In several regions of the world, there are real prospects for
significantly higher production volumes of heavy crude. By its very nature,
heavy crude is much more difficult for refiners to process than the lighter
grades that comprise the bulk of the world’s crude production. Accordingly,
issues arise concerning the capability of the refiners in these regions to
process the higher production volumes of heavy crude.
The presentation will introduce the topic by briefly
characterizing the key differences, from a refiner’s perspective, of heavy
crude from its lighter competitors. Next, the crucial refinery processing
issues concerning heavy crude will be discussed. These issues include managing
the higher sulfur, nitrogen, and metals content of heavy crudes
as well as other concerns that frequently apply when processing heavy crude. In
addition, the implications for the refiner of processing heavy crude on their
desired refined product slate will be examined. Finally, observations will be
offered regarding the potential to integrate upstream and downstream heavy oil
projects to optimize capital and operating cost across the total value chain.
