Last summer, nearly 30 geoscientists and engineers from the Canadian Society for Unconventional Resources trekked through an array of outcrops in the Sulphur Mountain Formation to piece together how the Montney Formation – Western Canada’s most prolific resource play – was formed. Rock by rock, they saw how the outcrops revealed a history of sedimental deposition, sedimentary structures, trace and body fossils, and even a bone bed. And, rather than getting there by airplane or car and hiking over tumultuous terrain, they navigated each nook and cranny from the comfort of their homes. For most CSUR members, it was their first virtual fieldtrip and will likely not be their last.

University geoscience programs face a challenging future as the world emerges from the coronavirus pandemic – one that could have significant and even dire implications for oil and gas. Educators, mostly outside the United States, are already sounding an alarm.

This study is primarily based on a 3-D seismic dataset that covers 1,107 square kilometers of the deepwater Ceará Basin. For this demonstration, the seismic cube was cropped and extends over an area of 765 square kilometers. It covers part of Premier Oil, Cepsa, Chevron and Ecopetrol exploration blocks, as well as ANP’s blocks of permanent offer. Here we present a broad overview of the seismic geomorphology of the study area aiming at delineating the turbidite channels, as the sands are deposited in the channels and can accumulate the hydrocarbons, which can be exploited for the benefits of the petroleum industry, as well as discuss a pitfall associated with the cropping of seismic data.

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.

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.

There is something about colored pencils that we, as geologists, find impossible to resist. From geological maps to field sketches to interpreting seismic on those never-ending rolls of paper taped to the longest corridor wall we can find – what more could any geologist want? Our need for powerful software, paper and colored pencils reflects a fundamental problem in geology and especially exploration: how to manage, analyze and visualize the diversity and wealth of information required to solve exploration problems? Early geologists were faced with the same challenge 200 years ago. It was one of the first petroleum geologists, Thomas Sterry Hunt, who saw the value of paleogeography in exploration, and who, in 1873, first coined the term “paleogeography.”

Touchstone Exploration is the operator of the 184-square kilometer Ortoire Block onshore south eastern Trinidad. The block spans from the villages of Tableland in the west to Pierreville Mayaro in the east and to the very remote areas within the Guayaguayare forest to the south. Structurally, the block covers the greater part of the open east facing Ortoire Syncline which entails Late Miocene Lower Cruse to Pleistocene Mayaro Formation deltaic fill. These passive fordeep infill deposits sit conformably onto a southeastern-verging Early to Middle Miocene fold belt. As such throughout the breadth of the Ortoire Block there are numerous tear fault dissected west-southwest to east-northeast trending anticlines.

Exploration of the Brookian-age Nanushuk and Torok formations on the North Slope of Alaska is a hot topic these days. The Nanushuk and Torok formations are Cretaceous progradational clastic deposits in the Colville basin of Alaska. These formations offer new opportunities to the oil and gas community because of their shallow depth, vast spatial extent, publicly available data, scope of development and other appealing features.

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.

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.

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.

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.
