The PetroQuip TTU Retrievable Bridge Plug is a high-pressure packer-style bridge plug used for multiple selective zone treating and testing operations.  The setting mechanism is compatible with the PetroQuip 1X packer for one trip multi-set plug-and-packer operations. The TTU Retrievable Bridge Plug will set in tension or compression, making it ideal for shallow applications such as wellhead testing, as well as for deep, high-pressure applications such as fracture stimulation.  The large internal by-pass prevents swabbing when running and retrieving.  The internal by-pass opens prior to releasing the upper slips to equalize pressure.
