The AS1-X is a mechanically set retrievable packer that can be used in any production application. It is a single string, double-grip packer that can be set in compression or tension and holds pressure from above or below. The J-Slot design allows for easy ¼ turn right-hand set or ¼ turn right-hand release. Once set, the tubing string can be left in tension, compression, or in a neutral position. The AS1-X packer is very versatile and has an internal by-pass that reduces swabbing effects when run in or retrieved and closes when the packer is set. Upon release the bypass opens first and allows the pressure to be equalized. The standard design is made for pressures up to 7,000 PSI, a HT version is also available that is designed for differential pressures up to 10,000 PSI.
