Husky Energy has reported a major hydrocarbon gas release from subsea equipment on its White Rose development.
According to the Canada-Newfoundland & Labrador Offshore Petroleum Board (C-NLOPB), the release happened on 31 August from the southern drill center at White Rose and was shut off within 12 minutes of the initial alarm.
Husky estimates that 8938kg of natural gas was released to the sea during the incident, says the C-NLOPB. The Atlantic Osprey was mobilized to the southern drill center to investigate with a remotely operated vehicle (ROV).
The C-NLOPB is reviewing the incident and Husky is continuing its investigation.
White Rose was developed using subsea technology with three drill centers tied back to the SeaRose floating production, storage and offloading vessel. Subsea wells in the southern and central drill centers produce, while surplus gas is reinjected in to the northern drill center for future extraction.
Husky is considering a White Rose extension project, to assess developing resources in the West White Rose Pool using a well head platform tied back to the SeaRose. However, a final investment decision on the project was deferred in Husky's 2015 business plan.
