PSA initiates probe of Statoil for well barrier designs


Back in March, a well kick resulted from a drilling operation that was carried out by a probe from Norway’s Petroleum Safety Authority. As a result, Statoil is now under fire by The Petroleum Safety Authority (PSA) for their breaches that seem all too common for the company.

It’s reported that after washing, the volume began rising due to the seawater ingress, causing the well to shut and use a blowout preventer valve. During this process, it was found that both valves were jammed, preventing normal kill procedures.

The PSA investigative report states, “The investigation has identified non-conformities relating to the design of well barriers, verification of well barriers, classification of safety-critical equipment, the maintenance programmed for kelly cock valves and the configuration of the seabed BOP.”

Statoil’s deadline to respond to the investigation is August 18.
