Long Lake (oil sands)
The Long Lake oil sands upgrader project is an in situ oil extraction project near Anzac, Alberta, 40 km (25 mi) southeast of Fort McMurray in the Athabasca oil sands region of Alberta.
The project is owned and operated by CNOOC Petroleum North America, formerly known as Nexen.
Long Lake is an integrated steam-assisted gravity drainage (SAGD) site which produced 41,000 barrels per day (6,500 m3/d) of bitumen in 2017. The project used proprietary OrCrude technology as well as hydrocracking and gasification to produce Premium Synthetic Crude (PSC) oil, with a production capacity of approximately 58,500 barrels per day (9,300 m3/d), however the upgrader was shut down following a 2016 explosion.
