B-Annulus Monitoring System (BAMSE)
title
Continuous well integrity monitoring sensor for subsea wells
Reduce the risk of escalation of leakages to B-annulus
Monitoring of B-annulus is required by the Norwegian Petroleum Safety Authority: “Annulus should have pressure monitoring”
BAMSE eliminates the need for periodic testing of A-annulus for subsea gaslift wells;
Requires well shut in (12 hours ++, expensive)
Prone to error due to gas lift valve
Difficult to monitor leaks from production tubing to annulus
Benefits
No active electronics inside the wellbore and no moving parts
No penetration of the casing
Provides continuous monitoring and online data
