Norwegian pipeline firm Solveig Gas has agreed to buy oil firm Capricorn Norge from Cairn Energy for $100 million, completing its transformation into a North Sea field operator, Solveig's owner HitecVision said on Nov. 27.

The private equity fund told Reuters earlier this year it aimed to turn Solveig into an integrated exploration and production company, using the cash flow from its gas pipelines to fund expansion.

Cairn separately confirmed the deal, adding it will use the proceeds to fund its ongoing oil business in British waters.

Capricorn owns 10% in the Wintershall Dea-operated Nova field in the North Sea, and plans to drill two exploration wells in 2020, HitecVision said in a statement.

“The acquisition of Capricorn is expected to provide production of approximately 6,000 barrels of oil equivalent per day from the Nova field when production commences in 2021 and will give Solveig the competence to act in the role as an operator for exploration licenses in Norway,” it said.

Solveig Gas owns 15.56% of the Norwegian Gassled pipeline and terminals joint venture, and is the second largest owner after government license holder Petoro, which owns 46.7%.

The company also 13.3% of the Polarled in the Norwegian Sea, and 10% of the Neptune Energy-operated Duva field in the North Sea.

HitecVision also owns a 30.4% stake in Vaar Energy, with Italy's Eni holding the rest. Vaar was formed last year by merging Eni’s Norwegian operations with assets HitecVision had bought from Exxon Mobil.
