About Oil Shale and Oil Sands
The GSI in-situ process was specifically designed to extract gaseous hydrocarbon products from oil shale. Oil shale is an organic-rich fine-grained sedimentary rock, containing significant amounts of a compound known as kerogen, which can be converted into an array of hydrocarbon products.
Oil Shale is not related to Shale Gas (e.g. The Marcellus Shale) where fracking is used to help extract the only product, natural gas or Shale Oil (e.g. The Bakken Shale), where oil in shale rock is extracted also using fracking.
Recent estimates set the total recoverable world oil shale resources at enough to produce 2.8 to 3.3 trillion barrels of oil. Approximately 65% of the world’s oil shale resources are located in the Green River Formation in northwestern Colorado, northeastern Utah and southwestern Wyoming. The majority of the oil shale in the Green River Basin is comprised of marlstone.
The GSI in-situ technology can also be used to extract oil from the bitumous tar/oil sands. There are more than 50 tar sands deposits located in eastern Utah, containing an estimated 12 to 19 billion barrels of oil.
Additional Information and Resources:
Oil shale deposits have been identified in some 40 countries. Current estimates of recoverable worldwide oil shale resources range from 2.8 - 3.2 trillion barrels (more than twice current proven conventional oil reserves). Recoverable oil from oil shale in the U.S. is estimated between 800 billion to 1.2 trillion barrels by the USGS.
