Practical process design for in situ gasification of bitumen

The province of Alberta, Canada hosts an estimated 170 billion barrels of crude bitumen reserves in the Athabasca, Cold Lake and Peace River deposits. These reserves are commercially recovered through surface mining or in situ recovery methods. Most of the produced bitumen is converted in surface up...

These reserves are commercially recovered through surface mining or in situ recovery methods.

In situ recovery or mining as well as bitumen upgrading and refining are energy intensive processes that generate huge volumes of acid gas, consume massive volumes of water, and are costly. Bitumen upgrading requires hydrogen, and currently most of it is produced by steam reforming of methane. Alternatively, hydrogen can be generated by in situ gasification of bitumen. In situ gasification of oil sands is potentially more energy efficient with reduced emission to atmosphere since acid gases are sequestered to some extent in the reservoir.
