METHOD FOR DEVELOPMENT OF WATER-FLOATING GAS OR GAS-CONDENSATE DEPOSITS Russian patent published in 1998 - IPC

FIELD: gas production industry. SUBSTANCE: this is intended for increasing amount and speed of gas recovery from deposits. Method implies drilling of bore-holes and opening of productive intervals with subsequent recovery of gas from producing wells. Preliminary recovery of gas from wells is performed at production rate in excess of initial critical waterless production rate. Recorded is breakthrough of water cone into well and permitted is change of well production rate as to gas up to reaching preset gas-water factor. After that, gas recovery is carried out at maintaining value of determined gas factor through varying depression brought to bear on bed. This allows for increasing final coefficient of gas recovery, intensifying production rates of wells as to gas, and prolonging period of profitable gas production. EFFECT: higher efficiency. 3 dwg
