STONE WALL V0-rated well barriers

Get assured mechanical wellbore isolation for all of your operational needs with the STONE WALL™ V0-rated well barrier portfolio from Baker Hughes. Whether you are drilling, completing, producing, or abandoning your well, our comprehensive suite of well barrier tools gives you complete well control to ensure safe operations and environmental protection.

Reliable isolation for every well application

Each barrier in our STONE WALL portfolio undergoes a stringent testing process, validated to stringent ANSI/API 11D1 ISO 14310 V0 standards. This ensures a robust barrier in a wide-ranging applications.

Obtain reliable, temporary well suspension with the CROWNSTONE™ GTV tubing-retrievable well barrier. A dependable barrier for temporary suspensions such as casing evaluation, wellhead testing, and hurricane plugging, the CROWNSTONE GTV includes:

• A packing element configuration for increased reliability if debris is trapped on top of the barrier
• A sure-test feature that enables pressure tests above and below the barrier to ensure pressures are controlled prior to retrieval
• A unique design that eliminates the need for additional weight to set the barrier

Achieve short-term isolation and ensure smooth retrieval operations with the CAPSTONE™ wireline-retrievable well barrier.  The CAPSTONE well barrier delivers an economical solution for temporary isolation ahead of well servicing or surface equipment repair. Other features include:

• Streamlined design for increased running speeds and trouble-free retrieval
• Field-proven components that eliminate premature unsetting and improve reliability
• Compatibility with industry-standard setting tools for greater flexibility and reduced operational costs

Confirm a reliable seal in high-pressure/high-temperature (HP/HT) conditions with the BRIMSTONE™ HP/HT well barrier.  With confirmed zonal isolation in environments up to 25,000 psi (1723.6 bar) differential pressure and 500°F (260°C), the BRIMSTONE well barrier also provides:

• Quick and accurate deployment on wireline or coiled tubing
• A body lock ring to maintain optimal seal against pressure reversals
• Assured reliability in extreme conditions

Ensure a permanent barrier for well plug and abandonment with the TOMBSTONE™ permanent well barrier. By providing reliable wellbore isolation during final P&A operations, the TOMBSTONE well barrier also delivers:

• Assured, total isolation that blocks any gas from migrating uphole at the end of the well’s lifecycle
• Flexible deployment options for improved operational efficiency
• A gas-tight seal that mitigates gas migration into cement, avoiding cost and time associated with re-cementing
• A top-venting design that allows for pressure equalization across the tool and prevents kicks while drilling out upper slips
