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已探明石油储量。不幸的是，这些储量主要由油砂组成，提取和精炼成本非常高。重油开采导致的二氧化碳排放量平均比轻质油高出三倍。因此，以环保和可持续的方式对这些重油进行商业开采需要制定合适的二氧化碳封存策略，以减少向大气中排放的温室气体。然而，除非我们能够可靠地检测到储层内的流体迁移，最重要的是检测到任何二氧化碳泄漏的存在，否则公众和政治上不太可能接受二氧化碳封存。
