Kuwait hopes to get its Mina Abdullah oil refinery back to full production on Monday but the Shuaiba refinery is expected to take longer to return to normal after a power cut last week, the operator said on Sunday.

The 270,000-barrels per day (bpd) Mina Abdullah refinery was running at about 60 percent of capacity on Sunday, a spokesman for state-run Kuwait National Petroleum Company (KNPC) said.

The 200,000-bpd Shuaiba refinery was running at just over 70 percent of capacity on Sunday. But it will take longer to return to full output because Shuaiba is an old plant, he said.

The Opec member has been using fuels held in storage to maintain exports while the three refineries that were shut down by the power fault return to full flow.

The January 22 power outage shut down all three of Kuwait's refineries.

KNPC returned the 460,000 bpd Mina Ahmadi refinery back to full production early on Friday. - Reuters
