The Coiled Tubing Run Through Shear Sub has a standard safety shear and fish neck for use above a tension set packer. The bidirectional slip and seal set, above the shear mechanism, locks the shear sub and packer to the coiled tubing at any point. With this system, the tension packer, equipped with the Shear Sub is retained in the lubricator tube while the desired length of coiled tubing is run through the packer into the wellbore.
