Engie E&P UK Ltd. and its partners, Centrica and Bayerngas, have achieved first gas production and export from the Cygnus Field in the Southern North Sea.

The four-platform complex has 10 wells and two subsea structures. Plateau production is expected to be 250 MMcf/d. Gas from the development is being exported to the Bacton gas terminal in North Norfolk, the company said.

“First gas from Cygnus represents a significant boost to the UK’s long term energy security, with an estimated production life exceeding 20 years,” said Ruud Zoon, managing director for Engie E&P. “Furthermore, with over 80% of the contract work secured by British businesses—including fabrication yards in Hartlepool, Methil and Burntisland—it is a showcase for the technical and commercial excellence of the UK oil and gas supply chain.”

Cygnus is located in license areas P1055 and P1731. It is expected to contribute 5% of U.K. gas production, Engie said.

The partners are evaluating additional opportunities in the Greater Cygnus area in hopes of adding volumes through Cygnus when capacity becomes available, the company said.

Engie is the operator with 38.75% interest. Partners Centrica and Bayerngas hold 48.75% and 12.5%, respectively.
