Suncor Energy, the world's second biggest miner from oil sands, has said that it has resumed full production after a fire two weeks ago caused a partial shutdown of its refining plant. The plant is producing about 200,000 barrels of oil a day after repairs were made to a hydrogen unit that removes sulfur and other impurities from the oil, Suncor said in a statement. Output this month will average about a hundred and eighty thousand barrels per day, down from more than 220,000 barrels in early April. Suncor mines oil laden sand that is then refined into a liquid near Fort McMurray in northeastern Alberta. The outage, and another caused by a power failure earlier this year, occurred in a section of the plant built last year as part of a C$3.4 billion ($2.16 billion) expansion. Shares of Suncor rose 43 Canadian cents to C$55.66 in Toronto. They have risen by twenty eight percent over the past year.
