Serica Energy announced that, following a successful ramp-up which helped wider portfolio production reach over 55,000 boepd in mid-August, the operator of the Triton FPSO, Dana Petroleum, has notified Serica of a temporary reduction in oil production while further maintenance takes place. In addition to the above, Dana has also notified the Company that subsea intervention work on the Bittern field has been scheduled for November 2025.
The resultant production deferrals mean that Serica’s production guidance for 2025 has been reduced to 29,000 to 32,000 boepd (previously 33,000 to 35,000 boepd). Due to a vibration issue within the compression trains on the Triton FPSO, production is currently running at a significantly reduced rate. Following the required repairs, normal production operations are expected to resume around the end of September.
Work is currently ongoing to deliver two compressor operations, which will facilitate the full ramp-up of production at the FPSO. Production net to Serica from the Triton FPSO has reached over 25,000 boepd in August, and running with two compressors can deliver an increase from this figure through the addition of production from the EV02 well on the Evelyn field. Work on the Bittern field subsea infrastructure, which is scheduled to take three weeks to complete, is to address an emerging vulnerability.
The work scope had previously been removed from the outage in summer 2025 and was expected by Serica to be completed in 2026, but the operator has now confirmed that it will take place in November this year. Given the location of the pipework, in addition to the Bittern field this will also halt production from the Evelyn and Gannet fields, resulting in a temporary reduction of over 20,000 boepd net to Serica.
