In ore-targeted works bipolar VECS areal signal (measured dBz/dt component) is well described by the influence of a local conductor. Even a simple three-dimensional representation of the field signal provides a close to real, apparent electromagnetic image of the object. Calculation of 3D inversions al-lows more accurate localization of object boundaries.
Another thing is working for the oil and gas. Such surveys were held in Tatarstan, Kazakhstan, and California (USA). In all cases, obtained areal anomalies correspond well with other geological and geophysical data (seismic, geochemistry, drilling) contouring oil and gas. Using the powerful source al-lows one to register a signal from the deposit, as well as trace aureole changes caused by the migration of hydrocarbons from the reservoir to the surface. Aureole changes are very diverse, changed conductivity is not the most interesting and only usage of TM-polarization of geoelectromagnetic field, implemented in VECS method “makes use” of these factors. It became possible because the measured signal is free from the response of the enclosing environment.
