HydrusMSTMMechanical Set Cement Retainers are deployed on Tubing or Drill Pipe and set by Snap Latch Setting Tool in compression. The large internal bypass prevents swabbing during running and retrieval. The bypass closes during Cement Retainer setting and opens during retrieval to enable pressure equalization before releasing the upper slips. The setting tool is released from the Cement Retainer by applying tension and back-up rotational release. The running string can be internally pressure tested before release.
HydrusWSTM Wireline Set Cement Retainers are deployed on Wireline and set via appropriate Wireline Pressure Setting Assembly (WPSA), Wireline Adapter Kit (WLAK) and Snap Latch Stinger Sub. When reaching the pre-determined depth, WPSA is actuated, the Tension Mandrel moves upward, pulling the body of the Cement Retainer up with respect to the setting sleeve of the WLAK, thereby setting and packing-off the Cement Retainer. Continued upward movement closes Control Latch inside the Retainer and the setting assembly with WLAK is retrieved once the Release Stud is sheared.
