Eugene Ostapovich, Farrokh N Pebdani: Method for enhanced oil recovery through a horizontal production well in a subsurface formation by in-situ combustion. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, May 18, 1993: US05211230 (262 worldwide citation)

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 ...

Farrokh N Pebdani: Enhanced oil recovery for oil reservoir underlain by water. Mobil Oil Corporation, Alexander J McKillop, Charles J Speciale, Lawrence O Miller, October 9, 1990: US04961467 (17 worldwide citation)

A method for recovering viscous oil from a subterranean, viscous oil-containing formation underlain by a water zone. Steam is injected into the formation via the injection well at the oil/water contact and oil is recovered from the formation until steam breakthrough occurs at the production well the ...

Matthew G McNaughton, Eugene Ostapovich, Farrokh N Pebdani: Apparatus for fluidizing formation fines entrained in formation fluids entering a production well penetrating an oil-bearing formation. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, May 11, 1993: US05209293 (3 worldwide citation)

A production well penetrating a subsurface oil-bearing formation utilizes perforations in well casing through which formation fluids enter the well. Production tubing extends from the surface of the earth to a position below such perforations. A pump is positioned at the lower end of the tubing for ...
