Annular Safety Valve (ASV) Packer

Annular Safety Valve V0 rated (bubble tight) Packer

Continuous gas injection with enhanced well integrity

 

The ASV packer provides the V0 rated barrier required to contain the lift gas present in the A annulus of a gas lifted well.

 

 

Challenge

Gas lifted wells typically have a large volume of explosive lift gas contained in the A annulus of the well. Major damage to the wellhead can result in the uncontrolled escape and ignition of the lift gas with catastrophic consequences for both personnel and equipment. Designing a retrievable ASV packer capable of containing the lift gas over the life of the well has been a major challenge for the industry.

 

 

Solution

Petroleum Technology Company’s ASV packer features a solid mandrel design with cut to release functionality, providing a gas tight barrier in an easily retrievable packer.
