Winston R Shu: Lowering CO.sub.2 MMP and recovering oil using carbon dioxide. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Lawrence O Miller, April 30, 1985: US04513821 (41 worldwide citation)

Oil is recovered by a CO.sub.2 miscible oil recovery method in which the CO.sub.2 minimum miscibility pressure of the oil-containing formation is lowered by injecting a coolant into the formation. The formation is then pressurized to a pressure at least that of the reduced CO.sub.2 minimum miscibili ...

Winston R Shu: Method for transporting viscous crude oils. Mobil Oil Corporation, Alexander J McKillop, James F Powers Jr, Lawrence O Miller, December 13, 1983: US04420008 (40 worldwide citation)

Viscous crude oil is mixed with an oil diluent having a relatively low viscosity and the resulting mixture having a predetermined viscosity and flow rate is pumped in a pipeline to a point of use. The flow rates of the viscous crude oil and the diluent are controlled with the aid of a digital comput ...

Winston R Shu: Viscous oil recovery method. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Malcolm D Keen, August 21, 1984: US04466485 (28 worldwide citation)

A subterranean, viscous oil-containing formation is penetrated by at least one injection well which extends downwardly from the earth's surface to the formation and then extends a predetermined distance through the formation in a generally horizontal direction. The horizontal section of the injectio ...

Paul Shu, Winston R Shu: Process for selective placement of polymer gels for profile control in thermal oil recovery. Mobil Oil, Alexander J McKillop, Charles J Speciale, Lawrence O Miller, February 14, 1989: US04804043 (26 worldwide citation)

High permeable thermally fluid swept zones in an oil containing formation are selectively plugged by a high temperature selective gel-forming solution without plugging the less permeable unswept portion of the formation. Ungelled solution in the less permeable unswept portion of the formation in the ...
