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 for electric/electromagnetic heating of the reservoir, and a pressurization device for injecting a liquid into the reservoir in liquid form. A preparation entity extracts the liquid that is to be injected from a reservoir liquid that is taken from the reservoir or from a medium that is taken from the reservoir.
