Publication number: 20220144672Abstract: A floating platform, preferably of the spar type, for treating seawater to provide prepared water for injection into a well extending through the seabed. The platform includes an elongate hull structure vertically position-able in a body of water such that the majority of the hull structure is submerged in the body of water, a deck secured to the top of the hull structure so that the deck lies above a surface of the body of water, and a chamber located within or substantially, within the hull structure so that the chamber is also submerged in the body of water and including a water inlet at a lower end of the chamber and a treated water outlet at an upper end, the chamber containing one or more cells for performing an anti-bacterial treatment on water passing up through the chamber from the inlet to the outlet. The platform further includes a pump for pumping water through the chamber from the inlet to the outlet through the cell or cells. In one configuration, the platform may be a spar platform.Type: ApplicationFiled: March 9, 2020Publication date: May 12, 2022Applicant: Equinor Energy ASInventors: Jostein SOGGE, Cecilie Gotaas JOHNSEN, Arild SAMUELSBERG

Publication number: 20220056790Abstract: A method of producing a fluid from a hydrocarbon well, the fluid comprising an emulsion of water and oil and where the proportion of water (water cut) varies over time. The method comprises: determining whether the water cut of the produced fluid is within the oil/water inversion range; and when the water cut is within the oil/water inversion range, adding water to the produced fluid in order to increase its water cut to above the oil/water inversion range. Thus, the fluid produced transitions from the water-in-oil phase to the oil-in-water phase without (at least significantly) entering the inversion phase.Type: ApplicationFiled: December 18, 2019Publication date: February 24, 2022Inventors: Arild SAMUELSBERG, Cecilie Gotaas JOHNSEN, Jostein SOGGE

Patent number: 7481275Abstract: A method for increasing oil recovery from an oil reservoir by injection of gas into the reservoir, is described. The method comprises separation of air into an oxygen-rich fraction and a nitrogen-rich fraction, reformation of natural gas together with oxygen to produce a synthesis gas for production of methanol or other oxygenated hydrocarbons or higher hydrocarbons. The raw synthesis products and a waste gas from the synthesis are separated, and the nitrogen-rich fraction and at least a part of the waste gas are injected into the oil reservoir to increase the oil recovery from the reservoir. A plant for performing the method is also described.Type: GrantFiled: December 12, 2003Date of Patent: January 27, 2009Assignee: Statoil ASAInventors: Ola Olsvik, Erling Rytter, Jostein Sogge, Jan Age Stensen

Patent number: 7037948Abstract: A method of increasing the production in an existing process plant for converting natural gas into a product, where the natural gas is first converted to a synthesis gas in a synthesis gas section, the synthesis gas is brought to reaction in a reactor for synthesis of the product, where non-converted synthesis gas and product are separated into two streams, where a product-rich stream is taken off the process, while a product-poor stream is re-circulated back as feed to the reactor together with fresh synthesis gas, and where part of the re-circulating stream is taken off the re-circulation loop as a purge gas, where the purge gas is separated into hydrogen-rich and hydrogen-poor streams, where hydrogen-rich streams are introduced in stages of the process where addition of hydrogen is desirable, and where the residual thermal value of the hydrogen-poor stream may be used for heating prior to the stream being discharged, wherein the synthesis gas from the synthesis gas section receives a hydrogen-rich stream fType: GrantFiled: June 27, 2002Date of Patent: May 2, 2006Assignee: Statoil ASAInventors: Roger Hansen, Jostein Sogge, Bjorn Jarle Veland, Ola Olsvik
