A trio of international law firms have won roles on a $1.6bn (£1.0bn) Russian energy deal as Gazprom moves to grow its share of the market.

Cleary Gottlieb Steen & Hamilton has advised Gazprom on the deal, which closed last week (23 September) and saw the Russian energy giant buy a 51% stake in SeverEnergia from Italian utility companies Enel and Eni.

Enel was advised by Salans, while Eni instructed magic circle firm Freshfields Bruckhaus Deringer.

Freshfields partner Jacky Baudon lead the firm's team in Moscow, alongside senior associates Sergei Diyachenko and Ekaterina Dorokhina.

Moscow and Paris-based capital markets partner Russell Pollack was the lead partner at Cleary for Gazprom, while Moscow-based partner Jane Tarassova led the team for Salans. The Salans team also included London corporate head Paul Salmon and lawyers from the firm's New York and Paris offices.

Eni and Enel purchased the SeverEnergia stake during the 2007 Russian bankruptcy auction of the assets of Yukos. Following the deal with Gazprom, Enel's stake in the company has reduced from 40% to 19.6%, while Eni's has dropped from 60% to 29.4%.

The deal comes after Gazprom's $4.2bn (£2.6bn) purchase of a 20% stake in its oil unit Gazprom Neft (formerly Sibneft) from Eni in April. Cleary also advised Gazprom on that deal, while Eni turned to Dewey & LeBoeuf City partner Dan Coppel and Moscow partner Jon Hines.
