PETROLEUM DEPOSIT DEVELOPMENT PROCESS Russian patent published in 2008 - IPC E21B43/24 E21B36/04 

FIELD: oil and gas industry.

SUBSTANCE: invention is referred to a petroleum industry and can be applied at development of reservoir with a high-viscosity oil or bitumen. It provides efficiency upgrading of warm-up of a bottom-hole zone of a hole, oil viscosity decreasing and increasing of a reservoir oil recovery. Essence of invention: the method includes electric warm-up of a productive strata and bleeding of oil by holes. According to the invention a breaking of electric connection between a part of a casing string in the range of productive strata and other parts of a casing string will be organised in a hole. The tubular annulus between a tubing string and a casing string is space filled by dielectric fluid. Tubing string isolation from down hole equipment, pipe lines on a hole and casing string mouth is organised. An electric contact between a tubing string and a casing string in the range of productive strata is provided. An electric current is fed to a tubing string.

EFFECT: efficiency upgrading of warm-up of a bottom-hole zone of a hole, oil viscosity decreasing and increasing of a reservoir oil recovery.
