Abstract: A method, system and apparatus for producing hydrocarbons from a low permeability reservoir formation. A wellbore (3) with a plurality of fractures (7, 9) designated as one of a first (7) or a second (9) set of fractures is provided. A first fluid conduit (11) is formed by an annulus between an outer casing (10) of a tubular and an inner tubular (16) member, and is arranged to transport produced hydrocarbons. An interior of the inner tubular member forms a second fluid conduit (12) which is arranged to transport an injection fluid. A set of first openings (14) is provided in fluid connection with the first fluid conduit, each first opening being located to substantially align with one of a first set of fractures. A set of second openings (15) is provided in fluid connection with the second fluid conduit, each second opening being located to substantially align with one of a second set of fractures. A high pressure fluid is injected into the second set of fractures, which pushes hydrocarbons located in the low permeability reservoir towards the first set of fractures, thereby increasing the recovery rate of hydrocarbons in the low permeability reservoir.

Abstract: A method of plugging a well extending into a hydrocarbon bearing formation facilitates temporary or permanent abandonment of the well. The method includes forming two or more plugs within the well, the plugs being formed at longitudinally spaced apart locations whilst providing a fluid communication path from a region above the topmost plug to the or each space between adjacent plugs. This configuration facilitates pressure testing of one or more of the plugs by conducting fluid through said path.

Abstract: A subsea oil and/or gas production system comprises a host production facility and a plurality of subsea wells. A fluid conveying network is provided that connects each subsea well to the host production facility. A separate electrical power and data network is provided for conveying direct current electrical power and data, operatively connected to each subsea well for providing each subsea well with data transfer and electrical power services. The use of direct current ensures that the electrical power and data network can provide power over much greater distances than currently available, and the use of separate networks for conveying fluids and for providing electrical power and data transfer allows for a much more flexible system.

Abstract: A method of processing a fluid produced from a well, the produced fluid being a high pressure fluid, the method comprising: reducing the pressure of the fluid to a reduced pressure such that a gas phase and a liquid phase are formed; separating the gas phase from the liquid phase thus forming a gas product and a liquid product; and storing the liquid product in a storage tank at a pressure such that the liquid product remains in a stable liquid phase during storage, wherein the reduced pressure is greater than atmospheric pressure.
