METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2003 - IPC

FIELD: oil producing industry; applicable in development of oil pools with bottom water. SUBSTANCE: method includes building-up of pressure differential on formation and withdrawal of product through producing wells. In development of oil pool with carbonate reservoirs having vertical fractures, producing formation is subject to intensifying treatment through producing wells. In oil withdrawal, bottomhole pressures in these wells are set with value of pressure differential at absolute elevation of water-oil contact of 0.5-1.5 Mpa for creation of conditions of uniform rise of water level in oil pool. EFFECT: reduced rate of well water encroachment and increased water-free oil production period. 1 ex
