Model MST-CR Mechanical Setting Tools are used to mechanically set MSB-CR Sleeve-Valve Cement Retainers. This tool incorporates both a stinger seal and mechanical setting function. In addition, it has a built-in snap-latch, allowing the tool to be latched into the cement retainer with set-down weight and released with either upstrain or right-hand rotation. The sleeve-valve on the cement retainer is in the open position while being run in the well. When the setting procedure is completed, the sleeve-valve may be closed by picking up two inches at the tools or opened by slacking off two inches. The snap latch feature allows the sleeve-valve to be shifted open or closed while the tubing is still anchored to the retainer. Normally the valve is run open so the tubing may fill; however, for pressure testing the tubing, while running, the valve can be run closed. Cement Retainers can be set and pressure tested in a single trip.


  • Specially designed Bow Spring provides positive control and allows one size Mechanical Setting Tools to cover a large range of casing weight
  • The Upper slips are held in a safe retracted position while running
  • Allows users to set pressure test tubing, and squeeze in a single trip
  • Can quickly be configured to set MSB-CR Cement Retainers or MSB-BP Bridge Plugs
