RIL and British Gas Exploration and Production India Ltd (BGEPIL) filed for arbitration in December 2010, in the wake of differences with the government over issues such as cost recovery and profit-sharing. ONGC was not party to the case. BGEPIL's stake in the field was taken over by Shell in a deal that followed one between the parent groups BG Group Plc and Royal Dutch Shell Plc in February 2016.
