Alberta oil sands systems guide

The water and steam cycle in in situ oil sands

Thermal recovery depends on a loop that treats make-up and produced water, generates steam and recovers produced fluids.

Process role

Steam condenses underground and much of that water returns to surface with bitumen and formation water.

How the system fits together

Produced water is separated and treated for reuse, reducing new water demand.

Environmental and reclamation context

AER reports high recycling in in situ operations, which is real progress; steam generation still consumes substantial energy and produces residual streams.

What to keep in mind

Water performance should be considered with emissions and energy intensity, not in isolation.
