The Green River Formation — an assemblage of over 1,000 feet of sedimentary rocks that lie beneath parts of Colorado, Utah, and Wyoming — contains the world's largest deposits of oil shale. The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated. This website contains The oil shale in the Green River Formation was Oil and gas are produced from the shore facies of formed mainly in two large lakes-Lake Uinta in the Green River Formation at several fields in the Colorado and Utah, and Lake Gosiute in Wyoming. northern part of the Uinta Basin. Oil shale in the Green River Formation is found in five sedimentary basins namely, Green River, Uinta, Piceance Creek, Sand Wash and Washakie. The first three have undergone some significant exploration and attempts to commercialize the oil shale reserves since the 1960s. The Green River Formation includes deposits from two large lakes which covered an estimated area of over 65,000 square kilometres (25,100 sq mi) during the Early to Middle Suggested citation: U.S. Geological Survey Oil Shale Assessment Team, 2011, Oil shale resources of the Eocene Green River Formation, Greater Green River Basin, Wyoming, Colorado, and Utah: U.S. Geological Survey Digital Data Series DDS–69–DD, 6 chapters, pages variable.
The Green River Formation is an Eocene rock formation on the eastern side of the Rocky Mountains. It records sediment from a group of intermountain lakes. Its fine fossils make this a lagerstätte, a place of exceptional preservation. The various fossil beds of the Green River Formation span a 5 million year period, dating to between 53.5 and 48.5 million years ago. During this period the climate moved from the moist early Eocene climate and the slightly drier mid-Eocene. The sediments are Part 1: Shale Oil Potential of the Green River Formation, Uinta Basin, Utah The GRF in the Uinta Basin has been studied for over 50 years since the first hydrocarbon discoveries. However, those studies focused on the many conventional sandstone reservoirs currently producing oil and gas. These deposits are found exposed around the Uinta Basin’s rim in the Green River Formation—also a major oil and gas producer in the subsurface of the basin. Shale is a fine-grained sedimentary rock composed of mud containing clays and silt-size particles of other minerals.

Huge amounts of water are required in the oil shale production process. The largest deposit of oil shale in the world is found in the Green River basin of Oil shale is a fine grained sedimentary rock formed from the compaction and 3 Jul 2017 In-place oil shale resources of the Eocene Green River Formation were compiled and reported in the recent U.S. Geological Survey assessment.

Total in-place resources for the three assessed units in the Green River Formation are: (1) Tipton Shale Member, 362,816 million barrels of oil (MMBO), (2) Wilkins Peak Member, 704,991 MMBO, and (3) LaClede Bed of the Laney Member, 377,184 MMBO, for a total of 1.44 trillion barrels of oil in place. About 72 percent of this oil shale is located within the Green River Formation in Colorado, Utah, and Wyoming and lies beneath federal lands managed by the Department of the Interior s Bureau of Land Management, making the federal government a key player in its potential development. Even though the amount is much lower than the 800 billion barrels of recoverable oil in the Green River formation, the difference is that the Bakken is actually producing oil. And when it comes to the Bakken, we're talking about light, sweet crude.
