Target reservoirs are characterized by high oil viscosities and medium to high residual oil saturations, or by low oil viscosities from medium to low residual oil saturations. The applicable combination depends very strongly on reservoir characteristics and fluidum...

..., steam is often not applicable and methods are needed to extend thermal techniques to reservoirs containing viscous oils where current applicability is poor. This includes thinner reservoirs, those with lower oil saturation or lower ratios of net/gross pay, to deeper reservoirs and to reservoirs...
