  • Gas and oil production
    Patent number: 6805194
    Abstract: A process for in situ gasification of mineral oil in a subterranean formation comprises running a tool having a controllable thermal device therein from a surface production facility down to the subterranean formation, bringing said tool into operational proximity with the mineral oil in said subterranean formation, and activating the tool to operate the thermal device within a predetermined temperature range to generate gases or oily vapours from said mineral oil, which permits either an enhanced oil recovery (EOR) method with reduced water contamination, or a gas production process (GPP) which is useful in reducing environmental risks normally associated with transport of crude oil.
    Type: Grant
