London - Serica Energy plc (AIM: SQZ), a British independent upstream oil and gas company with operations centred on the UK North Sea and over 80% gas production, provides the following update on its Columbus field, located in the Central North Sea.
We are pleased to announce that first production has been achieved from Columbus.
The well was opened into the Arran subsea system and hydrocarbons from the C1z development well started flowing on  November. The comingled Arran and Columbus production streams are now being exported to the Shearwater platform for processing and onward export to the gas and liquid sales points. Columbus is expected to be producing at its potential by Early December. Further information on flow rates will be issued as part of an Operations Update in mid-December.
Mitch Flegg, Chief Executive of Serica Energy, commented: 'I am delighted that first production has been achieved, as planned, during Q4 2021. This marks a significand milestone for Serica as it reaches the successful conclusion of its first development project. The Company was involved in the discovery of Columbus and has acted as Operator through the appraisal and development phases and now into operations. Serica's approach to increasing its production base and providing much needed energy to the UK, while seeking lower carbon emission solutions, has been achieved by using shared and existing infrastructure to progress the development of Columbus. I would once again like to acknowledge the skill, hard-work and dedication of our project team, the Shearwater and Arran Operators and our joint venture partners Waldorf Production UK Ltd. and Tailwind Energy Ltd.'

Serica Energy is a British independent oil and gas exploration and production company with a portfolio of exploration, development and production assets. Columbus lies 35km north east of the Shearwater production facilities and is being produced by a single well tied into the existing Arran to Shearwater pipeline. A recent Competent Person's Report estimates the Columbus gross undeveloped 2P reserves to be in excess of 14 million barrels of oil equivalent ('boe'). Following the recent drilling of the development well, it was connected to the Arran pipeline, through which Columbus production will be exported along with Arran Field production. When the production reaches the Shearwater platform, the gas and liquids will be separated, and the gas exported via the SEGAL line to St Fergus and the liquids through the Forties Pipeline System to Cruden Bay.
