  • Subterranean capture of produced gas lost in gas enhanced hydrocarbon recovery
    Patent number: 12716337
    Abstract: Subterranean gas capture wellbores are used to capture lost produced gas. Produced gas can be injected into a subterranean for gas enhanced hydrocarbon recovery and rise in the subterranean formation toward a production wellbore. A first portion is effective for enhanced hydrocarbon recovery and a second portion rises past the production wellbore to become the lost produced gas that is converted to captured produced gas in the subterranean gas capture wellbore. The captured produced gas can then flow in the subterranean gas capture wellbore to the surface for recovery.
    Type: Grant
