked of the obvious, yet still piqued all kinds of curiosity on the North Slope. In the 1950s, as crews of men braved the hostile climate of the Brooks Range exploring for oil and gas, Florence Weber (nee Robinson) and Florence Collins (nee Rucker) appeared out of nowhere from the sky – steering a Super Cub floatplane over the mountains and landing on the interior lakes of Alaska.

Discover the basic fundamentals of structural geology, the response of natural materials to deformation, and what changes occur due to the application of stress and or strain energy. Practical Geomechanics will be covering the many aspects of exploration, assessment and production phases of petroleum reservoir development.

Looking at a formation as a source rock, then turning around and considering it a viable reservoir requires you to be able to shift your thinking and to analyze a great deal of data in a new way. If you don’t, you risk not understanding the nature of “sweet spots” and how to accurately complete or use reservoir characterization studies.

“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.

Field Seminar
Lisbon, Portugal
Tuesday, 20 June 2023, 8:00 a.m.–5:00 p.m.

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.

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.
