ABSTRACT:
A method and apparatus for testing and calibrating an electromagnetic logging tool are described. The tool includes a tansmitting antenna and a receiving antenna. A shielded receiving device is placed around the transmitting antenna and intercepts the transmitted signal. A shielded transmitting device is positioned around the tool's receiving antenna and transmits to the receiving antenna a signal which has a phase and/or an amplitude related to the signal transmitted by the tool's transmitting antenna in a known manner which simulates the effects that a geological formation would have on the signal if it were to travel from the tool's transmitting antenna to the tool's receiving antenna through the formation. Since the simulated effect is known, the output of the tool may be verified as being correct or corrected if erroneous.
