Abstract: The present invention relates to packers adapted to seal an annular space within a wellbore. The packers, for example, may be utilised to circulate or reverse circulate a fluid. In one embodiment, the present apparatus (100) comprises a first tubular subunit (102) and a second tubular subunit (103) moveably coupled together, a flexible packing element (106) disposed between the first tubular subunit and the second tubular subunit, and a temporary mechanical connection adapted to restrain the first tubular subunit and the second tubular subunit from compressing the flexible packing element, in which the temporary mechanical connection is adapted to be hydraulically disengaged. In another embodiment, the present apparatus further comprises a valve (150). In one aspect, the present apparatus further comprises a cement inflation tool. In still another embodiment, the present method comprises locating an apparatus, comprising a packer and a valve positioned above the packer, at a predetermined location within the wellbore; setting the packer, the method of setting the packer comprising, applying a first hydraulic pressure within a central bore of the apparatus and applying down weight on the apparatus; and opening the valve. In one embodiment, the present method comprises actuating a displacement device to displace a fluid below a packer; setting the packer by utilising a predetermined fluid pressure to disengage a temporary mechanical connection between a first surface and a second surface of the packer and by compressing a packing element between the first surface and second surface; and opening a valve above the packer.

Abstract: An apparatus for setting a liner (1) in a casing (2) comprises a liner hanger (LH) and a running tool (100). The running tool (100) is provided with a valve seat (5) obstruction of which, in use, allows fluid pressure to be developed to set the liner hanger (LH) in the well casing (2). After the liner hanger (LH) has been set, the application of further pressure will displace the valve seat (5) to release (or at least enable) the running tool (100) to be released and to allow fluid flow through the running tool (100).

Abstract: A pulling tool for retrieving an object from a wellbore comprises a mandrel (12) fixedly secured to an upper sub (10), an outer cover (220) fixedly secured to and depending from the upper sub, a collet assembly telescopically surrounding the bottom portion of the mandrel and a support sleeve. An expandable fluid cavity (14) is formed between a portion of the facing surfaces of the support sleeve and the mandrel. A coil spring, which is disposed between the support sleeve and the upper sub, downwardly biases the support sleeve so that it rests against a lower shoulder of either the outer cover or the mandrel when fluid pressure is not applied to the expandable cavity. The collet assembly includes a plurality of collet fingers, each having a collet head (210) at the end thereof. The collet fingers are naturally radially biased away from the object to be retrieved. The support sleeve (30) selectively biases the collet fingers and collet heads into engagement with the object to be retrieved upon the removal of fluid pressure in the expandable fluid cavity.

Abstract: A centraliser (1) comprises an upper ring (2) and a lower ring (3) connected by six rigid members (4). The centraliser (1) can be mounted on casing to be lowered down deviated bores. The rigid members (4) are designed to collapse under a lateral load of about 8 tonnes. Thus if, for example, part of the bore collapses and the casing has to be withdrawn the rigid members will collapse enabling the centraliser (1) to be recovered on the casing in one piece.

Abstract: The passive jaws (7, 8) of a power tong (1) are mounted on jaw holders (10) which are slidable in recesses (11) in a rotary (3). The jaw holders (10) have an internally threaded bore (12) which engages a threaded shaft (13) which has a shoulder (14). An actuator (16) is mounted on the housing (2) of the power tong (1) and can advance a drive shaft (17) into a socket in a drive spindle (15) of the threaded shaft (13). Rotation of the threaded shaft (13) in one sense advances the jaws (7, 8) toward the centre of the power tong (1) whilst rotation in the opposite sense withdraws the jaws (7, 8). The drive shaft (17) is withdrawn to enable the rotary (3) to rotate. A jaw holder (10') with a resiliently mounted self-aligning jaw (7') is also disclosed.
