Abstract
A method for the 'in situ' extraction of bitumen or very heavy oil is provided. An electric/electromagnetic heater to reduce the viscosity of bitumen or very heavy oil with at least two linearly expanded conductors are configured in a horizontal alignment at a predetermined depth of the reservoir. The conductors are connected to each other in an electrically conducting manner inside or outside of the reservoir, and together form a conductor loop, and are connected to an external alternating current generator outside of the reservoir for electric power. The heating of the reservoir is predetermined in a chronologically and/or locally variable manner in accordance with the electric parameters, and may be changed outside of the reservoir for optimizing the feed volume during the conveying of the bitumen. At least one generator is present in the related device, wherein the parameters thereof are variable for the electric power.
