What is Long Lake Heavy crude?
Long Lake Heavy is a heavy sour synbit composed of SAGD produced bitumen and synthetic crude upgraded from the same bitumen production. As such, PSH is a high TAN (2.03 mgKOH/g) though the MCRT is low (7.15 mg/kg) for a 20 API gravity Canadian heavy crude. PSH is produced only at the Nexen/Opti Long Lake Upgrader facility, and is transported to Hardisty for distribution on mainline pipelines.
