PROCEDURE FOR ISOLATION OF WATER-ENCROACHED SECTIONS OF OIL RESERVOIR Russian patent published in 2011 - IPC E21B33/13 C09K8/50

Abstract RU 2426864 C1

FIELD: oil and gas production.

SUBSTANCE: procedure for isolation of water-encroached sections of oil reservoir consists in pumping down water limiting composition into it. As such there is used suspension consisting of one part of active silt and nine parts of sewage water and with active weight 1.15:1.25 g/cm³. Suspension is made by means of mixing active silt and sewage water in primary sumps of treatment facilities - aero tanks with simultaneous purification of water in them to environmental safe composition. Also, withdrawal of such suspension for pumping it down into an oil reservoir is performed after its inflow from primary sumps into secondary ones.

EFFECT: raised efficiency of oil yield of water-encroached sections of oil reservoir.
