Kazakhstan’s energy ministry has announced it will proceed with arbitration in a USD 13 bln dispute involving its partners in the Kashagan oil venture, which includes oil majors like Eni, Shell, Exxon Mobil, and Total. These companies have invested around USD 55 bln in the project and are being sued by the government for allegations of unauthorized spending. That underlines the complexities and risks of executing large energy projects under complex production-sharing agreements.
