Gulf Coast Geologic Energy Assessments

View Assessments

The Gulf Coast Geologic Energy Assessments and Research (GEAR) project assesses and characterizes undiscovered, technically recoverable domestic petroleum resources. It focuses on the onshore and State waters portion of the Gulf Coast basin. The primary goal of this project is to meet the needs of Congress and other stakeholders for timely and robust assessments of petroleum resources in the Gulf Coast region. The Gulf Coast GEAR project also conducts associated research on the processes that impact the formation, accumulation, occurrence, and alteration of hydrocarbon energy resources.

Biogenic origin of coalbed gas in the northern Gulf of Mexico Coastal Plain, U.S.A Biogenic origin of coalbed gas in the northern Gulf of Mexico Coastal Plain, U.S.A

New coal-gas exploration and production in northern Louisiana and south-central Mississippi, Gulf of Mexico Basin, is focused on the Wilcox Group (Paleocene–Eocene), where the depth to targeted subbituminous C to high volatile C bituminous coal beds ranges from 300 to 1680 m, and individual coal beds have a maximum thickness of about 6 m. Total gas content (generally excluding residual...

Assessment of undiscovered oil and gas resources in Tertiary strata of the Gulf Coast, 2007 Assessment of undiscovered oil and gas resources in Tertiary strata of the Gulf Coast, 2007

Using a geology-based assessment methodology, the U.S. Geological Survey estimated a mean of 113.7 trillion cubic feet of undiscovered natural gas, a mean of 690 million barrels of undiscovered oil, and a mean of 3.7 billion barrels of undiscovered natural gas liquids in onshore lands and State waters of the Gulf Coast.

Organic geochemistry of sediments in nearshore areas of the Mississippi and Atchafalaya Rivers: I. General organic characterization Organic geochemistry of sediments in nearshore areas of the Mississippi and Atchafalaya Rivers: I. General organic characterization

This report presents results on the general organic characteristics of sediment cores collected from the coastal zone of the Mississippi River system, including distributions of the important nutrient elements (C, N, P, and S). This was part of a larger study conducted from 2001-2005 to examine the delivery of sediment-associated contaminants to the Gulf of Mexico by the Mississippi...

Results from Coalbed Methane Drilling in Winn Parish, Louisiana Results from Coalbed Methane Drilling in Winn Parish, Louisiana

A coalbed methane (CBM) well in Winn Parish, Louisiana, named CZ Fee A No. 114, was drilled by Vintage Petroleum, Inc., in January 2004. The CZ Fee A No. 114 CBM well was drilled to a total depth of 3,114 ft and perforated at 2,730-2,734 ft in a Wilcox Group (Paleocene-Eocene) coal bed. Analytical data from the drilling project have been released by Vintage Petroleum, Inc., and by the...
