摘要： The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on fracturing and/or rubblizing portions of said formations so as to enhance their fluid permeability, and wherein such methods further rely on chemically modifying the shale-bound kerogen so as to render it mobile. The present invention is also directed at systems for implementing at least some of the foregoing methods. Additionally, the present invention is also directed to methods of fracturing and/or rubblizing subsurface shale formations and to methods of chemically modifying kerogen in situ so as to render it mobile.

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.

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 utilizing electrokinetic-induced migration. An electric field is generated through at least a portion of the kerogen rich zone to induce electrokinetic migration of the oxidant. A mobile kerogen- based product, that includes reaction products of kerogen conversion, is urged toward a production well utilizing electrokinetic-induced migration, and withdrawn from the subsurface shale formation. An electric field generated through at least a portion of the kerogen rich zone can also be utilized to induce migration of catalysts or catalyst precursors.

摘要： Disclosed herein is a process for preparing transportation fuel and optionally a middle distillate, a diesel fuel, a heating oil, a jet fuel, a kerosene, an aviation gasoline, a gasoline fuel, or a lubricant base oil. The process includes the steps of (a) producing a naturally occurring aqueous fluid containing greater than 1 wt. % soluble carboxylic acids; (b) isolating at least a portion of the organic acids from the naturally occurring aqueous fluid; and (c) upgrading the isolated carboxylic acids. The step of upgrading the isolated carboxylic acids can include at least one of hydrotreating, hydrocracking, isomerization, esterification and FCC cracking. The aqueous fluid can then be used in processes for recovery of a mobile kerogen based product. Also disclosed herein is a process for preparing a biofuel comprising the organic acids isolated from naturally occurring aqueous fluid.

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. 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. The isolated organic acids can be upgraded by a reaction process that make the products suitable as refinery feedstocks, fuel or lubricant blendstocks, reaction intermediates, chemical feedstocks, or chemical intermediate blendstocks.
