In July, AER reported that Long Lake leaked 5,000 cu m of emulsion—a mixture of bitumen, produced water, and sand (OGJ Online, July 17, 2015).
The 55 shut-in lines are for crude oil, natural gas, salt water, fresh water, and emulsion. AER said those lines will not return to service “until Nexen can demonstrate that the pipelines can be operated safely and within all requirements.”
Nexen said it received an amendment order from AER on Sept. 6. “As a result, Nexen is able to maintain approximately 75% of our Long Lake oil sands production and upgrader operations,” the company said.
