Fracturing systems with frac valves for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a bore to convey fracturing fluid, a seal disposed within the bore, and an actuator coupled to control movement of the seal. The actuator can be disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore. Additional systems, devices, and methods for fracturing are also disclosed.

Inline fracturing valve systems and methods

A wellhead hanger assembly is provided. In one embodiment, a system includes a wellhead hanger, an inner sleeve coupled to the wellhead hanger, a running tool coupled to the inner sleeve, and an outer sleeve coupled to the running tool. The outer sleeve may be positioned to transmit torque from the running tool to the wellhead hanger, and the wellhead hanger may be in castellated engagement with the outer sleeve via a set of castellations and mating slots. Additional systems, devices, and methods are also disclosed.

Rotating hanger assemblies and methods

A technique enables maintenance of sufficient clearance between a wellhead and, for example, a mobile rig. The technique facilitates support of a cable, e.g. an antenna suspension cable, at the wellhead without detrimentally affecting the desired clearance. According to an embodiment, a flange system is used in combination with a cable clamp assembly at a wellhead. The flange system may comprise a flange having a connector portion configured for coupling with the wellhead. The flange also comprises a cylinder portion coupled to the connector portion such that the cylinder portion extends into a corresponding bore of the wellhead. The cable clamp assembly is configured to clamp around and support a cable extending down through the wellhead. The cable clamp assembly is supported within the cylinder portion of the flange such that the cable clamp assembly is at least partially disposed within the wellhead.

Flange system

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.
