Abstract: A wellbore system comprising a housing assembly and a hanger assembly. The hanger assembly comprises an actuation member that interacts with a portion of the housing assembly when the hanger assembly is positioned at a desired location in the housing assembly. The hanger assembly also comprises a load member that is adapted to extend between the hanger assembly and the housing assembly to enable the housing assembly to support the hanger assembly. The load member is carried into the wellbore in a retracted position. When the actuation member interacts with the housing assembly at the desired location, the actuation member actuates the load member to expand outward to extend between the hanger assembly and the housing assembly. The actuation member is adapted to transfer a lifting force from the surface to the load member to enable an over-pull test of the hanger assembly to be performed.

Abstract: An apparatus for use in cleaning a drill string comprises a body portion (10) having a tubular side wall and a resiliently compressible cleaning member (11) mounted inside the hollow interior thereof under compression, the body portion (10) comprising an open lower end adapted to engage the drill string. A separate actuator (13) is provided for fitting to the body portion (10) for displacing the cleaning member (11) out of the tubular side wall of the body portion (10) into the drill string. In use, the cleaning member (11) can be loaded into the body portion (10) at a remote location prior to the cleaning operation thereby reducing the time taken to insert the cleaning member (11) into the drill string and alleviating the risk of injury.

Abstract: A method of flushing a wellbore fluid from a downhole tool containing a bearing package includes pumping hydraulic oil through at least one of a hydraulic inlet line and at least one of a pneumatic inlet line connected to the main housing and into an annulus formed between the bearing package and a main housing of the downhole tool, wherein the hydraulic oil replaces the wellbore fluid in the annulus, removing the wellbore fluid from the annulus through at least one hydraulic outlet line and at least one pneumatic outlet line connected to the main housing, pumping air through the at least one pneumatic inlet line connected to the main housing and removing the hydraulic oil from the at least one pneumatic inlet line connected to the main housing, and removing the hydraulic oil through at least one pneumatic outlet line connected to the main housing.

Abstract: A disconnect device comprises a tubular member having a window for receiving an engagement member, and a sleeve having connected and disconnected positions. The engagement member engages with a component of a downhole string to connect the disconnect device to the rest of the string such as through a helically-shaped thread disposed on the engagement member and on the component. The window can comprise at least one wall that is outwardly tapered so as to prevent the engagement member from passing through the window when the tubular member is disconnected from the component of the string. The engagement member is maintained within the window by the sleeve when in its connected position to maintain the connection between the tubular member and the component. When moved to its disconnected position, the engagement member disengages the component by moving inwardly into the bore of the tubular member.

Abstract: A safety apparatus for catching a test fixture released from a shaft of a downhole tool during the uphole calibration and testing of the shaft force generation capability of the tool. The safety apparatus includes a hollow body having a distal end that will partially envelope the test fixture to catch the test fixture once the test fixture is released from the downhole tool. The safety apparatus further includes a proximal end portion that is releasably securable to the body of the tool. A method for testing and calibrating the tool is also provided.

Abstract: A leak detection method uses a comparator to compare fluid values in and from the latch assembly of the latch system for an oilfield device and/or in and from the bearing assembly of a rotating control head.

Abstract: A method of completing a well having a casing hanger set in a subsea wellhead housing includes attaching a running tool to a tubular bridging hanger. A metal-to-metal inner seal is attached to a lower exterior portion of the bridging hanger and a metal-to-metal outer seal is located on an upper exterior portion of the bridging hanger. The assembly is lowered into the well and the lower exterior portion of the bridging hanger is inserted into the casing hanger. The inner seal is wedged between the casing hanger and the bridging hanger in response to weight of the running string. The running tool is actuated to set the outer seal between the upper exterior portion of the bridging hanger and the wellhead housing. Then, a tubing hanger is landed and sealed in the interior of the bridging hanger.

Abstract: A wellhead seal assembly forms a metal-to-metal seal between inner and outer wellhead members. A metal seal ring has inner and outer walls separated by a slot. An energizing ring has a C-ring captured on its outer surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages a profile on the seal ring, locking the energizing ring to the seal assembly.

Abstract: A wellhead seal unit for sealing a subsea oil and/or gas well at the wellhead. The unit comprises a sleeve, sealingly engaged to the workstring and to which, blow out preventer rams can engage. The unit allows the workstring to be rotated and reciprocated within the wellbore without releasing the seal. Methods of cleaning the sealed well and performing an inflow test are described.

Abstract: Disclosed herein is a method of sealing a tieback to a tubular. The method includes, positioning a metal deformable member of the tieback within a tubular and contacting the tubular with a sleeve of the tieback. Moving the sleeve in a first axial direction thereby contacting and radially deforming a first portion of the deformable member by axially compressing the deformable member and sealably engaging the tubular with the radially deformed first portion.

Abstract: A wellhead assembly including a wellhead housing. The wellhead housing comprises a throughbore having a recessed sealing area and a tubing hanger positioned in the throughbore. A seal is positioned between the wellhead housing and the tubing hanger, the seal being positioned so as to form a gap between the seal and the wellhead housing. The wellhead assembly can further include a seal energizer capable of moving relative to the seal in a manner that forces the seal against the wellhead housing to bridge the gap. A method of installing a tubing hanger into a throughbore of a wellhead housing is also disclosed.

Abstract: A deformable member can be used in a well tool for use in downhole oil/gas wells. In one embodiment, a deformable member is described which is deformable between undeformed and deformed positions, and comprises a generally hollow cylindrical body defining a wall. The wall includes three circumferential lines of weakness in the form of grooves, with two grooves provided in an outer surface of the member wall and the other groove provided in an inner surface. The member is deformed outwardly by folding about the lines of weakness and is used in particular to obtain sealing contact with a tube in which the member is located.
