  • Determining methane content of a bottom sample
    Patent number: 9243466
    Abstract: A methane content of a bottom sample comprising methane hydrate crystals is determined by:—taking a core sample (5) from a bottom sediment (3) in a deepwater area;—storing the core sample (5) in a storage chamber (4);—lifting the storage chamber (4) to a predetermined waterdepth (BGHZ=Base of Gas Hydrate stability Zone) at which any methane hydrate crystals in the core sample (5) dissociate into water and methane; and—measuring an amount of methane released by the lifted core sample (5).
    Type: Grant
    Filed: November 15, 2010
    Date of Patent: January 26, 2016
    Assignee: Shell Oil Company
    Inventors: Ulfert Cornelis Klomp, Thomas Alexander Pasfield, Kjeld Aaby Sørensen
  • Method for converting hydrates buried in the waterbottom into a marketable hydrocarbon composition
    Patent number: 8678514
    Abstract: A method for producing hydrocarbons wherein hydrates are excavated from the sea bottom and mixed into a transportable slurry, the slurry being pumped to a support vessel, using near sea bottom positive displacement hydraulic pumps, where the hydrates are converted into a hydrocarbon containing stream, with excavation tailings being pumped down to hydraulic motors to drive the hydraulic pumps.
