Heavy oil/oilsands will be an important part of Canada's and the extended global supply. Almost one-third of the world's oil is in Canada in the form of heavy oil and bitumen or so called "oilsands". However, due to very high viscosities of these resources, conventional recovery techniques are not applicable. The current method of enhanced recovery or surface mining has significant environmental impacts such as tailings treatment, high water consumption, landscape alteration and inefficient land use. The sustainable technologies are in-situ oil sands recovery methods namely using heat-Steam Assisted Gravity Drainage (SAGD), using solvent-Vapor Extraction (VAPEX), and combination of the two (hybrid).

重油/油砂将成为加拿大和全球供应的重要组成部分。世界上近三分之一的石油以重油和沥青或所谓的“油砂”的形式存在于加拿大。然而，由于这些资源的非常高的粘度，常规的回收技术是不适用的。目前的强化回收或露天采矿方法对环境有重大影响，如尾矿处理、高耗水、景观改变和土地利用效率低下。可持续技术是原位油砂回收方法，即使用热蒸汽辅助重力泄油（SAGD），使用溶剂蒸汽萃取（VAPEX）以及两者的组合（混合）。
