OIL RESERVOIR DEVELOPMENT METHOD (VARIANTS) Russian patent published in 2005 - IPC

Abstract RU 2267009 C2

FIELD: oil industry, particularly development of oil reservoir penetrated by horizontal wells.

SUBSTANCE: method involves drilling wells; injecting working agent through a number of injection wells and recovering oil through a number of production wells arranged in parallel to injection ones, in dependence of oil viscosity. In above method vertical or horizontal wells are bored. If oil mobility index M≥2.5 vertical injection and horizontal production wells are bored. If oil mobility index is 0,4<M<2.5 horizontal wells are drilled. If oil mobility index M≤0.4 horizontal injection and vertical production wells are bored.

EFFECT: increase efficiency.
