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.

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?

The U.S. Gulf of Mexico often receives attention for its hydrocarbon potential in the Upper Jurassic and younger rocks in deep and shallow water. Increasingly more people are looking to another potential habitat for hydrocarbons, the syn-rift and associated sections, also known as the Gulf of Mexico pre-salt.

The Tuscaloosa Marine Shale has been a tantalizing target for many years. It's an important source rock, but it has been difficult to successfully complete and produce. Now there is new hope as researchers and their work is receiving support. Welcome to an interview with Mehdi Mokhtari at the University of Louisiana in Lafayette. His Tuscaloosa Marine Shale consortium has recently received support from the United States Department of Energy to explore new technologies for economically drilling and completing the Tuscaloosa Marine Shale.

VG Abstract

In 1991, Gulf Indonesia and its partners discovered South Sumatra Basin’s first major gas field at Dayung in the Corridor PSC. A key feature of this field is that most of the reserves are held within fractured basement rocks of pre-Tertiary age.
