The majority of the world’s known oil reserves contain oil that is too viscous (thick) or the oil reservoir lacks pressure to freely flow oil to the surface. In fact, conventional oil recovery methods are only able to extract about 10% to 30% of oil from a reservoir. The remaining oil requires additional manipulation in order to be extracted. These extraction techniques are generally referred to as enhanced oil recovery, or EOR. EOR allows oil producers to recover significantly more of the reservoir’s oil.
