Serica Energy plc has reduced full-year guidance following more issues with the Triton floating production storage and offloading unit, and intervention work in November on the Bittern field.
COMPRESSORS
The FPSO has a “vibration issue” within the compression trains, resulting in a “significantly reduced rate” of production.
Partner and operator Dana Petroleum, which increased production in mid-August to more than 55,000 barrels of oil equivalent per day, will temporarily reduce production for maintenance work.
“Following the required repairs, normal production operations are expected to resume around the end of September,” said Serica.
“Work is currently continuing 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 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.”
The Bittern field’s subsea infrastructure will undergo intervention work, expected to last three weeks, 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,” added Serica.
“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.”
Serica said that 2025 guidance had decreased from 33,000 to 35,000 boepd to 29,000 to 32,000 boepd.
