Being able to date geological events such as the age of the Earth has been one of the most significant acheivments of science. This project is developing methods for directly measuring, from analysis of the oil, how long the oil and gas we find today in a specific reservoir has been there. Surprisingly this is not possible at the moment! Being able to date how long oil has been in a reservoir is very important in understanding the timescales of alteration of light oils to heavy oils and oil sands and also gives us a lot of information on how the oils enter the reservoir and how to find the best quality oils to produce in Canada's heavy oil reservoirs. This will help increase recovery and reduce CO2 emissions in Canada's heavy oil belt. Dating the time oil has been in a reservoir also allows us to assess how leaky the caprock of the reservoir is to oil and gas and thus allows us to assess how effective some reservoirs would be as sites for industrial carbon dioxide (CO2) storage in the subsurface (carbon dioxide sequestration). Such deep CO2 storage is an important part (1/3) of Canada's plans for mitigating its CO2 emissions and climate change and being able to tell how effective caprocks are is very important. The project will train several students and postdoctoral scientists, and will further demonstrate to the world the cutting edge, ambitious research at Canadian universities.

能够确定地球年龄等地质事件的年代一直是科学最重要的成就之一。该项目正在开发方法，通过对石油的分析，直接测量我们今天在特定油藏中发现的石油和天然气存在的时间。令人惊讶的是，目前这是不可能的！能够确定石油在油藏中存在了多长时间对于了解轻质油向重油和油砂转变的时间尺度非常重要，并且还为我们提供了有关石油如何进入油藏以及如何找到在加拿大重油油藏中生产的最佳质量石油的大量信息。这将有助于提高加拿大重油带的采收率并减少二氧化碳排放。 测定石油在油藏中的时间还可以让我们评估油藏盖层对石油和天然气的泄漏程度，从而使我们能够评估某些油藏作为地下工业二氧化碳 (CO2) 储存场所（二氧化碳封存）的有效性。这种深层二氧化碳封存是加拿大缓解二氧化碳排放和气候变化计划的重要组成部分（1/3），并且能够判断盖层的有效性非常重要。 该项目将培养数名学生和博士后科学家，并将进一步向世界展示加拿大大学最前沿、雄心勃勃的研究成果。
