[1] 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.

[2] 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.

[4][5] In 2011, CNOOC Limited acquired OPTI, which included the 35% non-operated interest in the Long Lake project and joint venture lands.

[6] Enbridge Pipelines (Athabasca) Inc., a subsidiary of Enbridge Inc., (TSX:ENB) (NYSE:ENB) reported a pipeline leak site, about 70 kilometres southeast of Fort McMurray, near its Cheetham terminal on June 22, 2013, of approximately 750 barrels of Light Synthetic Crude oil from CNOOC's Long Lake upgrader SAGD project that spilled into a wetland area near Anzac.

[8] On July 15, 2015, a pipeline oil spill at the facility was discovered by a worker in the afternoon[9] which the factory's failsafe system was unable to detect.

[18][19] Investigations concluded that the subsurface pipeline ruptured in the muskeg due to improper design on June 15, but remained undetected by detection systems for a month until being discovered by workers.

[24] The Long Lake upgrader used OPTI's OrCrude process, which refines by-products of the extracted bitumen into usable fuel, which is used to generate steam.

[26] Enbridge's 540-kilometre Athabasca (Line 19) from Cheecham to Hardisty, a major part of the network that serves Alberta's oil sands, "can carry up to 570,000 barrels per day of crude from the Athabasca and Cold Lake regions to Hardisty, Alta., a major pipeline hub in eastern Alberta, about 200 kilometres southeast of Edmonton.
