Abstract
The viscosity of heavy oil may be incrementally reduced over what can be achieved by steam alone, by introducing an aqueous metal salt solution into a reservoir undergoing steam injection. The metal ion is selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo and Al. In a preferred feature CO is also introduced as a second additive, with a further oil viscosity reduction being observed with certain of the metal ions.
