  • 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.

  • Patent number: 8875788
    Abstract: Electrical current flow is induced in a ferromagnetic conductor providing time-varying electrical current at a first frequency to an electrical conductor located in a formation. The ferromagnetic conductor at least partially surrounds and at least partially extends lengthwise around the electrical conductor. The ferromagnetic conductor resistively heats up to a first temperature of at most about 300° C. Water in the formation is vaporized with heat at the first temperature. Subsequently, time-varying electrical current at a second frequency is provided to the elongated electrical conductor to induce electrical current flow at the second frequency such that the ferromagnetic conductor resistively heats up to a second temperature above about 300° C. Heat transfers from the ferromagnetic conductor at the second temperature to at least a part of the formation to mobilize at least some hydrocarbons in the part of the formation.
