摘要： Disclosed herein are methods for extracting a kerogen-based product from subsurface (oil) shale formations. These methods rely on chemically modifying the shale-bound kerogen using a chemical oxidant so as to render it mobile. The oxidant is provided to a formation fluid in contact with the kerogen in the subsurface shale. An alkaline material is also provided to the formation fluid to mobilize organic acids which are produced during oxidation of the kerogen. A mobile kerogen-based product which includes the organic acids is withdrawn from the subsurface shale formation and further processed to isolate the organic acids contained therein. These organic acids are valuable as hydrocarbon products for creating commercial products and a portion of these organic acids can also be used in the process for extracting the kerogen-based product from the subsurface shale formation.

摘要： Disclosed herein are methods for extracting an organics component from subsurface shale formations comprising kerogen and an extractible organics component in an inorganic matrix. Among other factors, these processes are based on the discovery that to more easily access the kerogen in oil shale, it is helpful to first remove the extractible organics component from the subsurface shale formation. The methods utilize a hydrocarbon solvent to at least partially solubilize the extractible organics component. The extractible organics component can be isolated and upgraded to produce useful products. The presently disclosed processes are more environmentally benign, more economical, and more efficient in producing commercial products and in providing access to kerogen.

The oxidant is provided to a formation fluid in contact with the kerogen in the subsurface shale. A mobile kerogen-based product which includes the organic acids is withdrawn from the subsurface shale formation and processed to isolate the organic acids contained therein. An exemplary method for isolating the acids includes treating the mobile kerogen-based product such that at least a portion of the organic acids form a separate phase from the mobile kerogen-based product. The organic acids may further be extracted from the mobile kerogen-based product using an organic extraction fluid.
