  • Patent number: 9835293
    Abstract: Regasification systems and processes for converting liquid natural gas (LNG) from a liquid into a gaseous state are described. The process includes a closed-loop system that uses geothermal wells as a heat source. A warming fluid circulates through the closed-loop system coupled with a geothermal well and a LNG heat exchanger. The warming fluid is heated as it passes through the geothermal well and cooled as it passes through the LNG heat exchanger, thus heating and gasifying the LNG. The cooled warming fluid then returns to the geothermal well. The closed-loop system minimizing environmental impact by eliminating the need to discharge the warming fluid.

  • Publication number: 20130220434
    Abstract: Systems and methods are described that allow for pressure boosting of liquids in a hydrocarbon gas-liquid separator disposed at seabed. The separator can include an upper section and a lower section, which are fluidly coupled via at least one conduit. A first pump can be coupled to the separator that is configured to boost the pressure level of liquid in the lower section while the separator is disposed at seabed.
