METHOD FOR DEVELOPING FLOODED OIL DEPOSITS WITH STRATA OF DIFFERENT PENETRABILITY AND NONUNIFORM IN DIFFERENT ZONES Russian patent published in 1995 - IPC

Abstract RU 2046182 C1

FIELD: oil production. SUBSTANCE: pumping water in pressure well, margining agent that increases filtering resistance of porous medium followed by water pumping in, and extracting stratum fluids through production wells. Water pumping in before agent margining is performed on turning off production wells with amount assuring creation of elastic reserve of poor-penetrable stratum portion. Pumping in agent margin is carried out at turned on production wells with floodability above medium level. EFFECT: development of flooded oil wells.
