Abstract: The present invention provides a connector arrangement for connecting a first tubular to a second tubular. In particular, the present invention relates to a method for connecting tubulars in such a way that the connection is prevented from becoming unmade in response to expansion of the tubulars in a wellbore. More particularly, the present invention provides a tubular connection using a helical or spiral thread insert to seal and maintain mechanical strength in a tubular connection after expansion.

Abstract: A plunger-type valve is arranged to selectively allow fluid flow to enter and exit the valve in both directions (differential fill valve, dependent on differential pressure). Subsequently, the plunger-type valve can be deactivated to selectively allow fluid flow in only one direction (check valve, float shoe). The valve includes a body (105, 120), at least one locking segment (110), a locking sleeve (170), at least one biasing member (115), a valve seat (160), a valve seat (160) and a plunger (150).

Abstract: A method of anchoring tubing in a bore comprises: providing first tubing having a section with a wall configured to provide outer surface portions describing a diameter less than a first diameter. The tubing is located within a bore comprising a first section having an internal diameter greater than the first diameter and a second section having an internal diameter corresponding to the first diameter, with the tubing section in the first section of the bore. The tubing section is then reconfigured such that the outer surface portions describe a tubing diameter greater than the first diameter. The tubing is then axially translated relative to the bore to locate the tubing section in the second section of the bore such that the outer surface portions are restrained to the first diameter by the bore, and the outer surface portions engage with the bore.

Abstract: The present invention provides methods for expanding coiled tubing within a wellbore in order to form a patch. In one aspect, an expansion assembly is run into the wellbore at the lower end of a string of coiled tubing. The expansion assembly includes a cutting tool and an expander tool. The coiled tubing is run into the wellbore such that the expander tool is adjacent a portion of surrounding casing or other tubular body to be patched. The expander tool is actuated so as to expand a selected portion of the coiled tubing into frictional engagement with the surrounding casing, thereby forming a patch within the wellbore. The cutting tool is actuated so as to sever the coiled tubing downhole above the patch. The severed coiled tubing is then pulled, thereby removing the expansion assembly from the wellbore as well.

Abstract: A method and apparatus for setting a liner (200) in a wellbore and then expanding a screen (213) in the wellbore in a single trip are disclosed. A liner and expandable screen is provided with a slip assembly (210) to fix the liner in the wellbore. An expansion tool (105) and work sting is run into the wellbore in the liner. After the liner is set, the expansion tool is used to expand the screen. In an embodiment, an annular area (360) between the expansion tool and work string is utilized in order to set the slips (238). Thereafter, cup packers used in forming the annulus are lifted from the liner prior to expanding the screen.

Abstract: A method of lining a drilled bore comprises running an expandable first tubular into a bore and locating part portion of the first tubular in an unlined section of the bore and another portion of the first tubular overlapping a portion of an existing second tubular. The first tubular is secured relative to the second tubular while retaining the provision of fluid outlets to permit displacement of fluid from an annulus between the first tubular and the bore wall. An expansion device is then run through the first tubular to expand the first tubular to a larger diameter. Cement is then circulated into the annulus between the expanded first tubular and the bore wall. The fluid outlets are then closed.

Abstract: A jar mechanism comprises a housing (22) having a fluid chamber (9) therein, a piston (5) encircled by an annular metering sleeve (19) and movably mounted in the fluid chamber for movement between a first position and a second position, and a jar member (2) moveably mounted in the housing such that a pull or push force exerted on the jar member moves the piston from the first position to the second position within the fluid chamber against the resistance of the fluid, and the action of the pull or push force exerted on the jar member actuates a release device. The jar member is releasably coupled to the piston by the release device (3,4) such that, when the piston is in the first position in the fluid chamber, the jar member is coupled to the piston by the release device for movement therewith. Actuation of the release device enables the jar member to be uncoupled from the piston.

Abstract: Apparatus for attaching a downhole isolation, production, or testing tool is disclosed such that the tool is mechanically attached to a mandrel in a manner that is highly resistant to axial movement. The mechanical connection resists high temperatures, high pressures, and corrosive fluids and gases that may be encountered in the well without the use of welding to a casing mandrel. In general, the connection includes at least one groove or channel (48) cut in an outer wall of the casing mandrel, and at least one partially or fully annular slot (62) on the inside surface of the tool oriented to correspond with the groove(s) in the outer wall of the casing mandrel. At least one lock (64) is situated in the corresponding slot (62) and the groove (48). The lock (64) engages the flanks of the slot (62) and groove (48) sufficiently to resist shears loads applied by compression or tension in the string, and thereby restrains axial movement of the valve assembly relative to the casing mandrel. In one embodiment, the lock is one or more wires (64), although other mechanical locking devices may be installed to provide the same function.
