Synthetic crude oil, sir, is the bitumen, and invariably they could add other types of product to it, such as a lighter oil, to reduce the viscosity so that it is able to flow through the pipeline. They could add a solvent; they could add a lighter oil; they could add any number of fluids to it that seek to reduce—because it's very tarry, very heavy in its composition—that viscosity by adding another product to it such that it can flow through the pipeline.
