INVESTIGATION OF POSSIBILITIES OF GALVANIC AND INDUCTION TEM-SOUNDING SYSTEMS FOR MAPPING 3D OBJECTS BY TEM
The paper presents the results of 3D modelling (program MODEM3D) of transient induction responses to cylindrical and conical objects for QQ-n and ABMN-n measurement system. Numerical modeling allows to give a positive opinion on the use of the electrical arrays for a specific geological situation. Analysis of relative deviations (with respect to the response of the reference medium) allows make qualitative estimates the depth and geometry of structures.
