Abstract: A composite fracturing tree includes an operating valve and a master valve in fluid communication with the operating valve. The master valve includes an inlet portion in fluid communication with the operating valve, an outlet portion, and a gate portion. The gate portion is disposed between the inlet portion and the outlet portion. The gate portion is moveable between a flow position and an occluding position. In the flow position, the gate portion permits flow between the inlet portion and the outlet portion. In the occluding position, the gate portion prevents flow from the inlet portion to the outlet portion. The gate portion is actuated from the flow position to the occluding position with a closing force and from the occluding position to the flow position with an opening force. The master valve allows for the closing force to reduced compared to conventional fracturing valves.

Abstract: An apparatus for actuating an end-member is disclosed. The apparatus includes a housing, a spring within the housing, and a spring plate forming a restriction for the spring within the housing. A brake member is associated with the spring plate for retaining the spring plate in one or more positions. A drive rod is associated with a motor to enable a first movement of the drive rod and to enable a second movement of spring plate. The first movement or the second movement enables the actuating of the end-member in one or more different positions for the end-member. The brake member may be engaged or disengaged to control or decouple spring compression forces in the actuator when the spring is compressed.

Abstract: In various implementations, a hydraulic fracturing piping system may include one or more rotatable elbows to connect other components of the hydraulic fracturing piping system. Using rotatable elbows may facilitate connections in the hydraulic fracturing piping system. For example, when using a rotatable elbow, in the assembly of the system, the rotatable elbow may be capable of rotating to different positions to facilitate alignment of the hydraulic fracturing manifold and hydraulic fracturing stack (e.g., christmas tree), when the hydraulic fracturing manifold and the hydraulic fracturing stack are not in alignment. In some implementations, the elbow may include an internal radial transition (e.g., of approximately 90 degrees) to control the media being injected into the wellbore. The internal radial transition of the elbow may create a more uniform media flow and/or less turbulence, which may significantly reduce erosion of the inner surfaces the bore of the elbow.

Abstract: A casing rotation system permits rotation of a casing string through a telescoping ring that selectively engages a casing hanger. When the telescoping ring is in a first axial position, it engages the casing hanger such that rotational force is transmitted from a running tool to the casing string. When the telescoping ring moves to a second axial position, it disengages the casing hanger such that rotational force is no longer transmitted to the casing string. The casing rotation system may include an inward-biased locking ring disposed about the casing hanger and optionally a bearing surface that reduces friction on the hangar.
