Combined with Chrysaor’s existing portfolio first half of 2019 production averaged 195,000 boepd. The transaction adds two new operated hubs to Chrysaor’s portfolio in the UK Central North Sea – Britannia and J-Block – in addition to an interest in the Clair Field area.

With an effective date of 1 January 2018, completion of the transaction follows receipt of all necessary regulatory approvals.

Operator: ConocoPhillips (58.7%) Co-venturers: Chevron (32.3%), Mitsui (9.0%). Britannia is one of the largest Lower Cretaceous natural gas and condensate fields in the North Sea. Commercial production began in 1998.

The Britannia Gas Condensate Field in the Outer Moray Firth area of the UKCS is located 225 km northeast of Aberdeen at the triple junction of the South Viking, Witch Ground and Central Grabens. Hydrocarbons are trapped in Early Cretaceous (Late Barremian – Late Aptian) deepwater, marine turbidite sandstones in a combination stratigraphic/structural trap.
