Abstract: An apparatus for controlling the flow of a fluid includes a LP fluid inlet (18) and a LP fluid outlet (9) connected to a flare/vent system. A LP flow line (20) connects the LP fluid inlet (18) to the LP inlet 6a of a jet pump (6). A supply of HP fluid is connected to jet pump inlet (6b), and a MP line (8) is connected to jet pump outlet (6c). A control unit (28) is configured to control operation of first and second LP flow control valves (4, 3) according to signals received from a flow meter (12), so that LP gas is diverted from the flare system to the LP inlet (6a) of the jet pump for pressurisation.

Abstract: Apparatus for and a method of expanding tubulars, and particularly tubulars or a string of tubulars that have one or more per orated portions and one or more non-perforated portions. In one embodiment, the apparatus (150) includes an inflatable element (e.g. a packer 152) that has a shaft (156) rotatably coupled thereto so that the shaft (156) can rotate relative to the inflatable element (152). An expansion cone (158) is threadedly engaged with a threaded portion (156t) of the shaft (156) so that it moves along the threaded portion (156t) upon rotation of the shaft (156) relative to the cone (158).
