The U.S. Geological Survey (USGS) recently completed a comprehensive assessment of in-place oil in oil shales of the Eocene Green River Formation of the Piceance Basin of western Colorado (fig. 1; USGS FS 2009-3012). This 2009 assessment is based on the considerable amount of data that has been collected since the previous USGS in-place assessment was published in 1989. Much of the new data that were previously company confidential were since donated by industry after interest in developing oil shale decreased in the 1980s.
This page provides access to data that supports the Oil Shale Assessment and was released as part of the 2009 update of OFR 98-483, (introduction available here (2.78 MB, Adobe Acrobat))
