DescriptionLong Lake is an integrated SAGD and upgrader complex about 40 km southeast of Fort McMurray. The upgrader was idled in 2016 after a fatal explosion in January 2016; since then, the SAGD operation has sold diluted bitumen directly to market and the project functions as a SAGD-only producer. This file covers the complex; the ST53 scheme "Long Lake" tracks the SAGD bitumen line.
