Abstract
Electrical current is caused to flow between an electrode well located in an aquafer above viscous hydrocarbon-bearing formation and an electrode well located in an aquafer below the hydrocarbon-bearing formation. The electrical current thereby tends to spread out in a broad plate-like configuration from each electrode well. This increases the area of the hydrocarbon-bearing formation through which current is flowed, thereby extending the region which is heated by electrical dissapation. The nature of the aquafers and their location eases and resolves much of the adverse vaporization and pressure buildup that occurs in other systems. This also allows water to be readily injected to into or produced from the electrode wells to further control vaporization and pressure buildup without adversely affecting gravity drainage, other drive mechanisms or injection programs operating within the hydrocarbon-bearing formation. In addition, this enables the electrode wells to be used in a more continuous manner.
