A horizontal production well is located in the lower portion of a heavy viscous oil-bearing reservoir. A vertical injection well is located in the upper portion of the reservoir. Oxygen-enriched gas is injected down the injector well and ignited in the upper portion of the reservoir to create a comb ...

Paul S Northrop, James L Wilson: Method for producing low permeability reservoirs using a single well. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, January 3, 1995: US05377756 (248 worldwide citation)

A method for recovering connate fluids (e.g. oil) from a low permeability subterranean reservoir (e.g. diatomite) through a single wellbore. Upper and lower intervals are fractured from the wellbore that the fractured intervals only partially overlap, thereby leaving a partial, natural barrier forme ...

Alfred R Jennings Jr, Ibrahim S Abou Sayed: Oil recovery optimization using a well having both horizontal and vertical sections. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, August 23, 1994: US05339904 (243 worldwide citation)

A steam, carbon dioxide, or solvent injection method is used in combination with a cased well completed to have an upper vertical section, a lower vertical section and a horizontal section which connects the two vertical sections. Steam, carbon dioxide, or solvent is injected down tubing in the well ...

Paul S Northrop, Robert S Timmer: Method for producing low permeability reservoirs using steam. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, May 16, 1995: US05415231 (235 worldwide citation)

A method for recovering hydrocarbons (e.g. oil) from a low permeability subterranean reservoir of the type comprised primarily of diatomite. A first slug or volume of a heated fluid (e.g. 60% quality steam) is injected into the reservoir at a pressure greater than the fracturing pressure of the rese ...

Christopher Burcham, Robert E Fast, Anthony S Murer, Paul S Northrop: Oil recovery by enhanced imbitition in low permeability reservoirs. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, Charles A Malone, May 2, 1995: US05411086 (196 worldwide citation)

A method for enhanced oil recovery from a low permeability diatomaceous reservoir by imbibition is described. In this method, oil is displaced from a single injection well, or series of injection wells into a single producer or series of producing wells by a combination of applied fluid pressure, pl ...

Alfred R Jennings Jr, Eve S Sprunt: Unique method of hydraulic fracturing. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, Charles A Malone, April 4, 1995: US05402846 (188 worldwide citation)

An improved method for hydraulically fracturing a formation or reservoir where a thermo-setting gellable mixture is utilized. This thermo-setting mixture is foamed either at the surface or in situ under fracturing pressures and conditions. The mixture and carrier fluid is of a composition such that ...
