OIL FIELDS DEVELOPMENT METHOD Russian patent published in 2010 - IPC E21B43/20 

FIELD: oil-and-gas industry.

SUBSTANCE: invention related to oil field development. Method includes dislocation of production and injection wells, pumping a driving fluid through injection wells and product withdrawal through production wells. Additionally define product flooding velocity. Then at the late stage of oil field development, in dependence of the product flooding velocity during production process, gradually transfer production wells, which was flooded at first and which product water content increased 15-20% a year into injection, or execute wells killing. The transfer well of the second group, which product water content increased 5-15% a year into injection, with preliminary pumped in ticked driving medium. Then transfer well of the third group, located closer to production wells constrict rows and oil stagnation zones, which product water content increased 1-5% a year.

EFFECT: oil fields development efficiency increase due to gradual transfer flooded production wells into injection, oil surface efficiency increase, cost cutting due corresponding to water production decrease, pumping it driving medium.
