  • Method and system for extraction of liquid hydraulics from subterranean wells
    Patent number: 6443229
    Abstract: A method and system for tertiary or enhanced oil recovery from a subterranean liquid hydrocarbon or oil wells is described. The method uses packers (104, 105, 204, 205, 304, 305, 305A, 305B) or angled wells (401) in order to force the gas down into the oil bearing strata (502) from a gas containing strata (501). The result is increased production of oil since the gas is forced downward over a large horizontal area between the gas containing strata and oil bearing strata.
