Confirm a reliable seal in HP/HT conditions
BRIMSTONE HP/HT Well Barrier Confirms gas-tight wellbore isolation in HP/HT conditions.
The Baker Hughes BRIMSTONE high-pressure, high-temperature (HP/HT) well barrier is a high performance drillable bridge plug that is commonly used for zonal isolation during stimulation or cementing jobs, or for temporary and permanent well abandonment. It is ISO 14310 V0-rated and capable of withstanding 25,000 psi (1723.6 bar) differential pressure at 500°F (260°C).
It can be quickly and accurately deployed on wireline using a Baker Hughes HP/HT nonexplosive hydrostatic setting tool or an E-5 wireline pressure setting assembly or on coiled tubing with a HPHT J hydraulic setting assembly. The BRIMSTONE well barrier is manufactured of carbon steel and can be removed using Baker Hughes Advanced Milling Technology (AMT) cutting structures.
The BRIMSTONE barrier is part of the Baker Hughes STONE WALL V0-rated barrier portfolio—a comprehensive suite of tools that ensures gas-tight isolation throughout the well’s lifecycle.
Applications
- Zonal isolation during stimulation or cementing;
- Isolation of shoe track;
- Temporary or permanent well abandonment;
- HP/HT environments.
Features and Benefits
- Wireline or coiled tubing set:
? – Enables flexible deployment and operation.
- V0 gas rating above and below the tool at up to 500°F and 25,000 psi differential:
? – Provides high performance in HP/HT environments.
- Increased clearance:
? – Allows faster, safer run-in using packing element that prevents swab-off forces.
- Body lock ring:
? – Traps setting force in packing element to maintain optimal seal against pressure reversals.
- Anti-rotation mechanism:
? – Increases removal efficiency, saving removal cost through time and material.
TOMBSTONE: Ensure a permanent barrier for well plug and abandonment
TOMBSTONE Permanent Well Barrier Confirm a reliable, V0-rated barrier for P&A operations.
During well abandonment, operators often face issues with gas migrating into the cement before the cement can set, which can lead to serious HSE concerns and failure to properly plug and abandon (P&A) the wellbore.
The Baker Hughes TOMBSTONE permanent well barrier is validated to ANSI/API 11D1 ISO 14310 V0 standards at 10,000 psi from 40-250°F (4-121°C) to ensure a gas-tight barrier. Eliminating gas migration into the cement helps reduce the cost and time associated with re-cementing, which is especially important during P&A operations. The TOMBSTONE barrier offers ?exible deployment options using wireline, tubing, or coiled tubing.
The barrier’s superior design increases the clearance space between the tool and casing for faster, safer run-ins. And, if removal is needed, the unique top venting design allows for the upper portion of the barrier to be drilled out, permitting pressure equalization across the tool before drilling out the upper slips.
