Abstract
Methods of extracting a hydrocarbon-based product from subsurface (oil) shale formations are provided. These methods rely on the use of an extraction fluid comprising pentane for facilitating the production of a mobile hydrocarbon-based product when the pentane contacts hydrocarbons in subsurface shale. The contacting process, and the subsequent process of recovering the mobile hydrocarbon-based product, is further enhanced by the methods of fracturing and/or rubblizing portions of the shale formation, so as to enhance their fluid permeability.
