Wildfires in Alberta are threatening almost half a million barrels of daily crude production as heat and wind push the flames closer to massive oil sands well sites.

A total of 29 out-of-control fires are burning in the province amid hot, dry weather, bringing flames within 20 kilometers (12 miles) of about 459,000 barrels of daily oil production, according to data from Alberta’s energy regulator and wildfire department. The province had only four out-of-control fires on Monday.
