An expansion project is associated with the Cygnus, namely the Cygnus Development. This project is currently in the approval stage, expected to start in 2023.

Field participation details

The field is owned by Centrica, Neptune Energy Group and Stadtwerke Munchen.

Production from Cygnus

The Cygnus conventional gas field recovered 54.48% of its total recoverable reserves, with peak production in 2020. The peak production was approximately 0.96 thousand bpd of crude oil and condensate and 256.00 Mmcfd of natural gas. Based on economic assumptions, production will continue until the field reaches its economic limit in 2042. The field currently accounts for approximately 3% of the country’s daily output.

Remaining recoverable reserves

The field is expected to recover 71.63 Mmboe, comprised of 0.70 Mmbbl of crude oil & condensate and 425.55 bcf of natural gas reserves. Cygnus conventional gas field reserves accounts 0.02% of total remaining reserves of producing conventional gas fields globally.
