Expandable Bridge Plugs
A valve system with a sealing element providing bidirectional sealing and anchoring.
Advantages
- used for temporary isolation of a well interval;
- expansion ratio up to 1:2, suitable for running through production-casing restrictions to set in the liner;
- retrievable if required;
- run and retrieved on wireline or CT/tubing;
- set using a dedicated setting tool.
Specifications
- differential pressure rating: up to 35 MPa
- temperature: up to 175 °C
- seal material: HNBR/Viton
- size range (production casing): 114 to 140 mm
Application area and experience
The expandable bridge plug is designed for temporary or permanent shut-off of the wellbore (interval isolation). Set in the casing, it expands to fit tightly against the walls, creating a leak-tight barrier. Used in remedial isolation work, zone shut-off, testing and well abandonment.
