Download IP/Resistivity demo database
(works with our EMIGMA Demo)
The Resistivity/IP software package is available as part of EMIGMA Premium or Professional Complete, as a standalone product or an add-on to other EMIGMA software licenses. It allows for various geophysical survey configurations (dipole-dipole, pole-dipole, gradient, borehole, cross-hole, Schlumberger, Wenner) and with 3D Inversion it offers a full range of functionalities required for the successful interpretation of IP/Resistivity data.
Includes functionality for MIP and MMR
Unlimited survey size!

3D Modeling
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, off-time or out-of-phase resistivity contrast effects and you can also obtain MIP solutions.
