North Sea Triton drilling campaign enters final phase

Production through the Triton FPSO in the UK North Sea continues to rise following the recent startup of the Gannet field GE05 well, Serica Energy said in a Jan. 21 operations update.

The well has been producing oil at a stabilized rate of more than 6,000 bbl/d. The next planned tie-in is the W7Z well on the Guillemot North West field, which should enter production in February.

The COSL Innovator semisub rig has since spud the potentially high-impact EV02 well on the Evelyn field, and this looks set to go onstream during the second quarter.

In April, the rig is due to start drilling the BE01 well on the Belinda field, which should produce from early next year following the installation of subsea infrastructure. That will conclude the current five-well campaign in the Triton area.

Around the Bruce/Keith/Rhum hub area in the northern North Sea, Serica continues to mature new development opportunities, notably on the Bruce field.

On the Bruce platform, the company has altered the operating mode of the oil export pumps, and changes have been made at Rhum to the subsea pipeline system that should deliver increased reliability. The latter work led to production from the R3 well being suspended for three weeks recently.

For 2025 as a whole, Serica has budgeted roughly $330 million of opex and $220 million to $250 million capex, much of it related to the Triton drilling and subsequent work at Belinda.

Following the UK government’s decision to retain the first year allowances in the October budget, the company has accelerated resilience enhancement measures at the Bruce hub and Triton FPSO.

It will also pursue a $10 million flare gas recovery project at Bruce, which should qualify for the decarbonization allowance.

But Serica expects only limited spending on the NEO-operated Buchan Horst hub development in the central North Sea, as it waits for clarity concerning the UK’s long-term fiscal regime for petroleum investments and guidance concerning future environmental impact statements.
