Abstract: 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.

Abstract: 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.

Abstract: Techniques for positioning and setting a barrier within a well string are provided. In one embodiment, a method includes securing a barrier device at a lubricator extension of a lubricator assembly and positioning the lubricator assembly at a wellhead assembly having a wellhead from which a well string is suspended. The method also includes advancing the lubricator extension to advance the barrier device into the well string. The barrier device may be set within the well string to block flow. Additional methods, systems, and devices are also disclosed.

Abstract: A technique facilitates performance of well operations. According to an embodiment, the technique employs a modular assembly configured for coupling with a wellhead assembly. The modular assembly may have a production subassembly and a fracturing subassembly. By way of example, the production subassembly may comprise a connection block positioned for coupling to the wellhead assembly, a production outlet fluidly connected to the connection block, and a valve between the connection block and the production outlet. Additionally, the fracturing subassembly may be releasably coupled to the production subassembly. According to an embodiment, the fracturing subassembly comprises an inlet for receiving fracturing fluids, an outlet coupled to the connection block, and a bore between the inlet and the outlet for communicating a fracturing fluid to a well.

Abstract: A system includes a flow control assembly having a first portion configured to be positioned within and coupled to a first passageway formed in a wellhead component and a second portion configured to be coupled to a second passageway formed in a body that is configured to be coupled to the wellhead component. An actuator of the second portion is configured to drive a valve member of the first portion into an open position to enable fluid flow across the flow control assembly.

Abstract: A system includes a hanger locking assembly configured to lock a hanger within a housing of a wellhead. The hanger locking assembly includes an energizing ring having one or more axially-extending passageways configured to receive and to support one or more control lines. An anti-rotation element extends between the energizing ring and the hanger to block rotational movement of the energizing ring relative to the hanger. A locking ring is in contact with the energizing ring, and axial movement of the energizing ring relative to the hanger drives the locking ring radially to engaged position in which the locking ring extends into a corresponding recess of the housing of the wellhead to block axial movement of the hanger relative to the wellhead.
