Capex effective p&aUsing V0 1214WAB as base for reduced risk P&A
The WAB was positioned close to the 13 3/8” shoe, to form part of the barrier envelope.
Exposed formations below the 13 3/8” csg shoe increased the risk of gas migrating and resulting in a gas below well head causes problems during PP&A. IS0 14310 V0 leak rate qualification of the WAB permitted installation without dispensation from the authorities. Next step was to drill out across the reservoir section to 8 1/2" open hole.
Primary & contingency liner
Plug & abandonment
1. Ensuring no SCP within the B annulus and as a base
2. As a future base for cement during well abandonment
After a successful well test, a bridge plug was installed inside the 9 5/8” casing just below the WAB depth. The 9 5/8” casing was then cut and the bridge plug and WAB were tested to 70 bar above 13 3/8” LOT. Cement was pumped to provide the necessary seal integrity to met the regulatory requirements for well abandonment.
CAPEX effective, reduced risk P&A operations.
Enhanced well integrity and extended reservoir contact via IS0 14310 V0 rated WAB portfolio.
Through its versatility in application and robustness in design, the WAB (Welltec Annular Barrier) for well completions can be utilized to provide solutions, to many requirements throughout the completion phase of a well.
