    摘要: A seal assembly disposed within a radial seal groove to sealingly engage a bonnet within a bore. The seal assembly includes a radial seal surface, an axial seal surface, a vent surface, and an axial preload surface. The seal assembly is thrust towards a longitudinal wall and away from a radial wall of the radial seal groove when pressure in a high-pressure zone increases.

    摘要: A device and method for cutting a downhole object, such as a slickline, wireline or tubular is described. The device comprises first (20) and second (22) cutting members each rotatably mounted within a main housing (14) and adapted for contra-rotation. In an embodiment of the invention, the device is provided with a guide assembly (24) for locating the object in a central location of the device, and cuts the object at a single location along the length of the object with a scissor action.

    摘要: The consequences of any failure of a blow out preventer assembly to operate correctly in an emergency can be far reaching. Thus, there is provided an apparatus for registering parameters in the bore of a member which is, in use, connected to a pressurised housing, the apparatus comprising: an electro-control package for attachment, in use, to the member; a test assembly placed, in use, in the member; the electro-control package and the test assembly having means for sending signals to and receiving signals from one another.
