Abstract: Shunt closures with a compensating piston and methods of using the same. An example shunt closure includes a compensator piston disposed between an oil chamber and a piston chamber and configured to translate towards the piston chamber to allow for an increase in the volume of the oil chamber. The shunt closure also includes a piston coupling connected to the compensator piston; wherein a portion of the piston coupling is configured to translate into the piston chamber upon translation of the compensator piston. The shunt closure further includes the piston chamber configured to house a portion of the piston coupling and the oil chamber configured to house an oil. Thermal expansion of the oil applies pressure to the compensator piston. The shunt closure also includes a shunt isolation sleeve coupled to and adjacent to the piston chamber.

Abstract: A connection assembly for a tube having a first pin attached to the tube, the first pin having a first sealing member; a second pin attached to a jumper tube, the second pin having a second sealing member; and a movable sleeve configured to sealingly engage the first sealing member and the second sealing member.

Abstract: A shroud assembly having two semi-cylindrical covers having a connector at each end; a plurality of receiver rings for supporting the covers and engaging the connector; and an extender ring configured to move a first receiver ring toward a second receiver ring.

Abstract: A shifting tool can include an inner mandrel, engagement members engageable with a well tool component, and a detent device that prevents relative displacement between the inner mandrel and the engagement members, but permits such relative displacement in response to a predetermined longitudinal force. A method of operating a shifting tool can include engaging engagement members with a component of a well tool, and disengaging the engagement members from the component by applying a predetermined longitudinal force, thereby causing the engagement members to retract out of engagement with the component and then extend in the well. Another shifting tool can include a retraction sleeve, engagement members that engage a well tool component, and a detent device that prevents relative displacement between the retraction sleeve and the engagement members, but permits such relative displacement in response to a predetermined longitudinal force.

Abstract: A shifting tool for use in displacing a component of a well tool can include an inner mandrel, at least one shifting key, at least one reset dog, and a retraction sleeve. The shifting key retracts relative to the inner mandrel in response to displacement of the retraction sleeve relative to the shifting key, and the reset dog extends relative to the inner mandrel in response to displacement of the inner mandrel relative to the reset dog. A method of operating a shifting tool can include engaging the shifting tool with a component of a well tool in a well, and applying a force from the shifting tool to the well tool component, thereby causing one or more reset dogs to extend into engagement with the well tool component.

Abstract: A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port.
