Gas Environment Retrievable Packers
Overview
ANVEY V0‑GASLOCK™‑55 Hydraulic Production Packer
Hydraulic‑set • Large‑bore • Removable • V0‑rated for gas‑tight integrity
The ANVEY V0‑GASLOCK™‑55 is a next‑generation hydraulic‑set, large‑bore production packer engineered to deliver permanent‑packer performance with the operational flexibility of a retrievable system. Designed specifically for 5½" casing, it provides zero‑bubble gas sealing, secure tubing anchoring, and dependable well control across the full operating envelope.
With its AFLAS® gas‑decompression‑resistant sealing system and a metal‑to‑metal by‑pass incorporating a soft‑metal interface, the V0‑GASLOCK™‑55 achieves true V0‑class isolation, preventing gas migration up the annulus and protecting personnel, equipment, and the environment.
Why Choose GASLOCK™‑55?
Engineered for High‑Performance Completions
The V0‑GASLOCK™‑55 is ideally suited for:
- Big‑bore production strings requiring maximum ID
- Stacked‑packer multizone completions
- High‑pressure gas wells where RGD resistance is critical
- Liner‑top isolation
- Monobore and single‑selective completions
- Extended‑reach and deepwater wells where intervention costs are high
Its modular architecture allows the packer to be run directly on the production string or paired with an anchor‑seal assembly, enabling tubing retrieval without disturbing the packer.
Setting and Retrieval
- One‑trip hydraulic setting is achieved by applying pressure against a plugging device below the packer.
- Retrieval options include:
- Mandrel cut using chemical or mechanical cutters
- Shift‑to‑release mechanisms
- Shear‑release options for medium‑service applications
This flexibility reduces intervention time and cost while maintaining high operational reliability.
