The Paleogene (Wilcox) Deepwater Play

Joshua Rosenfeld’s article in the April EXPLORER issue’s Historical Highlights provides an interesting compilation of observations selected to support an unproven hypothesis: that the large influx of Paleogene Wilcox sandstones in the Gulf of Mexico can be linked to a major evaporative drawdown of the basin, loosely aligned with and possibly triggering the Paleocene-Eocene thermal event. We offer our observations based on decades of oil industry experience working the Wilcox play, more than 55 peer- reviewed academic papers and one book on Gulf of Mexico sedimentary basin.

Paleogene Drawdown of the Gulf of Mexico?

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?

Can Big River Theory Explain the Permian’s Prolific Production?

The history of the Permian Basin reads like a detective novel in reverse. Geoscientists know how the story turns out. They’re trying to determine exactly how it started. Robert Stern, a professor of geosciences at the University of Texas at Dallas, thinks he and a group of fellow scientists have solved one important part of the mystery. Stern. “We know oil is limited by the nutrients. Oil just doesn’t suddenly appear,” he said. That raises the question, “How did all those nutrients get there?”

Underexplored Rub' al Khali Basin Could Hold Major Unconventional Potential

It is one of the most remote places on the planet and home to the largest sand desert in the world. Virtually uninhabited and underexplored, the Rub’ al Khali basin, known as “the Empty Quarter” in Arabic, covers more than a fourth of the southeastern part of the Saudi Arabian peninsula. While the area has been explored in the past, perhaps most notably by Max Steineke, the American geologist known for making the first oil discovery in Saudi Arabia in 1938, and then publicly again in the early 2000s by international oil companies, the basin appears to be of increasing interest once more.

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.

Leadership and Strategic Thinking For a Pandemic and Post-Pandemic World

In the span of a mere few months, the much of the world went from a state of exuberant self-actualization to the most primal level of survival (health, food, shelter) insecurity. Consequently, the world has changed. Shock change due to pandemic-triggered chain reactions, supply / demand and price instability, rapid technological innovation, new plays and changing markets, distributed teams and workforces, the powerful force of social media, shortages of technical expertise, and supply chain issues have come together to create new challenges and opportunities for leadership. We will analyze how the issues relate to the oil and gas business (exploration, development, oilfield services, support services, financial sector) and we will propose solutions for immediate real-world emergencies, together with longer term challenges. In addition, we will evaluate what prominent thinkers and academics have written about leadership and strategic planning.

Yet-to-Find Oil Potential of the Brazilian Presalt - Portuguese Talk

Em 2011 e 2015, apresentei uma avaliação do potencial de petróleo ainda por descobrir (YTF – Yet to Find) na região brasileira do pré-sal, utilizando uma ferramenta de modelagem de exploração e um método de simulação estocástica (Monte Carlo) para estimar as acumulações potenciais já descobertas e as restantes para ser descobertas. Embora da metodologia robusta usada, é compreensível que, à luz dos novos preços do petróleo, muito mais baixos, a avaliação do óleo YTF possa ser questionada sobre o quão realista poderia ser, num cenário prolongado de preço baixo do petróleo. Em 2016, apresentei essa avaliação, para preços do petróleo abaixo de US$ 50/bbl. Agora, com os preços do petróleo ainda mais baixos que podem representar um novo cenário de redução por mais tempo, volto a revisar as avaliações anteriores. Os resultados são apresentados no contexto de importantes implicações geopolíticas para em regiões do mundo onde os recursos de petróleo e gás provavelmente continuarão viáveis, apesar dos preços baixos do petróleo, e os rearranjos geopolíticos que isso implica.

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.
