Double grip retrievable packer


The M1-X Casing Packer is a mechanical set, retrievable casing packer used in well testing, injection and production applications.

The Packer features an internal bypass to reduce swabbing during the trip in and out of the well. The bypass closes during setting and opens before releasing the slips to equalize pressure. The packer can be set with the tubing in tension or compression and can be left in compression or tension after setting. The ability to set the packer with tension makes the M1-X ideal for shallow wells. The Packer is set and released by a quarter right-hand turn at the tool.
