The database is designed to be a convenient resource for any member of the public to easily access source rock data from across the Gulf Coast region, circumventing the need for extensive, time-consuming literature searches.

This application provides an overview of oil and gas well history of the United States, from 1880 to September 1, 2022. Well history data is aggregated into 10-mile squares indicating the total number of wells and counts of wells classified as oil, gas, dry, injection, hydraulically fractured, and/or horizontal wells. 

The National Petroleum Reserve, Alaska, (NPRA) Legacy Data Archive represents one of the largest geological and geophysical data sets held by the U.S. Geological Survey. Two exploration programs by the U.S. Navy and USGS collected over 12,000 line miles of seismic data and drilled 28 wells.  These programs generated a vast amount of data, analyses, and documents, much of which is presented h

Since January of 1989, the U.S Geological Survey Energy Resources Program Geochemistry Laboratory Database (EGDB) has grown to contain the analytical data for over 200,000 samples worldwide. The EGDB contains chemical analysis data for crude oil, natural gas, coal, water, and rock samples analyzed by the USGS Energy Resources Science Center’s Geochemistry Laboratory, or by contracted-service

The content available here represents an archive of a publication released in 1994 entitled International Phase of Ocean Drilling:  Seismic Line 1 Demultiplexed Data, Cape Hatteras to Mid-Atlantic Ridge.
