The project also conducts assessments of undiscovered, technically recoverable hydrocarbon resources. The Gulf Coast Petroleum Systems Project focuses on the onshore and State waters portion of the Gulf Coast basin,...
Controls on Unconventional Oil and Gas Production
This scoping task incorporates insights from new approaches to production of unconventional resources and currently focuses on conducting a pilot assessment of biogenic natural gas resources in the Permian Basin. For the pilot assessment to occur, we are developing a database that will host geochemical parameters known to be suggestive of microbial methanogenesis mined to the reservoir level...

Energy and minerals division tight oil and gas committee: Activities and commodity report for 2019-2020
In 2019, total daily tight oil and gas production increased in the United States month over month, with annualized growth of 14% for oil and 12% for gas. Those gains leveled off in the first quarter of 2020 due to aggressive price competition and increases in international production. Then came the pandemic with a substantially larger dose of...

Surface to subsurface correlation of the Middle-Upper Triassic Shublik Formation within a revised sequence stratigraphic framework
Recent work on cores and outcrops of the Middle-Upper Triassic Shublik Formation has facilitated surface to subsurface correlation of depositional sequences across the Alaska North Slope. Five transgressive-regressive depositional sequences have been defined within three large-scale stratigraphic units. Outcrop spectral gamma-ray (GR) profiles...

Element cycling in the Middle-Late Triassic Shublik Formation: Mineralization vs. recycling of biolimiting nutrients in an unconventional resource play
The Triassic Shublik Formation in northern Alaska is one of the major source rocks in North America, having generated much of the petroleum in Prudhoe Bay and associated fields. The middle Shublik Formation, the focus of this study, is a highly phosphatic, organic-rich carbonate mudstone interval. Apatite cements can occur as phosphatic peloids,...

The Upper Cretaceous Eagle Ford Group displays significant lateral and vertical geochemical variability. Much of the work on the Eagle Ford Group has been focused southwest of the San Marcos arch. To more fully characterize the Eagle Ford across the entire region, a thermally immature drill core was acquired north of the San Marcos arch that...
