We have developed new software for the numerical inversion of galvanic and induction measurements. Developed software is based on finite-element algorithms for 2D and 3D signals simulating and numerical analytical algorithms for electromagnetic signals transformations. Parallel computations on CPU and GPU are used to speed up the solution of direct problems in complex medium models. We use the BKZ (unfocused lateral logging tool with gradient arrays) and VEMKZ (high-frequency electromagnetic sounding tool) signals to estimate the electrical anisotropy and dielectric constant of impermeable high resistivity deposits. Using developed algorithms we performed the interpretation of practical data measured with SKL logging equipment on the Bazhenov Formation intervals in the central regions of Western Siberia. The electrophysical parameters of the Bazhenov Formation and stratigraphically identical deposits are studied, the material composition is determined, the main lithological types are identified. The results of the numerical inversion are consistent with laboratory measurements.
