The research project relates to unconventional oil extraction with a focus on new technologies to limit the use of water in the in-situ recovery of oil from heterogeneous oil sand reservoirs containing interbedded shales. Interbedded shales are large lateral clay-like intrusions interspersed within the oil sand reservoir that hinder the propagation of steam in SAGD (Steam Assisted Gravity Drainage), and hence oil production. Inducing the failure of shale by steam injection would require high pressures and considerable water usage because of low permeability of the material. Instead, the water within the shale is thermally excited by penetration of an electromagnetic (EM) wave just as when cooking food in a domestic microwave oven.

该研究项目涉及非常规石油开采，重点是限制在含有互层页岩的非均质油砂油藏就地开采石油时使用水的新技术。夹层页岩是分布在油砂储层中的大型横向粘土状侵入体，阻碍了蒸汽在SAGD(蒸汽辅助重力排水)中的传播，从而阻碍了石油生产。由于页岩材料的低渗透性，通过蒸汽注入导致页岩破裂需要高压和相当大的用水量。取而代之的是，页岩中的水通过电磁波的穿透而受到热刺激，就像在家用微波炉中烹饪食物一样。
