1
TD 005 — Severe corrosion & visual leak
Immediate
Conductor to starterhead system leak observed. Severe corrosion on tree and wellhead. Secondary barrier integrity at risk.
2
TD 002, TD 003, TD 005 — Sustained casing pressure
Weekly monitoring
SCP present on A-Annulus across three wells. Continue pressure monitoring and document trend.
3
TD 002, TD 003, TD 004 — Corrosion present
30 days
Mild to medium corrosion reported. Schedule corrosion assessment within 30 days.
4
TD 004 — Barrier failure, deferred mitigation
Per schedule
Mitigation status deferred. Confirm schedule and ensure secondary barrier is containing.
5
TD 003, TD 004 — Degraded barrier, enhanced monitoring
Ongoing
Both wells showing degraded barrier classification for 3+ months. Enhanced monitoring regime recommended.
