A new technology has the potential to transform the transportation of tars sands oil. Right now, the already thick and slow-flowing oil, known as bitumen, has to be diluted with a super-light petroleum product, usually natural gas condensate, in order for it to flow through a pipeline or into a rail tank car.
However, scientists at the University of Calgary's Schulich School of Engineering inadvertently found a way to make tar sands oil even more viscous, turning it into "self-sealing pellets" that could potentially simplify its transport.
