OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2012 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: method involves oil withdrawal through production wells, ignition of oil formation, pumping of air to pressure wells, and after withdrawal of 45-50% of extracted oil resources pumping-in of hot water not less than 60°C with the density 1.000-1.005 g/cm³ through injection well with the highest formation temperature in the center of the specified area of the developed deposit, heat transfer from zone of high temperatures of deposit to zones of its low temperatures by covering the areas exceeding the sizes of the chosen section. Hot gas is pumped-in together with the hot water. Gas is represented by gaseous products resulting from the process of oil formation burning. The ratio of water and gas pumping volume is defined due to the condition of production wells flowing.

EFFECT: increase of oil production, reduction of energy consumption, decrease of hazardous substances emission into the atmosphere.
