Abstract: An apparatus and method for placing a member in a wellbore. The apparatus includes member conveyable downhole, a component of the member configured to perform an action in the wellbore, a potential energy source, a locking device and a heat source.

Abstract: Disclosed is a drilling system for rock drilling with a drill string, wherein the drill string includes at least one bendable drill pipe. The drilling system further includes at least two block and tackle systems for driving an end of the drill string in a first direction; and at least two conveyor devices adapted to guide and bend the drill string between the first direction and a second direction, so as to convert a motion of the drill string between the first direction and the second direction.

Abstract: Certain aspects and features of the disclosure relate to a hydraulic connector for use in a wellbore, for example, with or as part of a disconnect tool. The hydraulic connector can isolate hydraulic fluids in upper and lower hydraulic lines using hydraulic pistons. The pistons in the upper and lower parts of the hydraulic connector interconnect mechanically when the connector is engaged and communicate pressure without transferring hydraulic fluid across the interface. The hydraulic fluid can therefore remain confined within the upper and lower hydraulic lines even when the disconnect tool is disengaged, reducing or eliminating incidents of hydraulic fluid leaking or spilling into the wellbore.

Abstract: A frac sleeve assembly and method of operation. The frac sleeve assembly includes a ball seat that retains a frac ball. The ball seat moves within a sleeve. The sleeve includes a profile that separates the first half and the second half to allow passage of the frac ball through the ball seat when the ball seat moves within the sleeve. Alternatively, the ball seat has a ring for receiving the frac ball and the sleeve has a protrusion that selectively engages a shifting pin to move the ring with respect to a ridge to release the ball from the ball seat when the ball seat moves within the sleeve.

Abstract: The pipe wiper assembly of the present invention assists with wiping the pipe as the pipe is removed from the hole (“tripped out”). The pipe passes through the two pipe apertures of the pipe wiper assembly during the removal. Two upper containment arms adjust between an open position and a closed position within the housing to form the upper pipe aperture. The lower containment lip forms the lower piper aperture. The upper containment arms and lower containment lip partially enclose the housing to prevent the wiper from exiting the wiper storage. The containment arms slideably adjust to eliminate the need for hinges. The removal of the hinges provides for easier storage and transportation of the pipe wiper assembly. The removal of hinges also reduces manufacturing costs of the pipe wiper assembly.

Abstract: A downhole tubing string and an umbilical harness are combined in a wellbore. The umbilical harness, which is formed remote from the wellbore, includes an umbilical, and umbilical connectors connected to lines in the umbilical. Connectors attach to well components and make up part of the downhole tubing string. The well components include valves, sensors, and actuators. The umbilical connectors attach to the umbilical at strategic locations so the umbilical connectors can reach and be mated to corresponding component connectors when the umbilical harness and downhole string are combined. Electricity, communication signals, or both, are transmitted along the lines in the umbilical, which are selectively conveyed to each component via the mated connectors. As the umbilical connectors are installed on the umbilical prior to wellsite delivery, the umbilical harness and downhole string are combined by engaging plugs on respective ends of umbilical connectors and corresponding ends of component connectors.
