METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 1997 - IPC

FIELD: oil production industry. SUBSTANCE: according to method, wells are arranged in compliance with geological structure of deposit. Working agent is injected through injection wells and oil is recovered through producing wells with subsequent additional prospecting for new deposits. Deposit is developed in mode of reducing bed pressure. Additional well is drilled in zone of lithologic displacement beyond perimeter of oil saturation. Bed pressure and reservoir permeability are determined in producing bed interval. At spasmodic reduction of bed pressure and multiply increased permeability in new well, conclusion is drawn about occurrence of new deposit. Zone of drilling new wells is widened beyond known oil-bearing contour. Arrangement of wells and development operations are performed according to geological structure of new deposit. EFFECT: high efficiency.
