Serica Energy completes acquisition of Southern North Sea assets from Spirit Energy

Type: Acquisition · Technology: Oil Gas · Country: United Kingdom · Value: $43M · Announced: 2026-10-01

Serica Energy completed the acquisition of a portfolio of Southern North Sea assets from Spirit Energy on 2026-10-01 for a net payment of $43 million, reflecting upfront consideration of $75 million reduced by post-tax cash flows between 2025-01-01 and completion. The acquired portfolio includes a 15% non-operated interest in the Cygnus gas field, a 25% non-operated interest in Clipper South, operated positions across the Greater Markham Area and other Southern North Sea gas interests, and 3.4 million boe of 2C resources as of 2025-01-01. Serica forecast the assets will add around 10,000 barrels of oil equivalent per day of production and 18.7 million boe of proved and probable reserves, with the portfolio now expected to generate more than $200 million of free cash flow by the end of 2028. Spirit Energy is retaining decommissioning liabilities related to the operated assets, which are expected to represent more than 75% of the portfolio's total estimated decommissioning liability. Serica will report production from the acquired portfolio as its Southern North Sea Hub and attributed the improved cash flow outlook to a stronger gas price outlook and rephasing of some production into the post-completion period.
