Abstract
A device and method of using the device enable the in-situ extraction of hydrocarbons from oil sands and other hydrocarbon resources. The preferred embodiment of the device includes at least two electrodes of tubular form wherein said electrodes are porous and capable of being inserted into the ground; a source of electrical current to apply to the electrodes; and a means for extracting the hydrocarbons from the tubular electrodes. In the preferred embodiment of the method of the invention, the electrodes are inserted into the oil deposit and connected to an electrical potential difference sufficient to drive an electric current between in-ground electrodes. Current is then flowed between the electrodes. The pressure gradient, resulting from heating the oil-bearing fluid, drives product into the tubular electrodes where it is removed.
