... is relatively small and depends mainly on the frequency of operation and composition of a reservoir. Electromagnetic heating can be adjusted to accommodate any water saturation, especially for low water content ( Sresty et al., 1986 ). It has been suggested to heat a reservoir by applying microwaves at 2.45 GHz...

The hypothesis of this paper is that the unusual McMurray reservoir water saturations are a result of the geological history of the McMurray oil sands, during which the densities of hydrocarbon and formation water became similar in magnitude over geological time. This greatly weakened buoyant...

We further control the vertical distribution of these zones using a triangular periodic function that depends on layer depth and connate water saturation. Changing the period of the dominant function yields different kinds of lean zone distribution...
