Deep Shale Oil Extraction Integrated with Carbon Dioxide Sequestration

Abstract:

That injecting carbon dioxide into the shale layer below 500 m to extract the shale oil is a method of oil shale exploitation that integrating environmentally friendly energy production and greenhouse gases sequestration. It has been shown by ground test that it is thermodynamically possible to extract shale oil with supercritical carbon dioxide (SCD). However, the prospect of ground extraction is influenced by low extraction rate and difficulty to extract the large molecules. It is fairly feasible if extraction by injection in situ together with the addition of surfactant such as APG for it doesn’t involved with factory building and power consumption. Several questions about the research situation of shale oil extraction and the problems to be researched about shale oil extraction with SCD have been discussed in the paper.
