Abstract: Provided, in one aspect, is an anchoring subassembly, a well system, and a method. The anchoring subassembly, in one aspect, includes a mandrel, and an isolation element positioned about the mandrel, the isolation element configured to move between a radially retracted state, a fully radially expanded state, and a relaxed radially expanded state. The anchoring subassembly, in one aspect, further includes a ratch latch body coupled to the isolation element, the ratch latch body configured to hold the isolation element in the fully radially expanded state, and a relief feature coupled to the ratch latch body, the relief feature configured to shear to release stored energy in the isolation element and thereby allow the isolation element to move from the fully radially expanded state to the relaxed radially expanded state.

Abstract: A treatment system including a settable and unsettable seal sub, an operation sub connected to the seal sub, the operation sub including a flow restrictor, and a selectively openable port biased to a closed position. A borehole system including a slickline, and a resettable seal connected to the slickline and runnable in the borehole on the slickline. A method for treating a formation adjacent a borehole including running the treatment system on a slickline to a target depth, flowing past the flow restrictor thereby causing the flow restrictor and a mandrel upon which the restrictor is mounted to move toward the seal sub, partially setting the seal sub and increasing pressure on the seal sub thereby fully setting the seal sub. A borehole system, including a borehole in a subsurface formation, a treatment system disposed within the borehole.

Abstract: A high force stroker tool for integration within a wellbore string disposed along a wellbore defined within a subterranean reservoir is provided. The stroker tool includes a hydraulic anchor hydraulically operable to deploy slips securable to the wellbore and to define a mechanical brace, a shifting tool operatively coupled to the hydraulic anchor and comprising a mechanical anchor securable to a movable component, the shifting tool being mechanically operable to move the movable component; and an actuator coupled between the hydraulic anchor and the shifting tool, the actuator being hydraulically operable to brace against the mechanical brace and create a downhole mechanical force adapted to mechanically operate the shifting tool. A method of shifting downhole valve assemblies using the high force stroker tool is also provided.

Abstract: A plug system includes a lower plug, an upper plug, and a sleeve configured to be positioned at least partially within the lower plug, the upper plug, or both. The sleeve defines one or more channels in an outer surface thereof. The sleeve is configured to shift axially from a first position into a second position with respect to the lower plug. In the first position, fluid is prevented from flowing through the one or more channels. In the second position, the fluid is permitted to flow through the lower plug via the one or more channels.

Abstract: A flow control system for a well includes a primary safety valve and a secondary safety valve for controlling flow from production tubing in the well. The primary safety valve includes a first valve body, a first flapper, a first control line port for receiving control fluid pressure from a control line, and a first actuator operable to open the first flapper in response to the control fluid pressure. The secondary safety valve is disposable within the valve body of the primary safety valve. The secondary safety valve also includes a second valve body, a second flapper, a second control line port for receiving control fluid pressure from the same control line as the primary safety valve when the secondary safety valve is disposed in the first valve body of the primary safety valve, and an actuator operable to open the second flapper in response to the control fluid pressure. A choke in fluid communication with the second control line port delays a closing of the second flapper relative to a closing of the first flapper in response to a decrease in the control fluid pressure.

Abstract: An apparatus includes a sub-surface safety valve (SSSV) to be positioned in a wellbore. The SSSV is configurable to move between a closed position and an open position. While in the closed position, the SSSV prevents downhole fluid in the wellbore to flow to a surface of the wellbore. While in the open position, the SSSV allows the downhole fluid in the wellbore to flow to the surface of the wellbore. The apparatus further includes an electrostatic motor to be positioned in the wellbore and to be coupled to the SSSV. The electrostatic motor is to be selectively powered to move the SSSV between the closed position and the open position.

Abstract: A trigger system for use with a downhole tool. The trigger system may include a first housing forming a first pressure chamber at a first pressure and including a membrane positioned in a wall of the first housing, a piston disposed at least partially within the first housing and shiftable from an initial position to an actuated position to actuate the downhole tool, and a trigger. The trigger may include a second housing sealed against the first housing proximate the membrane to form a second pressure chamber at a second pressure and a rupturing member positioned within the second housing and operable to pierce the membrane to balance the pressures within the first housing and the second housing and shift the piston from the initial position to the actuated position.

Abstract: A pressure control system configured to respond to high-pressure conditions in a fluid conduit is disclosed. The system generally includes first and second flow restrictors positionable inline on a fluid conduit and configured to block fluid flow in the conduit and respond to a high-pressure event to allow fluid flow therethrough. The first flow restrictor is position upstream from the second flow restrictor and may open to allow fluid flow in response to the high-pressure event. The second flow restrictor provides adjustable flow of fluid therethrough or may open a bypass line in response to the highpressure event to allow unrestricted fluid flow therethrough.
