USGS Publication: Open-File Report 2012–1151
The Organic Petrology Laboratory (OPL) of the U.S. Geological Survey (USGS) Eastern Energy Resources Science Center in Reston, Virginia, contains several thousand processed coal sample materials that were loosely organized in laboratory drawers for the past several decades.

Outside Publication: AAPG Search and DiscoveryMany oil and gas reservoirs in Tertiary strata of southern Louisiana are located close to the interface between a sand-rich, normally pressured sequence and an underlying sand-poor, overpressured sequence. This association, recognized for many years by Gulf Coast explorationists, is revisited here because of its relevance to an assessment of undiscovered oil and gas potential in the Gulf Coast of Louisiana.

USGS Publication: Open-File Report 2012-1046A one-dimensional petroleum system modeling study of Paleogene source rocks in Louisiana was undertaken in order to characterize their thermal history and to establish the timing and extent of petroleum generation. The focus of the modeling study was the Paleocene and Eocene Wilcox Formation, which contains the youngest source rock interval in the Gulf Coast Province.

Outside Publication: Journal of Marine and Petroleum Geology
The scientific results of the 2009 Gulf of Mexico Joint Industry Program Leg II Logging-While-Drilling (LWD) expedition have been published as a special issue of the Journal of Marine and Petroleum Geology (Volume 34, Issue 1).

USGS Publication: Fact Sheet 2012–3003
Using a geology-based assessment methodology, the U.S. Geological Survey assessed means of (1) 141 million barrels of oil (MMBO), 502 billion cubic feet of natural gas (BCFG), and 16 million barrels of natural gas liquids (MMBNGL) in the conventional Eagle Ford Updip Sandstone Oil and Gas Assessment Unit (AU); (2) 853 MMBO, 1,707 BCFG, and 34 MMBNGL in the continuous Eagle Ford Shale Oil AU; and (3) 50,219 BCFG and 2,009 MMBNGL in the continuous Eagle Ford Shale Gas AU in onshore lands and State waters of the Gulf Coast.

USGS Publication: Open-File Report 2011–1261
Coal exploration drill-hole data from over 24,000 wells in 10 States are discussed by State in the chapters of this report, and the data are provided in an accompanying spreadsheet.

Outside Publication: AAPG Discovery Series
For eight years (1995-2003), geologic, geochemical, and resource information was collected and compiled for the five major coal-producing regions of the United States: the Appalachian Basin, Illinois Basin, Northern Rocky Mountains and Great Plains, Colorado Plateau, and the western part of the Gulf of Mexico Coastal Plain (Gulf Coast) region. This volume contains the assessment results for the Gulf of Mexico Coastal Plain region.

USGS Publication: Fact Sheet 2011–3046Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 957 million barrels of undiscovered oil, 3.6 trillion cubic feet of undiscovered natural gas, and 363 million barrels of undiscovered natural gas liquids in the Austin Chalk and Tokio and Eutaw Formations in onshore lands and State waters of the Gulf Coast.

USGS Publication: Open-File Report 2011-1086For the largest producing natural gas fields in the onshore Gulf of Mexico Basin, the relation between temperature versus depth was investigated. Prolific natural gas reservoirs with the highest temperatures were found in the Upper Cretaceous downdip Tuscaloosa trend in Louisiana.
The Gulf Coast Region is a physiographic province extending from Texas to Florida and encompasses the coastal plain, low hills, and deltas of the Gulf of Mexico. This is a geologically stable area characterized by low relief terraces extending to the continental shelf. Sediments consist of coastal plain deposits and thick land-derived sediments prograding from the Mississippi River delta system; ultimately transitioning to evaporite and carbonate deposits offshore. Coastlines exhibit wave and delta dominated features and landforms such as barrier islands, bays, and marshes. The Mississippi River also supports a diverse economy in the region. A large percentage of the present and future energy resources of the United States are located in the Gulf Coast Region, highlighting the importance for energy research and assessments. This web site provides access to the Energy Resources Program research activities and products within the Gulf Coast Region.

The USGS has completed several assessments of the Gulf Coast. This information is summarized on the Oil and Gas Assessment Gulf Coast page.
The National Coal Resource Assessment (NCRA) project was a multi-year effort by the U.S. Geological Survey (USGS) Energy Program to identify, characterize, and assess the coal resources that will supply a major part of the Nation’s energy needs during the next few decades. NCRA data and publications are available on the NCRA Gulf Coast page.
There are coalbed methane assessments for the Gulf Coast currently available.
USGS has created a comprehensive geopressure-gradient model of the regional pressure system spanning the onshore and offshore portions of the Gulf of Mexico, USA..
This series of five maps characterizes the subsurface pressure system of southern Louisiana, including the associated State and Federal waters.
