  • Method for increased oil recovery from an oil field
    Patent number: 7677309
    Abstract: A method for increasing oil recovery from an oil reservoir in which method surplus gas streams from a plant for synthesis of higher hydrocarbons from natural gas is injected into the reservoir, is described. The surplus streams from the plant is the tailgas from the synthesis and optionally nitrogen from an air separation unit which delivers oxygen or oxygen enriched air to the plant for synthesis of higher hydrocarbons.
    Type: Grant

    Date of Patent: March 16, 2010
    Assignees: Statoil ASA, Petrosa (The Petroleum Oil & Gas Corporation of SA (Pty) Ltd)
    Inventors: Gareth David Huntley Shaw, Ola Olsvik, Erling Rytter, Jostein Sogge, Jan Age Stensen

  • Cooling Water for a Natural Gas Conversion Complex
    Publication number: 20070220905
    Abstract: The invention provides a cooling method for a natural gas conversion complex. The method includes the steps of circulating sea water in a first, open, cooling circuit (12); contacting the sea water with a heat exchanger (14) to absorb heat; cooling the sea water from the outflow of the heat exchanger (14); circulating fresh water in a second, closed, cooling circuit (18); and contacting the fresh water with the heat exchanger (14) to lose heat.

  • Process for the recovery of oil from a natural oil reservoir
    Patent number: 7077202
    Abstract: A method for recovering oil (24) from a natural oil reservoir (18) includes the steps of separating air to produce an oxygen rich stream (40) and a nitrogen rich stream (34), providing a natural gas stream (12) and feeding at least part of the oxygen rich stream (40) and the natural gas stream (12) into a gas to liquid or GTL conversion installation (42) to produce hydrocarbon products (44) and heat. The heat produced in the gas to liquid conversion installation is used to produce energy (20) to pressurize (16) the nitrogen in the nitrogen rich stream (34) to produce a pressurized nitrogen rich stream (22). The pressurized nitrogen rich stream (22) is passed into a natural oil reservoir (18) to enhance the recovery of oil (24) from the reservoir.
