USGS Energy Geochemistry Database
USGS Energy Geochemistry Database

Rock-Eval pyrolysis, Geochemistry, Coal Quality, ...
Since January of 1989, the U.S Geological Survey (USGS) Energy Resources Program Geochemistry Laboratory Data Base has grown to contain the analytical data for over 200,000 samples worldwide. The Energy Geochemistry Data Base (EGDB) contains chemical analysis data for crude oil, natural gas, coal, water, and rock samples analyzed by the USGS Energy Resources Team's Geochemistry Laboratory, or by contracted-service laboratories. Data was also obtained from the literature and unpublished public domain sources. The sample types included are primarily rock, coal, oil, and gas. This information is used by the USGS for worldwide energy resource assessments and is periodically released to the public. Analytical data within the EGDB includes Rock-Eval pyrolysis, organic mass spectrometry, vitrinite reflectance, gas chromatography, stable carbon isotopes, inductively coupled plasma, inductively coupled plasma mass spectrometry, mercury analysis and a number of other related geochemistry analyses that, in some instances, predate the EGDB. Throughout the years the Energy Program scientists have utilized these data to not only develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation. but also as a tool to assess the oil and gas potential for sedimentary basins in both national and international settings.
