Only 10 % of recoverable oil reserves in Alberta’s Oil Sands can be extracted through surface mining. The rest requires unconventional in-situ recovery techniques. Currently, only a few enhanced oil recovery techniques focus on developing unconventional resources such as heavy oil in an environmentally conscientious manner. One such technology that will be investigated in this report is Toe to Heel Air Injection (THAI). This new technology has been pioneered by Petrobank (Calgary based oil company) with immediate relevance in sustaining a greener and more cost-effective Oil Sands development. In this report a detailed process, environmental, economical, and social analysis will be performed on this innovative technology from a chemical engineering standpoint. The purpose of this report is to showcase the impact of using a green technology such as THAI by evaluating the various chemical and non-chemical prospects associated with the process. A case study of the application of THAI against other in-situ recovery process (ISR) such as Steam Assisted Gravity Drainage (SAGD) and steam flood tests will also be evaluated. In conclusion, a brief discussion of the limitations and future scope for innovation will will be presented. The demand for energy is greater than ever now, THAI is aimed at developing a cleaner, greener and economically viable Oil Sands resource by utilizing the core principles of green engineering. .
