Process role

Bitumen is a very heavy petroleum material that does not flow like conventional light crude under reservoir conditions.

How the system fits together

Alberta’s Athabasca, Cold Lake and Peace River areas contain the major deposits.

Environmental and reclamation context

Depth and geology determine whether development uses surface mining or in situ recovery, which also changes the dominant land, water and emissions impacts.

What to keep in mind

The resource is large, but recoverability, economics, environmental obligations and regulation determine what is actually developed.
