Alberta oil sands systems guide

Water use across oil sands extraction pathways

Mining and in situ extraction both use water, but source, intensity and recycling systems differ.

Process role

Mining uses water in ore conditioning and separation, while in situ uses treated water to generate steam.

How the system fits together

AER data show substantial recycling in both pathways, with particularly high recycling in in situ operations.

Environmental and reclamation context

AER also identifies oil sands mining as a high nonsaline-water user despite recycling.

What to keep in mind

Less water in one pathway does not automatically mean lower land or climate impact overall.

High-level industrial education only. Oil sands mines, thermal wells, extraction plants, upgraders and tailings facilities are hazardous regulated operations; this site does not provide operating setpoints, chemical recipes or equipment procedures.
