Bitumen, the heavy, viscous form of crude oil associated with Alberta’s oil sands, has been the workhorse behind Canada’s ascent to near the top of oil-producing nations. However, it is impossible to get raw, near-solid bitumen to refiners by pipeline without either upgrading it to a flowable crude oil or blending it with lighter hydrocarbon liquids, a.k.a. diluents, to form the more diluted version of the product, referred to as “dilbit.” As for moving bitumen by rail, there are two main options: using heated tank cars or blending it with diluent to form “railbit.” The rapid rise in bitumen production in the past decade — interrupted only by wildfires and the recent price crash — has generated a large parallel market for diluents, whose fortunes are closely tied to the oil sands. U.S.-sourced diluent currently meets a substantial portion of the demand. But with Alberta oil sands development poised for renewed growth and in-province condensate production rising, the Canadian diluent market could be in for some big shifts. Today, we start a blog series considering the unique role that this special form of hydrocarbon plays in the oil sands.
