As NuGulf is looking towards major decommissioning operations, a Bureau of Safety and Environmental Enforcement-aligned Cased Hole Well Control Manual for Decommissioning Activity that is dedicated to the nearshore Gulf of America has been released.
The document focuses on decommissioning where the well is made safer, especially during the operation. The initial process involves establishing plug and cement barriers to isolate all hydrocarbon hazards. Once this step is achieved, well changes are determined by 'class' from pressure for flow potential to no pressure and no potential to flow. Equipment rig up can change from pressure tested PCE to 'open hole' operations to cut and pull tubing and casing.
This document comes after a tried and tested onshore Cased Hole Well Control Manual that ensured consistency in operations and both well site supervisors and contractors understand what is required for any cased hole operation.
A United States-based operator, NuGulf works to eliminate the global Asset Retirement Obligation (ARO) through the careful decommissioning, plugging and abandoning, and environmental cleanup of wells and field infrastructure. Their approach involves innovative solutions to efficiently deliver some of the most challenging decommissioning, well intervention and hurricane recovery projects.
