Gas Environment Packers
Overview
The ANVEY V0-GASLOCK™-55 Hydraulic Production Packer is a state-of-the-art solution designed for efficiency and reliability. This hydraulic-set, large-bore production packer offers the durability of a permanent packer combined with the flexibility of a retrievable system. Specifically engineered for 5½" casing, the V0-GASLOCK™-55 ensures zero-bubble gas sealing, secure tubing anchoring, and effective well control throughout its operating envelope. Featuring an AFLAS® gas-decompression-resistant sealing system and a metal-to-metal bypass with a soft-metal interface, this hydraulic production packer achieves true V0-class isolation, preventing gas migration up the annulus while safeguarding 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.
