The Full Bore Retrievable Packer is with mechanical setting, and used for drill stem testing
The RTTS Packer is a full opening, hookwall type packer which can segregate bidirectional pressure designed for use in testing, treating, and squeeze cementing operations. The full opening permits pumping large volumes of fluid with a minimum pressure drop, and allows the passage of a through tubing type perforating gun. This helps make the tool usable for multiple operations with one trip in the hole-such as perforate, test, treat, squeeze, perforate, etc. Generally, the tool is composed of a packer body assembly and circulating valve assembly. It may also includes a safety joint.
The packer body includes a J-slot mechanism, mechanical slips, packing element, and hydraulic slips. Large, heavy-duty slips are used in the hydraulic hold-down mechanism and help prevent the tool from being pumped up the hole. The packer is equipped with the drag block.
