A process for the extraction of bitumen and / or heavy oil from a subterranean formation, associated system and method of operation of this plant

In addition to the known SAGD method, the deposit has already been proposed, also electrically, in particular inductively heated. For this purpose a electrical infrastructure is necessary. According to the invention the energy for generating the steam and the electrical heating is generated on site, for which purpose a part of the produced bitumen and / or heavy oil in an industrial turbine (1, 11) followed, at the turbine (1, 11) coupled generator ( 2) is burned. The industrial turbine can be a gas turbine (1) or a steam turbine (11). In particular, the industrial turbine (1, 11) followed by generator (2), a waste heat boiler (16) is assigned which is used to generate the steam and thus realizes a boiler. By temporary storage of the produced bitumen and / or heavy oil is in a closed circuit can be realized, which operates independently of external power supply self-sufficient with about 20% of the produced bitumen and / or heavy oil to promote.
