and inverse problems in numerical interpretation of elec-

tromagnetic logs in realistic models of terrigenous reser-

voirs penetrated by vertical, inclined or horizontal wells.

There also have been developed algorithms for numerical

correction of borehole rugosities and probe eccentricity

effects. Effective algorithms for fast two-dimensional

modeling and inversion were developed. Joint two-di-

mensional inversion for relative amplitude and phase

characteristics measured in electromagnetic logging al-

lows to estimate electrical conductivity and dielectric

permittivity. Algorithms for modeling in inclined and

horizontal wells allow to investigate signal features when

approaching and crossing boundaries. High-performance

calculations on GPU allow to carry out numerical inter-

pretation of data in real time.
