3D GRADIENT RESISTIVITY INVERSION

This software package is available as a standalone license but also part of the EMIGMA Complete licenses. It allows for various geophysical survey configurations (dipole-dipole, pole-dipole, gradient, borehole, cross-hole, Schlumberger, Wenner) but as well, more experimental designs. It offers a full range of functionalities required for the successful interpretation of IP/Resistivity data.

Includes functionality for MMR and MMR in both time and frequency domain.

EMIGMA's tools for 3D geophysical modeling of both Resistivity and IP are exceptional. The solutions are stable for electrodes near or inside anomalies; they are fast and accurate and on the IP side include many of the physical effects unavailable in other applications. With EMIGMA, you can model the so-called EM effects, susceptibility effects, off-time or out-of-phase resistivity contrast effects and you can also obtain MIP/MMR solutions.
