  • Enhanced coal-bed methane production
    Patent number: 9810050
    Abstract: Methods and systems for enhanced recovery of coal bed methane. A method includes generating a diluent gas mixture comprising N2 and CO2 in a semi-closed Brayton cycle power plant, injecting at least a portion of the diluent gas mixture into a coal bed, and recovering a mixed production gas comprising methane from the coal bed.
    Type: Grant

    Date of Patent: November 7, 2017
    Assignee: ExxonMobil Upstream Research Company
    Inventors: O. Angus Sites, Lalit K. Bohra
  • Processing exhaust for use in enhanced oil recovery
    Patent number: 9784140
    Abstract: A method for generating steam for hydrocarbon production is provided. The method includes producing steam using heat from an exhaust stream from a gas turbine system. A water stream is condensed from combustion products in the exhaust stream, and the water stream is used as a make-up water for production of the steam.

  • Regasification Plant
    Publication number: 20140245779
    Abstract: Methods and system are provided for regasifying liquefied natural gas (LNG). An exemplary method disclosed includes flowing at least a portion of an LNG stream through an air separation unit (ASU) to form at least a portion of a natural gas (NG) stream. Heat is removed from an airflow in the ASU to separate an oxygen stream from the airflow. The oxygen stream and a fuel stream are combusted in a power plant.
