AS1X Retrievable Packer
AS1X Retrievable Packer
Description
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.
Features
1. Holds high pressure differentials from above or below.
2. Can be set using tension or compression.
3. Only one-quarter right rotation is required to set and release.
4. Field-proven releasing system.
5. Optional safety-release features available upon request.
6. Elastomer options available for hostile environments.
7. Bypass valve is below upper slips so the debris is washed from slips when the valve is opened.
Operation Instructions Of AS1X Retrievable Packer
Running of AS1X Retrievable Packer
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.
Retrieving of AS1X Retrievable Packer
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.

Operational Capabilities And Environmental Tolerances
①Temperature Rating:
This indicates the range of temperatures in which the AS1X Retrievable Packer can operate effectively. The packer is designed to function in three different temperature ranges:
- ≤120℃ (Low temperature range)
- 120℃-170℃ (Medium temperature range)
- 170℃-204℃ (High temperature range)
This wide temperature range allows the packer to be used in various well conditions, from relatively cool to very hot environments. The ability to operate at temperatures up to 204℃ (approximately 400°F) makes it suitable for many high-temperature well applications.
②Casing Grade Range:
This specification describes the types and strengths of casings that the AS1X Retrievable Packer is compatible with:
- ≤Q125: This indicates that the packer can be used in casings with grades up to and including Q125. Q125 is a high-strength casing grade often used in demanding well environments.
- H2S & CO2 Resistant Casing: This means the packer is designed to be used in casings that are resistant to hydrogen sulfide (H2S) and carbon dioxide (CO2). These gases can be highly corrosive, so using resistant casings and compatible equipment is crucial in wells where these gases are present.
