A system used downhole in tubing is operable with pressure communicated via at least one control line. The system includes a tool and a stinger. The tool disposed with the tubing has a tool bore for passage of tubing flow. The tool has an operator movable between operable states, and the operator has a tool key disposed in the bore. The stinger removably disposed in the tubing is configured to insert into the tool bore. The stinger has an actuator in communication with the at least one control line. Actuated by the control line, a stinger key disposed on the stinger is movable with the actuator between positions. In this way, the stinger key is configured to engage the tool key and is configured to move the tool's operator at least from the one state to another.

Stinger for actuating surface-controlled subsurface safety valve

A stinger is stabbed into a bore opening of a downhole tool to communicate fluid from a fluid line to the downhole tool. The stinger body defines a bore that communicates with the bore opening of the tool when the stinger body is installed in the downhole tool. An external surface of the stinger body can seal and lock inside an inside surface of the tool's bore opening when the stinger body is installed therein. The stinger body has a flow passage connected to the fluid line. A stinger port in the external surface of the stinger body is in communication with the flow passage and positions in fluid communication with a tool port inside the tool's bore opening so fluid can be communicated to the downhole tool.

A non-damaging slip assembly includes slips having grit on a smooth surface, the slips preferably made from a ductile material, such that the slips do not cause damage to the wall of a tubular when the slips are set. The slips fail under tensile force during setting. The cone used to expand the slips may have slits that narrow during setting of the slips. The slip assembly may be used to anchor a variety or devices inside a tubular. A drillable, non-damaging bridge plug using the non-damaging slip assembly has a threaded mandrel holding the cone by threads inside the cone. When the slips are set, the slits in the cone narrow such that threads in the cone do not allow rotation of the slips as they are drilled. The bridge plug can be drilled by a PDC bit without damaging the tubular.

Multiple ball launch assemblies comprise a plurality of ball launch pods disposed around an outer wall surface of a housing. The ball launch pods are operatively associated with a flow tube disposed within the housing. An actuator assembly rotates the flow tube to align a first opening in the flow tube with a first ball launch pod so that a first ball is launched into the wellbore. Further rotation of the flow tube aligns subsequent openings in the flow tube with subsequent corresponding ball launch pods so that subsequent balls are launched into the wellbore.
