Cleanup efforts are underway at a Murphy Oil pipeline after the company detected a 17,000 barrel condensate spill Monday at its Seal heavy oil site in Northern Alberta.
The Arkansas-based firm said the spill was detected on March 1 after condensate was found in three areas around the site.
Initial estimate pegged the spill size at 94 barrels but on Monday the company discovered the spill was much larger, the Canadian Press said.
The company said the spill happened over an extended period of time but is still investigating the size and duration of the leak.
The spill happened about 80 miles southeast of Peace River, Alberta.
The Alberta Energy Regulator said there have been no reports of environmental or wildlife damage.
The pipeline has been isolated and depressurized and cleanup has begun.
