Device and method for obtaining, especially in situ, a carbonaceous substance from an underground deposit

An apparatus for extracting a substance containing hydrocarbons from a reservoir, wherein the reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance, the apparatus comprising:

• at least one conductor loop for inductively applying current as an electric/electromagnetic heater,
• wherein a conductor of the conductor loop is surrounded in at least one section by a liquid-carrying conduit, and that the liquid-carrying conduit is perforated such that when a liquid is supplied the liquid penetrates into the reservoir from the liquid-carrying conduit via a perforation.

A method for extracting a substance containing hydrocarbons from a reservoir, wherein the reservoir is subjected to thermal energy in order to reduce the viscosity of the substance, the method comprising:

• providing at least one conductor loop for inductively applying current as an electric/electromagnetic heater,
• arranging the conductor loop such that a conductor of the conductor loop is surrounded in at least one section by a liquid-carrying conduit through which a liquid is carried, the liquid-carrying conduit being perforated,
• conveying the liquid through a perforation of the perforated liquid-carrying conduit.
