    摘要: It is common in oil extraction operations to reinject produced gas and\or water back into hydrocarbon bearing formations in order to maintain formation pressure. Conventional production facilities normally flow all formation fluids to the surface and subsequently reinject the required fluids back into the formation, which can be extremely inefficient due to the high power input required to overcome the large pressure differential between the surface and formation level. A production fluid handling method and apparatus for separating downhole at least gaseous and liquid components (16, 18, 20) of fluid produced from a hydrocarbon bearing formation (12), and reinjecting at least a portion of the gaseous and liquid components (16, 18, 20), as required, back into the formation (12). Re-injection also occurs downhole.

    摘要: A riser control device, particularly designed to be used in connection with spool or horizontal production trees (12) for wells in sub-sea oil and gas installations. Within a housing (1,2) of the device is provided, in opposed direction, radially movable pair of rams (6) for isolating (sealing off) the well and simultaniously, in opposed direction a radially movable pair of shear blades (7) for cutting off an intervention string or the like. The rams (6) and blades (7) are driven by means of a vertically disposed actuator (8,9,23) integrated in the housing (1, 2). The actuator may be in the form of a hydralically driven annular piston (23)/annular chamber (29,30) device, which via piston rods (14) and translation beams (8) transforms the movement of the piston (23) to open or close the rams (6) and shear blades (7).
