A fracturing fluid delivery system is provided. In one embodiment, the system includes a wellhead assembly, a fracturing fluid supply line, a vertical branch extending upward from the fracturing fluid supply line, and a fluid conduit coupling the vertical branch in fluid communication with the wellhead assembly. The fluid conduit may extend linearly from the vertical branch to the wellhead assembly. Additional systems, devices, and methods are also disclosed.

Fracturing fluid delivery system

Fracturing systems with frac valves having gates for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a cavity transverse to a bore. A gate is positioned in the cavity and is movable between open and closed positions to selectively block flow through the bore. The gate includes a seal assembly positioned to seal against a sidewall of the cavity to surround the bore and block flow through the frac valve when the gate is in the closed position. The seal assembly can be actuated between a less-energized state and a more-energized state following movement of the gate within the cavity from the open position to the closed position. Additional systems, devices, and methods for fracturing are also disclosed.

Fracturing valve systems and methods

Fracturing systems having rams for controlling flow through fracturing trees are provided. In one embodiment, a fracturing system includes a frac stack mounted on a wellhead. The frac stack can include a flow control device having a housing and a single ram for opening and closing a bore of the housing. The single ram can form a seal with the housing around the bore without seats. Additional systems, devices, and methods for fracturing are also disclosed.

Fracturing systems and methods with rams

A fracturing fluid delivery system is provided. In one embodiment, the system includes wellhead assemblies, a fracturing manifold trunk line, vertical branches extending upward from the fracturing manifold trunk line, and fluid conduits coupling the vertical branches in fluid communication with the wellhead assemblies. The fluid conduits may extend linearly from the vertical branches to the wellhead assemblies. Additional systems, devices, and methods are also disclosed.

A wellhead system includes a tubing or casing hanger to be installed in a wellhead, the tubing or casing hanger including an outer surface including a landing profile configured to engage a mating landing profile of the wellhead, a landing sensor configured to transmit a signal indicating contact between the landing profile of the tubing or casing hanger and the landing profile of the wellhead, and a processor configured to receive the signal transmitted by the landing sensor.

Systems and methods for assembling a wellhead

A system that includes a wellhead. The wellhead defines a bore. A hanger system is positioned within the wellhead. The hanger system includes a piston angled relative to a longitudinal axis of the bore. A first spring biases the piston in a first direction. The piston contacts a slip segment to couple the slip segment to a casing string.

Hanger system

A connector system configured to couple a first tubular member to a second tubular member includes a body, an outer sleeve positioned circumferentially about the body, and an actuator assembly positioned within an annular space defined between the body and the outer sleeve. The actuator assembly includes one or more piston rods, a primary piston ring coupled to respective first ends of the one or more piston rods, and an actuator ring coupled to respective second ends of the one or more piston rods, wherein the actuator assembly is configured to move axially within the annular space to drive multiple collet segments from an unlocked position in which the multiple collet segments do not engage the first tubular member and a locked position in which the multiple collet segments engage the first tubular member.

Collet connector systems and methods

A fracturing fluid delivery system is provided. In one embodiment, the system includes a fracturing manifold and a fracturing tree. A fluid conduit is coupled between the fracturing manifold and the fracturing tree to enable receipt of fracturing fluid by the fracturing tree from the fracturing manifold through the fluid conduit. Further, the fluid conduit is an adjustable fluid conduit that provides a line-of-sight fluid connection from the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.

Rotating mandrel casing hangers are provided. In one embodiment, a system includes a casing hanger having a lower end configured to engage a casing string and a running tool configured to engage the casing hanger. The system is configured to facilitate rotation of the casing hanger within a casing head to rotate the casing string while cementing the casing string within a well. Additional systems, devices, and methods are also disclosed.
