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.
