Serica Energy has completed the purchase of minority stakes in two producing North Sea assets from ONE-Dyas, adding output, reserves and resources to its UK Continental Shelf portfolio.
The deal includes a 10% non-operated working interest in the Catcher field, operated by Harbour Energy, and a 5.21% interest in the Golden Eagle Area Development fields, operated by CNOOC. The transaction, first disclosed in September 2025, was valued at $6.75 million.
With completion now confirmed, Serica Energy gains around 2,500 boepd of current net production. The acquired interests also bring net 2P reserves of 3 million boe and net 2C resources of 0.5 million boe, based on figures as of 31 December 2025.
The company paid the agreed $6.75 million consideration and received $13 million for interim post-tax cashflows covering the period from the economic date of 1 January 2024 to completion.
Serica Energy will also receive about 85,000 boe linked to an underlift position. Cash proceeds from this are expected to reach approximately $8 million in Q3.
The transaction follows Serica Energy’s recent addition of interests in West of Shetland gas fields and related assets from TotalEnergies, further expanding its position in UK waters.
