BP's Russian joint venture TNK-BP has agreed to sell Gazprom its 62.89% stake in Rusia Petroleum, the firm with the licence for the Kovykta gas field.
TNK-BP will also sell its half-share in East Siberian Gas Company, the company constructing the regional gasification project, BP said in a statement.
Gazprom will pay from $700m to $900m (£350m-£450m), for the TNK-BP stakes.
