Well Integrity Exposure Matrix
Traditional well integrity status has limited use when not considering well type or well flow potential.
Automatic Valve Testing
Aker BP noticed how the current logging av valve tests was conducted inefficiently, and with possibilities for human error.
Location-based Well Integrity Management
A Middle-East operator with large number of onshore wells were looking to save man-hours and minimize well risk.
Deepwater Blowout Preventer (BOP) Reliability & Well Kicks
2010 blowout and subsequent spill from the Transocean Deepwater Horizon Mobile Offshore Drilling Unit(MODU) in the US Gulf of Mexico Outer Continental Shelf (OCS))
Failed XMT Valves – Shut-in or Continue Production?
Two mature fields in the NCS optimizes reservior drainage through remote subsea installations. Subsea installations has historically lower ability for testing and verification of well barriers.
Robust Well Design Required for High Impact Wells
Gas field development with high Impact subsea wells, serving 20% of the UK gas market. Project focused on high reliability wells, with low forecast on intervention activities.
Minimizing Intervention Costs in Field Development
Subsea field development offshore Ghana optimizing intervention frequency. Equipment failures and intervention activities in the operational phase has high risk and cost.
Stuck Safety Valve on High Rate Subsea Oil Producer
A downhole safety valve was stuck in the open position on a high rate subsea oil production well. The options were to temporarily close the well or continue to operate it with the valve open.
Annulus Safety Valve Repair
Regulations in a key oil producing region dictated all gas-lifted wells have annulus safety valves. One producer had many wells with failed ASVs, which would have required expensive repairs and shut-down.
Gas Lift Valves As Barrier Devices
Because gas lift valves were considered primary well barrier devices by a North Sea producer, it was necessary to test these valves on a prescribed schedule. The costly and dangerous testing procedure involved well intervention and setting plugs to discover potential leaks.
