Abstract :
In this paper, the effects of the geometrical parameters of Electromagnetic Wave Resistivity (EWR) tool are studied. A model composed of three-layer formation, borehole, metallic mandrel, and coils, was built. The studied geometrical parameters include the cross-sectional shape of the antennas, transmitter-receiver spacing and receiver interval. Numerical analysis and simulations were employed to analyze the amplitude ratio and phase difference of the voltages measured between two receivers of the EWR tool.
