RTTS Packer for 9 5/" Casing, working pres. 70Mpa, Temp. upto 400F, full bore type, mechanical setting with J slot, Hydraulic holddown body and slip

The RTTS Packer is a full opening, hookwall type packer which can segregate bidirectional pressure designed for using 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 useable for multiple operations with one trip in the hole- such as perforate, test, treat, squeeze, reperforate, etc. Generally, the tool is composed of a packer body assembly and circulating valve assembly. It may also include a safety joint.
The packer body includes a J-slot mechanism, mechanical slips, packing elements, and hydraulic slips. Large, heavy-duty slips are used in the hydraulic hold-down mechanism and help to prevent the tool from being pumped up the hole. The packer is equipped with the drag block.
