What is Premium Albian Synthetic crude?

Premium Albian Synthetic (PAS) is a light sweet synthetic crude produced from the Scotford Upgrader. The Scotford Upgrader is part of the Athabasca Oil Sands Project (AOSP), a joint venture between Shell Canada Energy (operator and 60% owner), Chevron Canada Limited (20%) and Marathon Oil Canada Corporation (20%). PAS is a bottomless blend of hydrotreated straight run streams (naphtha, distillate and gasoil), and fully hydrotreated streams produced from a residue hydroconversion process (LC-Fining).
