Device for measurement and monitoring of resistivity in an oil reservoir in a geological formation, and.Process for measuring resistivity in an oil reservoir in a geological formation "the invention is a device for measuring and monitoring of resistivity in a reservoir of petru00f3leIn a geological formation with an injection well, observation or production, comprising a pipe shaft electrically conductive metal.With the unique and inventive being characterised by the following features: (a) a source of electric power; (b) at least one transmitter antenna induces to electromagnetic waves.Arranged in a fixed mode in the pit, out of the metal surface outer tube shaft; (c) at least one series of sensors comprising N sensors of resistance inducers (5a, 5b,..., 5N) arranged to receive the electromagnetic waves and the generation of measurement signals, arranged in fixed mode in the well.In the oil reservoir and out of the metal surface outer tube shaft; and (d) a driver signal to the measuring signals.
