Abstract:
1. Measuring equipment for mapping the geology in an underground formation, comprising: at least one transmitter circuit with at least one transmitter coil and a current source, the transmitter coil including a wire and being located in a plane; at least one switch which is inserted between the current source and the at least one transmitter coil and which serves to connect the current source of the at least one transmitter circuit with the at least one transmitter coil during operation thereby generating an electrical current (I at least one receiving circuit with at least one receiving coil and being placed in an area where the induction in the receiving coil from the current in the transmitter coil is zero or minimal, wherein the at least one receiving coil is located in a plane that is tangential to a field line of the magnetic field, and the receiving coil is located in a plane that is parallel to the plane of the transmitter coil.
