METHOD OF DEVELOPING NONUNIFORM OIL POOL Russian patent published in 1996 - IPC

Abstract RU 2065936 C1

FIELD: oil and gas production. SUBSTANCE: in the late stage of developing oil pool, a productive well is found, to which working medium from injection well comes with highest velocity. A polymer material solution is pumped in simultaneously through injection well and preset well. Volume of solution pumped through the latter is 15-25% that of solution volume pumped through the former. After polymer material solution is pumped in, the injection wells are pumped through with working medium, and crude oil is produced through productive wells. EFFECT: increased oil production.
