  • Patent number: 8881800
    Abstract: An installation for the in-situ extraction of a substance including hydrocarbons from an underground deposit is provided. The conductor and return conductor of the inductor lines are guided essentially vertically in the capping to the bottom of the deposit, at a small maximum lateral distance of 10 m compared to the length of the lines, but especially less than 5 m. Preferably, the inductor lines are guided horizontally in the deposit and are at different distances in certain areas. Furthermore, the electrical conductors and return conductors perpendicularly extending in the capping preferably combine to form a conductor pair. In this way, the conductor pair can be introduced into a single borehole which reaches into the reservoir and splits only once it has arrived in the reservoir.
