Shale oil is a type of liquid hydrocarbon derived from oil shale, a sedimentary rock rich in organic compounds called kerogens. To extract this oil, the rock undergoes unconventional processes, such as heating or hydraulic fracturing (fracking), which involves injecting a high-pressure mixture of water, sand, and chemicals. While shale oil extraction offers significant reserves, particularly ...
