Canada has the second largest proven oil reserves in the world. Unfortunately these reserves are predominantly composed of tar sands with very high extraction and refining costs. Heavy-oil exploitation leads also in average to three times larger CO2 emissions than lighter oils. Commercial exploitation of these heavy oils in an environmentally friendly and sustainable fashion therefore demands the development of suitable CO2 sequestration strategies in order to reduce the emission of greenhouse gases into the atmosphere. Yet public and political acceptance of CO2 sequestration is unlikely unless we are able to detect fluid migration inside the storage reservoir reliably and most importantly the presence of any CO2 leakage.

加拿大拥有世界第二大石油储量。不幸的是，这些储量主要由焦油砂组成，其提取和精炼成本很高。重油剥削的导线平均也是二氧化碳排放量的三倍，是较轻的油。因此，以环境友好和可持续的方式对这些重油进行商业开发需要开发合适的二氧化碳隔离策略，以减少温室气体的排放到大气中。然而，除非我们能够可靠地检测到存储储层内的流体迁移，否则公众对二氧化碳的隔离不太可能是不可能的，最重要的是，任何二氧化碳泄漏的存在。
