Abstract

The present disclosure relates to a deposit heater for heating an area of ground. The teachings thereof may be embodied, in particular, in inductive heaters useful for an oil sand, oil shale, extra-heavy oil, or heavy oil deposit. Some embodiments may include a deposit heater comprising: a first AC generator; a second AC generator; and an electrical conductor loop arranged at least partially within the area of ground. The conductor loop may be coupled to both generators. The first generator provides a first alternating current to a first region of the conductor loop and the second AC generator provides a second alternating current to a second region of the conductor loop.
