ExxonMobil's Japan refineries, which were shut down following the earthquake of 11 March 2011, are to restart as soon as possible.
The firm will restart its 335,000bpd Kawasaki refining complex as early as 17 March 2011, and will enter into full production a few days later, according to marketwatch.com.
A portion of the refinery is fully operational and will receive a petrol blend stock and other oil products from its refineries in Wakayama and Sakai, which are also operating at full capacity.
ExxonMobil is also taking steps to open the Chiba refinery run by its Japanese joint venture Kyokuto Petroleum.
More than a quarter of Japan's refining capacity has been offline since the earthquake.
