Production

Natural Gas from Oselvar burns on the Ula platform flare on April 14th, 2012

Oselvar was developed with three production wells. Produced oil and gas was transported to the Ula field platform for processing via the Oselvar module. Once processed, the oil was pumped via the Norpipe system to Teesside, UK.[3] Although production was scheduled to start in November 2011,[1] production actually started on April 14, 2012.
