Alberta oil sands systems guide

Solvent-assisted in situ recovery concepts

Some technologies add hydrocarbon solvents to reduce viscosity, improve recovery or reduce steam requirements.

Process role

Solvents can supplement or partially replace thermal energy in selected designs.

How the system fits together

Lower steam demand could reduce energy use and greenhouse-gas intensity if the system performs as intended.

Environmental and reclamation context

Solvent recovery, cost, reservoir behaviour and emissions determine whether that benefit is realized.

What to keep in mind

Different concepts are at different stages of deployment; pilot promise is not the same as sector-wide performance.

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.
