Statoil has resumed production from the Troll C platform in the North Sea following a temporary shutdown on Nov. 15 after inspectors found corrosion in some tanks on the auxiliary system for treating gas (OGJ Online, Nov. 15, 2012).
A team of experts decided to reinject untreated gas into the reservoir, enabling production to be restarted during late Nov. 17 and early Nov. 18.
“A great effort has been made during the weekend to plan the repair work, and we have also looked into alternative production methods,” said Rune Adolfsen, Statoil head of production on Troll C. “We assume that this method will allow us to produce at around 70% of full capacity during the repairs.”
Duration of the repair work has not yet been clarified.
Statoil has 30.58% interest in Troll field, and Petoro AS has a 56% interest. AS Norske Shell has 8.1% interest, Total E&P Norge AS 3.7% interest, and ConocoPhilips Skandinavia AS 1.6% interest.
