Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., The source material is neither oil nor tar but bitumen, but is most generally described as an example of ultraheavy oil.”.
