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

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