A system including a positive lock system, including a lock ring system, including a load ring configured to engage a tubular, and a lock ring configured to radially energize the load ring by moving only in an axial direction.

An adjustable mudline suspension system, including a tubing hanger having an exterior profile, a clamp having an inner profile to mate with the exterior profile of the tubing hanger, a biasing element to bias the clamp radially inward into an engaged position where the inner and exterior profiles are mated, and a piston to bias the clamp radially outward into a disengaged position where the inner and exterior profiles are not mated when hydraulically actuated. The weight of the tubing hanger is supported by the adjustable mudline suspension system when the interior profile of the clamp mates with the exterior profile of the hanger.

Systems and methods are provided that may include employing a lockscrew to provide radial and axial force in connecting tubular members in a mineral extraction system. The lockscrew may be angled relative to the tubular members, at an angle that is greater than 0 degrees and less than 90 degrees. Further, the lockscrew may have an end portion which mates with a slot in a locking segment, and the lockscrew and locking segment may be moved from an unlocked to a locked position. In a locked position, the lockscrew exerts force axially downward and radially inward to push the locking segment against a tubular member, locking the member in place. The interconnection between the lockscrew and the locking segment may enable easier installation and may utilize parts which may be easier to manufacture. Furthermore, the angle of the lockscrew may provide improved support for tubular members.

A wellbore completion system includes an expandable liner hanger with a post-setting fluid flow path. The system includes an expandable liner hanger that can be expanded by a running tool prior to a completion operation in a wellbore. The system also includes a circulating sleeve that can be manipulated by the running tool. The circulating sleeve can provide a return path for fluid internal to the expandable liner hanger for the completion operation that is performed subsequent to releasing the running tool from the expandable liner hanger.

Technologies are generally described for apparatus, systems, and methods to reduce cost and simplify couplings for wellhead equipment and related cable assemblies. The wellhead equipment is placed on a well that is bored into the ground. The wellhead cable may employ a splice assembly that includes a downhole cable, a surface cable, and a conduit. The surface cable is spliced with the downhole cable below a wellhead hanger. The conduit may be configured to contain the surface cable and terminate in the explosion-proof conduit box located at the surface. An inner space of the conduit may be sealed below the wellhead hanger. The conduit may be break-free, or contiguous, between the wellhead hanger and the explosion-proof box.

A wellbore system includes a slip hanger arranged within a wellbore component, the slip hanger having a mechanical receptacle formed in a face of the slip hanger. The wellbore system also includes an adapter configured to couple to the slip hanger, the adapter having one or more engagement members arranged to engage the mechanical receptacle, wherein the one or more engagement members extend into the mechanical receptacle to secure the slip hanger to the adapter.

A system includes a tubing head spool (THS) installed in a non-plugged wellbore, the THS having a bore diameter to permit passage of one or more wellbore components corresponding to one or more wellbore components that pass through an associated blowout preventer (BOP). The system also includes an orientation sleeve arranged within the THS and installed, the orientation sleeve being positioned and aligned within the THS via one or more engagement features mating with one or more orientation features within the bore.

An apparatus and method for placing a member in a wellbore. The apparatus includes member conveyable downhole, a component of the member configured to perform an action in the wellbore, a potential energy source, a locking device and a heat source. The potential energy source is capable of activating the component. The locking device constrains the potential energy source from activating the component when the locking device is in a first state. The heat source changes the locking device from the first state to a second state in which the locking device allows the potential energy source to activate the component.

A method for snubbing a wellhead hanger into a wellhead is provided. In one embodiment, a snubbing method includes snubbing a tubing hanger into a wellhead housing from a snubbing unit. Snubbing the tubing hanger into the wellhead housing can include lowering the tubing hanger into a bore of the wellhead housing under pressure and allowing fluid in the bore to pass along an exterior of the tubing hanger to balance fluid pressure above and below the tubing hanger as the tubing hanger is lowered. The tubing hanger can be positioned at a location in the bore of the wellhead housing, which can be elastically deformed to grip and secure the tubing hanger at the location in the bore. Additional methods, systems, and devices are also disclosed.

A wellhead assembly with a gripping device for securing multiple components of the wellhead assembly is provided. In one embodiment, a system includes a wellhead housing mounted above a hollow body, such that an axial bore extends through the wellhead housing and the hollow body, and a wellhead hanger positioned within the axial bore. The system also includes a clamp that provides a first grip that secures the wellhead housing to the hollow body and a second grip that secures the wellhead hanger within the axial bore. The second grip includes elastic deformation, via the clamp, of at least one of the wellhead housing or the hollow body into tight engagement with an exterior of the wellhead hanger to secure the wellhead hanger at the location within the axial bore. Additional systems, devices, and methods are also disclosed.
