On the afternoon of July 15, 2015, an emulsion leak from a pipeline was discovered within Nexen’s Long Lake operations, located south of Fort McMurray.
The incident involves a pipeline carrying emulsion from our steam-assisted gravity drainage (SAGD) operation at Kinosis to the Long Lake plant.
Emulsion is a mixture of bitumen, produced water, and sand.
Our emergency response plan has been activated and our response personnel are on site.
The leak has been stabilized and the site is under control.
The Kinosis wells have been suspended.
There were no injuries due to this incident. The environment, and the safety of our employees and contractors, remain priorities.
We are deeply concerned this incident has occurred. We are committed to identifying and correcting the cause, to minimize all impacts on the environment, and to clean up the spill site.
Representatives from the Alberta Energy Regulator (AER) were notified on July 15 and have been on site. Nexen continues to work with the AER throughout our response to this incident.
The size of the spill is estimated to be 5,000 m
of emulsion, over an area of approximately 21,900 m
mostly within a compacted pipeline corridor.
There is a small lake approximately 100 metres from the site. We have collected samples of the water to assess the water quality and that has been sent for testing. We expect to have those results in the next couple of days. There has been no visible contamination of this water body.
There are no homes in the vicinity of the leak site. We have proactively notified area stakeholders.
