Bureau of Land Management estimating that the Green River deposits alone contain a technically recoverable resource of hundreds of billions of barrels of oil equivalent. Surface retorting involves mining the rock and then heating it in large above-ground vessels called retorts.
Engineering Solutions for Shale Extraction: Innovative Techniques and Processes
The scale of these resources is substantial, with the U. These processes involve drilling a network of wells into the oil shale formation.
One method, known as electrical resistive heating, passes an electrical current through the rock to generate heat, while another uses downhole combustion to create a thermal front that moves through the formation. The processing required to convert kerogen into oil is energy-intensive and capital-heavy, making it significantly more expensive than conventional extraction.

When subjected to heat in the absence of oxygen, this kerogen decomposes to produce shale oil, a synthetic crude oil that can be further refined into usable fuels. When oil prices are low, the high break-even point for oil shale projects makes them financially unattractive.
