The Casing Packer Setting Tool (CPST) provides a reliable method of deploying plugs and packers in the wellbore during completion, isolation, or abandonment.

The mechanical plug-back tool (MPBT) is used in through-tubing recompletions. Using a mast or a crane, could be used to run MPBT in case of rig less operation which both shall be provided by WSI. Recompletions can be accomplished without the cost of a workover rig. The anchored elastomeric plug is run through tubing and set in casing to plug off fluid flow in the casing below the plug.
