Tengizchevroil declared force majeure on oil exports and cancelled five cargoes totaling up to 700,000 metric tons through February following a power plant fire that had halted production at Tengiz, the country's largest oil field, Reuters reported on Jan. 21. Concurrent with the shutdown, state authorities directed the diversion of crude from the Kashagan field to the domestic Shymkent refinery to compensate for ongoing throughput restrictions at the Caspian Pipeline Consortium.
