摘要： An improved anti-rotation device and connector assembly designed to prevent rotation of a first threaded portion of the connector assembly with respect to a second threaded portion of the connector assembly is provided. The anti-rotation device and connector assembly include features that guide and smooth the transition of the anti-rotation device into a position extending through the first and second threaded portions. The anti-rotation device may extend through a tab/groove interface between the first and second threaded portions, or the anti-rotation device may engage opposing interfacing edges of the first and second threaded portions along the length of the anti-rotation device. Once the anti-rotation device is installed through the first and second threaded portions, the anti-rotation device may prevent rotation of the threaded portions relative to each other.

摘要： An improved anti-rotation device for preventing rotation of two joined tubular members of a connector assembly is provided. The connector assembly includes a first threaded portion connected to a second threaded portion. The anti-rotation device includes at least one self-tapping screw installed in an associated threaded bore formed in and tangential to a flange of the second threaded portion. When installed, the at least one self-tapping screw engages a shoulder of the first threaded portion. A partial thread is formed in the shoulder of the first threaded portion by the at least one self-tapping screw, which forms a shear-resistive force that prevents rotation of the first threaded portion relative to the second threaded portion, and thus prevents rotation of one tubular member relative to the other.

摘要： An improved c-ring slip retention system and method for extraction of the c-ring slip are provided. The c-ring slip retention system may use an axially movable support sleeve with a support ring for securing the c-ring slip against a retention lip of the liner hanger body. The disclosed retention system prevents the c-ring slip from being prematurely extracted from a liner hanger body while the liner hanger is lowered through a borehole. The c-ring slip retention system may also include anti-rotation features that prevent the c-ring slip from rotating relative to the liner hanger body. A single actuation of the support sleeve in an axial direction may unlock the c-ring slip from the retention lip, disengage the anti-rotation features, compress the c-ring slip out of the keyed profile, and extract the c-ring slip from the liner hanger body.

摘要： A hybrid-tieback seal assembly and methods for tying a well back to the surface or subsea well head are disclosed. A method to tie a well back to the surface or subsea well head comprises running a hybrid-tieback seal assembly into a wellbore, the hybrid-tieback seal assembly comprising one or more anchoring bodies, one or more packer seal assemblies; and a device for creating a pressure differential in a tieback string, wherein the tieback string is coupled to the hybrid-tieback seal assembly. The method further comprises landing a casing hanger in a well head, increasing pressure in the tieback string, setting the anchoring bodies and one or more packer seal assemblies within at least one of a previously installed liner hanger system and a host casing above a previously installed hanger system, and testing the hybrid-tieback seal assembly down an annulus between the host casing and the tieback string.
