A slickline stuffing box shock absorber is disclosed. The slickline stuffing box shock absorber includes a first mechanical component adapted to connect to a slickline in a wellbore, an upper rod rigidly coupled to the first mechanical component, a second mechanical component adapted to connect to a rope socket of a tool string in the wellbore, a lower rod rigidly coupled to the second mechanical component, and a spring adapted to absorb shock energy from the tool string so as to prevent breakage of the slickline, where the upper rod is hollow and has a larger inner diameter than an outer diameter of the lower rod to allow sliding movement of the lower rod inside the upper rod, and where the upper rod and the lower rod are elastically coupled to each other by the spring.

Methods, system and devices for deploying an MI cable heater down-hole into a hydrocarbon reservoir are provided, wherein one or more MI cables are housed inside a protective jacket, and connected to a pump-in device. The pump-in device allows the cable to be deployed by pumping fluid down-hole, and the pump-in device catches the fluid and pulls the cable down-hole, even in a horizontal well.

A technique facilitates rigless deployment of a pumping system, e.g. an electric submersible pumping system, to a desired downhole location. The pumping system is coupled to an electrical cable which is routed FIG. 2 through an injector head. The pumping system is supported on the electrical cable and conveyed downhole to the desired position in a wellbore via the injection head. The system and methodology enable deployment of the electrical cable directly through the injector head without coiled tubing.

The described pack-off assembly includes a tubular sleeve that is configured to selectively encompass a pack-off wireline seal and that is positionable through selective application of pressurized fluid to one or more actuation chambers that interact with a piston portion of the sleeve. Pressure may be applied to position the sleeve to encompass the seal to engage a wireline and enable pressure-control wireline operations. A different pressure may be applied to position the sleeve to expose the seal for servicing.

A cable hanger for use in a tree of a well including a bore includes a body and first and second barrier systems located on the body. The first barrier system includes a first seal configured to seal against the bore of the tree to establish a pressure barrier, and a first latching mechanism, wherein upon actuation, is configured to engage the tree and hold the cable hanger in place in the tree. The second barrier system includes a second seal configured to seal against the bore of the tree, and a second latching mechanism, configured such that upon actuation, it engages the tree and holds the cable hanger in place in the tree. The cable hanger further includes at least one of a hydraulic line or an electrical conductor extending through a portion of the body.

Dual path control fittings have a fitting body and a cylindrical plunger. The fitting body has a cylindrical bore, a first conduit, and a second conduit. The cylindrical bore provides a first inlet and an opening. The first conduit provides a second inlet. The second conduit provides an outlet. The cylindrical plunger is mounted for reciprocation in the bore and has a first conduit and a second conduit. The first conduit extends from one end of the plunger to a port on the circumference of the plunger. The second conduit extends transversely across the plunger. The plunger has a first position in which the port is aligned with the second fitting body conduit to provide a first path and a second position in which the plunger second conduit is aligned with the fitting body first and second conduits to provide a second path.
