Thru-Tubing Inflatable Cement Retainer

The Thru-Tubing Cement Retainer (TTCR) allows permanent isolation and cementation of a lower zone without pulling the production tubing and packer. The built-in retrievable spotting valve provides a means of spotting cement to the top of the tool so unwanted fluids are not pumped into the formation. Because the retainer and spotting valve operations do not require rotation, the tool can be run on coiled tubing as well as threaded tubing.
