Abstract: An arrangement and method is provided for introducing heat into a geological formation (e.g., a deposit present in a geological formation) in order to recover a hydrocarbon-containing substance from the deposit, where at least one underground mine working has been mined in the geological formation and the mine working includes at least one shaft and/or at least one gallery. An electrical conductor is introduced at least partially in the geological formation. The conductor extends in a first conductor piece within the mine working. The conductor has at least one conductor section configured such that, during operation, an electromagnetic field acts by electromagnetic induction on the ground adjacent to the conductor section so as to bring about an increase in temperature, and thus a decrease in the viscosity of a substance present in the adjacent ground. A second conductor piece of the conductor is also arranged in a bore in the ground.

Abstract: The invention relates to an arrangement and a method for introducing heat into a geological formation, in particular into a deposit (12) present in a geological formation, in particular in order to recover a hydrocarbon-containing substance from the deposit (12), wherein at least one underground mine working (1, 2, 3, 4) has been mined in the geological formation, and the mine working (1, 2, 3, 4) comprises at least one shaft (1) and/or at least one gallery (2, 3, 4). An electrical conductor (7) is introduced at least partially in the geological formation. In this case, the conductor (7) extends in a first conductor piece (73) within the mine working (1, 2, 3, 4).
