| Outline of Final Research Achievements |
As the Canada Oil Sands, heavy oil is produced by injecting the steam into a reservoir to reduce its viscosity. However, the idea of incorporating a chemical solvent has also been proposed. Although it is necessary to evaluate what kind of solvent is optimum, selecting the optimum one economically in a short time is challenging. To solve this problem, in our study, we examined the construction method of digital oil for heavy oil, which is a molecular model of crude oil. We established a way of creating a molecular model based on the NMR data. Our approach made it possible to evaluate chemical solvents using molecular dynamics without conducting chemical laboratory tests on crude oil.

| Academic Significance and Societal Importance of the Research Achievements |
重質油は現在世界で広く存在しており、炭化水素資源としての重要性はまだまだ高い。しかしながらその生産には、重質油の貯留層にスティームの圧入など経済的に高価な面もあり、その十分な利用には至っていない。本研究で確立されたデジタルオイルによる重質油のモデル化は、個々の油田の原油に対して、粘性を低減させるに必要な温度・圧力条件、さらに最適な化学溶剤の種類について示唆を与えるものであり、将来における重質油の広い利用の道を開いた。
