Engineered for Precision
Compact yet powerful, the PMBP uses a mechanical conversion system that turns external pressure into additional sealing force, ensuring secure isolation even under high differentials.
- Operates in coil tubing, drill strings, and restricted bores
- Withstands up to 7,500 PSI at 350ºF (HSN elements)
- Available in five sizes, covering ¾ (19.05mm) to 1.75” (44mm)
Other element materials (Viton and Aflas) are available upon request. Each PMBP also includes a pump-through check valve option for added versatility.
Application
Versatile, compact, and built for performance, the PMBP is a trusted choice for multiple downhole operations.
Pressure Control
Reliable control for snubbing operations or temporary isolation.
Barrier
Acts as a mechanical barrier to replace failed downhole components.
Retrieval
Ideal for coil tubing retrieval, providing a secure mechanical seal.
Cleanout
Enables coil tubing cleanouts and nitrogen purges via pump-through capability.
Compact Design. Reliable Isolation.
The Avalon PMBP (Permanent Miniature Bridge Plug) is engineered for restricted ID environments such as coiled tubing and small-bore tubing strings. The seal system is designed to maintain integrity across internal coil tubing seams. Optional pump-through check valves allow tubing to be purged or fluids displaced after the plug is set.
Designed for Small-Bore Conditions
The PMBP’s small outer diameter allows smooth deployment through restricted tubing while maintaining a fluid-tight seal against the tubing wall. It’s the ideal choice for high-pressure, high-temperature, or critical sour operations.
Select plug size based on actual tubing or pipe I.D.
Always verify coil tubing drift and weld conditions
Double barrier (two plugs) is recommended for safety-critical work
Specialized miniature cement bailer systems available for extreme operations
Built on Experience, Proven in the Field
With decades of design refinement behind it, the PMBP offers the perfect balance of precision engineering and rugged dependability, so you can trust it to perform when space, pressure, and temperature leave no margin for error.
