The AAPG Women’s Network is excited to kick off the new AAPG fiscal year with a new leadership team and some new initiatives. The AAPGWN is currently working hard to roll out new initiatives, events, and partnerships. The goal of these programs is to expand our community of geoscientists, provide career development resources to women and increase knowledge sharing among our global members.

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.

Explorer Historical Highlights

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?

In the wake of a long hiatus from discoveries that nearly made Oman obsolete in the industry, potential is brewing again. This time, it is offshore where Eni recently began drilling the country’s first deepwater well. Eni CEO Claudio Descalzi announced, “The first drilling that we are doing in the region will be in Oman in February. It will be the first (deepwater) offshore drilling in Block 52 in Oman, so it’s quite important.” Block 52 is a vast area of approximately 90,000 square kilometers off the southern and southeastern seaboard of Oman, with water depths up to 3,000 meters. The exploration well was planned just seven months after the completion of seismic data acquisition and is likely to show gas-condensate.

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?”

Traveling to the Middle East is something that I get a lot of questions about, particularly from colleagues and friends in the United States and Europe who have never done so. Based on the headlines they read, they’re surprised to hear me say that it is one of my favorite places to travel. The people of the Kingdom of Saudi Arabia warmly welcomed IPTC attendees, and a spirit of hospitality pervades cultures in the Middle East. You need to experience it. And next month we, AAPG, together with EAGE and SEG, will enable you to do just that as we launch GEO 2020, the 14th Middle East Geosciences Conference and Exhibition in Bahrain, with the theme “Geosciences in the Digital World: 2020 and Beyond.”

Join us in Salzburg, the “castle of salt” and cradle of Mozart and Doppler, for a meeting aimed at bringing together different perspectives in the science of evaporite basins: from their formation to their deformation, from description and characterization to modelling. Exploratory success in evaporite-rich basins worldwide has depended on the role of evaporites as a deformable substrate, as a seal, or even as a good thermal conductor. The aim of this workshop is to improve our understanding and predictive ability by addressing evaporite systems in an integrated manner, all the way from precipitation to structuration, and exploring the multiple properties of evaporite sequences. The pre- and post-meeting field trips will also explore the salt mining heritage of the region, first exploited by the Celts 3500 years ago, and the salt-related structures of the Northern Calcareous Alps.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.
