Abstract

A device is provided for extracting a hydrocarbon-containing substance from a reservoir. Thermal energy can be applied to the reservoir in order to reduce the viscosity of the substance. The device includes at least one conductor loop for inductively supplying electric current, to provide electric and/or electromagnetic heating, and a fluid conducting device for transporting and introducing a solvent fluid into the reservoir, to further reduce the viscosity of the substance.
