The S1X/S1X-HP Double-grip Packer is able to set with tension or compression that holds pressure from above or below the packer. Once setting, the downhole string can be left in tension, compression or neutral situation. A large internal bypass can reduce the packer swabbing effect during running, retrieving, and closing when the packer is set.

When the packer is released, the bypass opens first to balance pressure before releasing the upper and lower slips. The S1X/S1X-HP packer also has an unique upper slip releasing system that reduces the force required to release the packer. With these flexible features the S1X packer can be used as production packer, bridge plug and stimulation packer.
