Abstract
An apparatus is provided for delivering a substance containing hydrocarbons from a reservoir. The reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance. The apparatus includes at least one conductor loop for inductively applying current as an electric/electromagnetic heater. A conductor of the conductor loop is surrounded in at least one section by a liquid-carrying conduit. 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.
