摘要： A liner hanger system enables installation of a liner hanger by means of a full bore casing to surface and provides pressure integrity between the casing's inner and outer sides. The liner hanger system comprises a liner hanger, along with an associated liner, coupled to a tieback casing string. The liner hanger and liner are deployed downhole connected to a tieback casing string. Once the liner has been lowered to the position of interest, first the liner hanger is anchored and cemented in position, and then, a packer is set to seal the lower annulus of the liner. The liner hanger system enables operations that used to require a plurality of trips, to be performed in a single trip. It does so without introducing any unwanted limitation to the inner diameter at any point between the wellhead and the end of the liner, and while also allowing for potential decoupling and removal of the tieback casing string from the liner hanger if desired.

摘要： A work string assembly for an oil or gas well has a first and second tubulars, and a torque limiting device connected in the work string. The torque limiting device has a body with an axial bore and two interconnected members that can disconnect to be relatively rotatable. The interconnected members can be repeatedly re-engageable when the torque levels drop below a torque threshold value, or can be connected by a frangible member that is broken when the interconnected members disconnect. A selectively actuable circulation port provided in the string adjacent to and above the torque limiting device allows the annulus between the work string and the casing to be flushed with fluid from the port.

摘要： A swivel configured to rotationally decouple an upper section of a work string from a lower section of the work string. The swivel includes an upper body coupled to a lower body by a ring member and a plurality of shearable members. The lower body has a plurality of teeth members that engage a plurality of teeth members of the ring member. Rotation of the upper body is transmitted to the lower body by the ring member. The upper body is rotatable relative to the lower body when the shearable members are sheared.

摘要： A back-off shot tool system includes a high-pressure resistant charge housing at least partially containing an explosive material. A booster charge is placed adjacent the explosive material to activate the explosive material upon actuation. The high-pressure resistant charge housing is formed from a material that is the material of the high-pressure resistant charge housing is frangible so that it will to withstand high temperatures and pressures, such as a ceramic. In addition, fragment into small pieces that can be process or extracted from the well with fluid that is extracted from the region in which the back-off shot tool is deployed.

摘要： Systems and methods for the down-hole automatic mechanical coupling and alignment of a first sensor module and a second sensor module are provided. A mating element of a first sensor module includes a sheath with a first cam and a shroud surrounding the first cam. A second mating element of a second sensor module includes a second cam complementary to the first cam. Upon mating, the sheath surrounds at least a portion of the second mating element and the first cam seats against the second cam, with a predetermined axial orientation with respect to each other.

摘要： Methods and systems relate to seabed operations, such as well intervention or capping, involving subsea equipment and subsea handling of the equipment, which may be associated with hydrocarbon wells or pipelines. A subsea system submerges during deployment and is landed on the seabed. The system may include a suspension assembly coupled to a frame structure for carrying equipment used in the operations. The deployment of the system may include deploying the frame structure with the equipment from a floating vessel connected to an anchored tether and moving the frame structure under water along the tether toward where anchored and the location for the seabed operations.

摘要： Force-dampening arrangement (100) for dampening forces between two interconnectable parts in a tube string, of which interconnectable parts a lower part (101) is connected to the upper end of a string element (105, 3a) extending into a subsea well (5) and an upper part (103) is suspended from a floating surface installation (1) through at least one suspension element (3b) extending up to said surface installation. The force-dampening arrangement (100) is connected to the tube string above a string-portion (3a) extending into said subsea well, and below at least a portion of said suspension element (3b). The force dampening arrangement (100) exhibits an upper and lower section (109, 111) that are vertically movable in relation to each other, thereby yielding for impact forces between said interconnectable upper and lower parts (103, 101) resulting from vertical heave movement of said portion of suspension elements (3b) moving vertically in respect of the string element (3a).
