NCOC seeks arbitration over sulphur fine
The North Caspian Operating Company (NCOC), which operates the huge Kashagan oil field in Kazakhstan, has said that it is seeking international arbitration to resolve its ongoing dispute with the government of Kazakhstan. Kazakhstan has imposed a swingeing $4.6 billion fine for alleged violations of sulphur storage regulations at the NCOC site. In December, a special administrative court in Astana turned down an appeal by NCOC, although it also granted leave to appeal in a higher court. NCOC, a partnership between Shell, Eni, TotalEnergies, ExxonMobil, China National Petroleum Corporation, Inpex and Kazakh state oil and gas company KazMunayGaz, continues to maintain that its sulphur handling operations have been conducted in compliance with Kazakhstan’s laws and that it had the required permits in place.
