LONDON – ENGIE E&P UK has exported first gas from the Cygnus Bravo satellite wellhead platform serving the Cygnus field in the UK southern North Sea.
Last Tuesday, first gas flowed 7 km (4.3 mi) southeast from the platform to Cygnus Alpha, which has been producing at a plateau of 250 MMcf/d since last December. Commingled output then travels from Alpha, 150 km (93 mi) off the Lincolnshire coast, via a 55-km (34-mi) connection to the offshore Esmond Transmission System which lands at the Bacton gas terminal in Norfolk.
The Cygnus complex comprises four platforms and two subsea structures, with the Cygnus field extending across 250 sq km (96 sq mi). It currently supplies 5% of the UK’s gas production.
Maria Moraeus Hanssen, CEO of ENGIE E&P, said: “Gas from this second drill center will contribute significantly to extending the plateau production that Cygnus Alpha has been achieving for the last eight months.”
Bravo first gas came from well B5 in one of the platform’s 10 well slots, out of 20 across the entire Cygnus complex. A further three Bravo wells should start up next month, with five due to be available in 2018 following completion of well B1.
