Completion Equipment
15-179 RTR Tension Release Sub

Product Overview

The RTR is a high performance tubing mounted device used to provide a fixed amount of expansion or contraction of the tubing between stacked packers. The RTR is ideal for use between hydraulic set packers that must be shear released by straight pull. By providing elongation in the tubing between the packers, the RTR allows each packer to be individually shear released with straight pull on the tubing. The RTR is shear pinned during deployment and the force at which the tool activates is fully adjustable. Once activated by straight pull in excess of the shear value installed in the tool, the RTR will elongate sufficiently to allow the packer directly above it to shear release and relax into the retrieving position. Once the packer is shear released the RTR will stroke to it’s limit and the next packer below may now be shear released in the same manner. As standard the RTR is manufactured form materials conforming to NACE MR0175 for H2S service.
