f Modelling of Three-Component EM Borehole Measurements to 3D Target

This paper summarizes results of the numerical modelling made for an EM borehole-system, in which both the magnetic dipole transmitter and three component receiver are in the same borehole (Lebedkin). Coil separation is fixed to values from 30 m to 120 m and the frequency range is from 20 Hz to 10000 Hz. Calculations were made by using MARCO software (Amira, Australia), which is based on volume integral equation formulation.
