Winston R Shu, Kathy J Hartman: Viscous oil recovery method. Mobil Oil Corporation, Alexander J McKillop Michael G Gilman Lawrence O Miller, May 29, 1984: US04450911 (20 worldwide citation)

In a thermal method for the recovery of oil from a subterranean, viscous oil-containing formation, steam in an amount ranging from 0.3 to 0.5 pore volume and an injection rate within the range of 4.0 to 7.0 bbl/day/ac.-ft. is injected into the formation via an injection well completed in the lower 5 ...

Winston R Shu, Kathy J Hartman: Viscous oil recovery method. Mobile Oil Corporation, Alexander J McKillop, Michael G Gilman, Stanislaus Aksman, July 1, 1986: US04597443 (19 worldwide citation)

In a thermal method for the recovery of oil from a subterranean, viscous oil-containing formation, a predetermined amount of steam in an amount not greater than 1.0 pore volume and an injection rate of 4 to 7 barrels of steam (cold water equivalent) per day per acre-foot of formation is injected int ...

Kathy J Hartman, Winston R Shu: Miscible oil recovery process. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Charles A Malone, July 7, 1987: US04678036 (12 worldwide citation)

A miscible flooding process for oil recovery employs a multiple contact miscible solvent such as carbon dioxide and an additive such as butane which lowers the minimum miscibility pressure of the oil/solvent system. The additive is injected in a slug with a solvent, preferably followed by a slug of ...
