[LONDON] Oil rose towards US$46 a barrel on Wednesday as reduced production in Canada's oil sands region due to a wildfire pushed aside concerns about excess global supplies and expectations of rising US crude inventories.
The Canadian province of Alberta was evacuating the entire population of Fort McMurray where a wildfire took hold in the heart of the country's oil sands region, prompting some companies to cut output.
Brent crude was up 92 cents at US$45.89 at 1401 GMT. It reached a 2016 high of US$48.50 on Friday, but settled lower on that day and fell again on Monday and Tuesday. US crude was up US$1.17 at US$44.82.
"Oil prices could receive support from the wildfires in the Canadian oil province of Alberta," said Carsten Fritsch, analyst at Commerzbank.
Brent crude has fallen more than 5 per cent from Friday's high in response to rising output from the Organization of the Petroleum Exporting Countries, signs of economic slowdown in the United States and Asia, and a stronger dollar.
"It would not come as any surprise if speculative financial investors were to take profits against this news backdrop," Mr Fritsch added.
Canada's Suncor Energy, whose oil sands operations are closest to the city, said its main plant north of Fort McMurray, was safe, but it was reducing crude production in the region to allow employees and families to get to safety.
While total Opec output rose in April, outages around the world have been supporting prices. The Canada disruption adds to supply losses in Nigeria and Iraq, concern about renewed losses in Libya and fears that Venezuela's cash crunch could hit the Opec member's output.
Some in the market believe the rally has further to go in 2016 as the supply glut eases.
"Investor optimism for oil has markedly improved," said Nitesh Shah of ETF Securities. "We believe the gains in price are sustainable and not just driven by speculative gains." Nonetheless, increasing inventories suggest supply is more than ample for now.
A report on Tuesday from the American Petroleum Institute said US crude inventories rose by 1.3 million barrels. Stocks in the previous week were at a record high. Still, this was not as large as the 1.7 million-barrel increase analysts expected.
Later on Wednesday, the government's inventory report will be in focus for confirmation of the inventory move. The Energy Information Administration report is due at 1430 GMT.
