UK-based upstream oil and gas player Serica Energy has bolstered its long-term resource outlook by finalizing the acquisition of assets from the Netherlands-headquartered exploration and production entity, ONE-Dyas. This strategic move underscores Serica’s commitment to expanding its footprint in the North Sea region, a hotbed of hydrocarbon activity.
In September 2025, Serica disclosed the acquisition of ONE-Dyas’ 10% non-operated working interest in the Harbour Energy-operated Catcher field, alongside a 5.21% interest in the CNOOC-operated Golden Eagle Area Development (GEAD) fields situated in the Central North Sea. Valued at approximately $6.75 million, this acquisition signifies a robust addition to Serica’s existing asset portfolio.
Upon the completion of this acquisition, Serica highlighted the diversification of its producing portfolio, which boasts a current net production of around 2,500 barrels of oil equivalent per day (boepd). Notably, this deal brings in combined net 2P reserves of 3 million boe and an additional 2C resource of 0.5 million boe, as calculated on December 31, 2025.
As part of the transaction, Serica has finalized the set consideration of $6.75 million and has received an interim payment of $13 million. This payment reflects post-tax cashflows accrued between January 1, 2024, and the completion date, highlighting a favorable economic position for the company.
In a further twist to this acquisition saga, Serica will also gain around 85,000 barrels of oil equivalent linked to an underlift position, with cash proceeds expected to be approximately $8 million, slated for receipt in Q3 of this year.
This acquisition follows closely on the heels of Serica’s earlier deal involving assets from TotalEnergies in the West of Shetland gas fields, marking another significant enlargement of its operational footprint on the UK Continental Shelf (UKCS). The strategic acquisitions reflect Serica’s proactive approach in capitalizing on opportunities within the rapidly evolving landscape of the UK oil and gas sector.
