AS1X Retrievable Packer

The Model AS1X Mechanical Production Packers is a retrievable, double-grip compression or tension-set produc tion packer that can be left in tension, compression, or in a neutral position, and will hold pressure from above or below.

A large internal bypass reduces the swabbing effect during run-in and retrieval, and closes when the pac ker is set. When the packer is released, the bypass opens first, allowing the pressure to equalize before the upp er slips are released.

Model AS1X Retrievable Packer also features a upper-slip releasing system that reduces the force required to release the packer.

A non-directional slip is released first, making it easier to release the other slips.

Run packer to setting depth.

Pick-up on the tubing and rotate 1/4 turn to the right at the packer.

Lower tubing to engage slips, release right-hand torque while moving tubing downward. (Tubing must be able to rotate back to the left at packer to lock into set position.)

Continue to set weight on packer to pack-off elements.

After setting weight on packer, pick-up on tubing and pull tension in packer to engage upper slips and complete element pack-off.

Repeat setting weight and pulling tension two to three times before landing tubing.

Packer may be landed in compression, tension or neutral position.

The releasing procedures are the same whether the packer has been tension or compression set.

Set-down weight (normally 1,000 lbs. is sufficient) on the packer and rotate the tubing 1/4 turn right at the packer, then pick-up holding the right-hand torque.

The internal by-pass will open, allowing pressure to equalize.

Further pick- up releases the releasing sequential slip system, relaxing the elements, allowing the packer to be removed from the well.

The packer can be moved and reset without tripping the pipe if the elastomers have not been permanently altered from the well environment.
