Operations at the Balongan Refinery are on hold while firefighters continue to battle the blaze. Police suspect the explosion was triggered by lightning.
Indonesian state oil company Pertamina said on Monday that it hoped to restore operations at its facility in four or five days following a massive fire and explosion that forced almost a thousand people to be cleared from the site.
Pertamina shut down the Balongan plant, which has a refining capacity of about 125,000 barrels of crude oil a day.
Located about 225 kilometers (140 miles) east of Jakarta, it supplies fuel to the capital city, as well as Banten and some regions of West Java.
