Sustained Casing Pressure Remediation

Page last modified

April 11 2024

Resolv offers a novel method for SCP remediation. The Resolv fluid cures to form a compliant solid material, which is energised by a hydrostatic head to create a seal. The compliant nature of the cured material allows the seal to be maintained despite tubular contraction/expansion. The low initial viscosity of Resolv allows it to be applied using industry-available annulus intervention equipment, ensuring correct placement. Curing times can be tailored to suit the specific application. “Breakable” versions are available for cases where removal may be required.

Pros & Limitations

Creates seal in the well annulus to remediate sustained casing pressure

Compliant material can maintain seal despite tubular contraction/expansion

Can be deployed using industry-available annulus intervention tools

Can be supplied in a “breakable” form, allowing for future removal

Requires pressure from above to create pressure-retaining seal

Specification

Specification Title	Specification Description
Capabilities	Remediates SCP by creating a seal in the annulus.
Deployment	Can be deployed using industry-available annulus intervention tools.
Impact	Alternative approach to remediating SCP, reducing costs and risks, and potentially allowing shut-in wells to be brought back into production.
Flexibility	Curing time can be tailored to suit the application. Can be supplied as “breakable” system, allowing for removal.
Safety	Reduces requirement for bleed off operations.
