Closmann Philip J: Spreading-fluid recovery of subterranean oil. Shell Oil Company, Coryell H W, April 16, 1974: US3804169 (206 worldwide citation)

In a process for producing shale oil by circulating fluid through a cavity that contacts a subterranean oil shale, the cavity is extended laterally into both an injection well and a plurality of surrounding productions wells and the fluid is circulated at a rate causing the velocity within the cavit ...

Closmann Philip J, Suman Jr George O: Method for the recovery of oil from oil shale. Shell Oil Company, Coryell H W, April 16, 1974: US3804172 (204 worldwide citation)

Shale oil is recovered by forming a subterranean cavern that contacts an oil shale, packing the cavern with solid granules and removing organic and inorganic solids from the oil shale by circulating fluid from a surface location, into contact with the oil shale, through a mass of packed granules, an ...

Closmann Philip J: Method of producing shale oil from an oil shale formation. Shell Oil Company, May 11, 1971: US3578080 (179 worldwide citation)

A method of producing shale oil from a subterranean oil shale formation by exploding a relatively high energy explosive device therein thereby forming a chimney of rubble within the formation having fractures extending from the chimney into the formation. A plurality of spaced wells are extended int ...

Closmann Philip J, Phocas Dionysios M: Process for horizontally fracturing subsurface earth formations. Shell Oil Company, October 19, 1971: US3613785 (39 worldwide citation)

Horizontal fractures are formed in a subsurface earth formation which tends to fracture vertically at the naturally occurring formation temperature by a process which includes the steps of extending at least one well borehole into the formation, generating a vertical fracture by pressurizing said bo ...

Closmann Philip J: Heating through fractures to expand a shale oil pyrolyzing cavern. Shell Oil Company, June 10, 1975: US3888307 (26 worldwide citation)

In a process for recovering shale oil by injecting and producing fluid into and out of a rubble-containing cavity in an otherwise substantially non-porous and impermeable subterranean oil shale formation, hot gas is circulated into and out of the cavity through spaced horizontal fractures to preheat ...

Closmann Philip J: Vertically expanded structure-biased horizontal fracturing. Shell Oil Company, May 20, 1975: US3884303 (12 worldwide citation)

A subterranean earth formation is fractured horizontally by connecting a vertically expandable structure above and below a selected depth within the earth formation, applying a vertical expanding force to the structure so that the applied force reduces the vertical compressive stress within the eart ...
