摘要： A remote hydraulic system for controlling a valve of a wellhead or frac manifold includes a remote hydraulic skid, control skid, and power supply skid. The remote hydraulic skid includes a hydraulic reservoir, a hydraulic pump, an accumulator, a hydraulic manifold operatively coupled to the accumulator, and a hydraulic valve operatively coupled to the hydraulic manifold. The hydraulic valve is operatively coupled to the valve of the wellhead or frac manifold by a hydraulic line. The control skid includes an interface and is operatively coupled to the remote hydraulic skid. The power supply skid is coupled to the remote hydraulic skid to provide the power necessary to drive the hydraulic pump on the remote hydraulic skid. The remote hydraulic skid is positioned within a hazardous zone around the wellhead, while the control skid and power supply skid are positioned outside of the hazardous zone.

摘要： A ball dropper assembly includes a main body, a sealing piston, and a magazine assembly. The main body includes a main bore, angle bore, and transverse bore formed therethrough. The transverse bore is fluidly coupled to the main bore through the angle bore. The sealing piston is positioned within the transverse bore. Seal rings are positioned between the main body and the sealing piston on either side of the angle bore. The magazine assembly includes a magazine body and a carrier piston. The magazine body is mechanically coupled to the main body. The carrier piston has a carrier hole formed therein and is mechanically coupled to the sealing piston.

摘要： A fluid transfer system for use with a valve tree at a well, the valve tree having a wellhead axis, may comprise a header having a header flow axis and a coupler connected to the valve tree and the header and providing fluid communication between the valve tree and the header, the coupler having a coupler flow axis. The sum of the direction changes for a fluid flowing from the header into the valve tree may be less than 225°. The coupler may include a coupler inlet, which may be at substantially the same elevation as the header flow axis. The coupler may be connected to the header such that the coupler flow axis intersects the header flow axis or such that the coupler axis passes between the header axis and the surface of the earth. An angle between the coupler flow axis and the wellhead axis may be acute.

摘要： A valve position indicator for a valve includes an outer housing, actuation rod, indicator flag, and follower. The actuation rod is positioned within the outer housing, which is couplable to a tail stem protector of the valve. The actuation rod may have a helical slot formed therein. The actuation rod may be rotatably coupled to the outer housing. The indicator flag may be coupled to the actuator rod and may extend radially therefrom. The follower may be couplable to a tail stem of the valve. The follower may extend in a direction perpendicular to the extent of the tail stem. The follower may extend through a slot in the tail stem protector and into the helical slot of the actuation rod when the valve position indicator is coupled to the tail stem protector.

摘要： An isolation sleeve for a wellbore includes a sleeve body and a torque sleeve. The torque sleeve threadedly couples to the sleeve body. The torque sleeve includes a compression shoulder. The isolation sleeve includes a compression seal positioned about the torque sleeve between the compression shoulder and the sleeve body. The isolation sleeve also includes a lock ring coupled to the sleeve body that engages a packoff. The lock ring is urged into engagement with the packoff by an energizing ring.
