Zennor purchased Mitsui’s 8.97% stake in the Britannia Field in 2018. Britannia, discovered in 1975 and on-stream in 1998, currently produces around 25,000boepd gas-condensate from Lower Cretaceous sandstones via over 30 production wells. The purchase doubled Zennor’s net production and is linked to Zennor’s nearby Finlaggan development.
