Abstract: A wellhead housing of a wellhead assembly can include a body having a top end, a bottom end, and a cavity that traverses its length between the top end and the bottom end. The wellhead housing can also include a main channel that traverses the body from the cavity at a distal end of the main channel to an outer perimeter of the body at a proximal end of the main channel, where the proximal end of the main channel is located closer to the top end of the body compared to the distal end of the main channel, and where the distal end of the main channel is located closer to the bottom end of the body compared to the proximal end of the main channel.

Abstract: A tubing spool of a wellhead assembly can include a body having a body cavity, a first channel, and a second channel disposed therein, where the body cavity is configured to receive a tubing hanger used to couple to and suspend a tubing string, where the first channel is configured to be in communication with a tubing string cavity within the tubing string, where the second channel is configured to be in communication with an annulus located between the tubing string and a production casing, and where the first channel and the second channel are each configured to facilitate flow of at least one of a plurality of fluids in either direction independently of each other. The tubing spool can also include a first back pressure valve disposed within the first channel and a second back pressure valve disposed within the second channel.

Abstract: A system for fracturing multiple wellbores on a multi-well pad can include a missile that receives high-pressure fracturing fluid from a plurality of pump truck. The system can also include a main manifold that receives the high-pressure fracturing fluid from the missile, where the main manifold includes multiple valves and multiple output channels, where each of the valves are operated between an open position and a closed position. The system can further include multiple wellbores including a first wellbore, a second wellbore, and a third wellbore, where the wellbores are connected to the output channels of the main manifold. The valves of the main manifold can be operated to enable simultaneous flow of the high-pressure fracturing fluid to the first wellbore, the second wellbore, and the third wellbore so that the first wellbore, the second wellbore, and the third wellbore are fractured simultaneously.

Abstract: An offline casing string rotation system can include a ring gear configured to be coupled to a rotatable mandrel casing hanger, where the rotatable mandrel casing hanger is part of a wellhead assembly and is coupled to a top end of a casing string. The offline casing string rotation system can also include a gear driving assembly moveably coupled to the ring gear, wherein the gear driving assembly, when enabled, causes the gear to rotate the rotatable mandrel casing hanger.

Abstract: A multi-well pad for fracturing a subterranean formation can include a valve assembly that includes a shuttle valve, an inlet, a first outlet, and a second outlet, where the inlet is coupled to a fracturing pump, where the first outlet is coupled to a first well, where the second outlet is coupled to a second well, where first shuttle valve has a first position and a second position. The fracturing pump and the first well can form a continuous first path through the valve assembly while closing off a second path between the fracturing pump and the second well when the shuttle valve is in the first position. The fracturing pump and the second well can form a continuous second path through the valve assembly while closing off the first path between the fracturing pump and the first well when the shuttle valve is in the second position.

Abstract: A testable back pressure valve can include a housing comprising a housing body. The valve can also include a valve seat coupled to the housing, where the valve seat includes a valve seat body having a first cavity and a second cavity, and where the valve seat further includes a first network of channels disposed in the valve seat body. The valve can further include a valve head movably disposed within the first cavity of the valve seat. The valve can also include a piston follower movably disposed within the second cavity of the valve seat, where the valve head is fixedly coupled to the piston follower. The valve can further include a travel piston movably disposed within the second cavity of the valve seat, where the travel piston is moveably coupled to the piston follower.
