  • CO.sub.2 removal from hydrocarbon gas in water bearing underground reservoir
    Patent number: 4187910
    Abstract: A process for decreasing the CO.sub.2 content of hydrocarbon gas by injecting a hydrocarbon gas containing CO.sub.2 into a water bearing zone of an underground formation and producing hydrocarbon gas from a collection point in the underground formation removed from the injection point.

  • Reservoir treatment by injecting mixture of CO.sub.2 and hydrocarbon gas
    Patent number: 3995693
    Abstract: A process is provided in which hydrocarbon gas containing CO.sub.2 is injected into an oil containing reservoir as an aid in recovering oil from the reservoir. Oil can be produced from at least one production well in said reservoir while hydrocarbon gas containing less CO.sub.2 than the injected mixture of hydrocarbon gas and CO.sub.2 can be recovered from production wells other than the oil producing well. Backflowing of the injection well produces a gas containing more CO.sub.2 than the gas originally injected. The method provides an in situ separation of CO.sub.2 from hydrocarbon gas.
