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!



Data Import

  • Time Domain IP - Zonge, ELREC6, Scintrex formats or as an ASCII text format
  • Frequency Domain IP - Zonge or ASCII text format
  • Resistivity Data with Phase if available - Zonge, SYSCAL(standard crosshole ASCII format),
    Generic ASCII text file

Data Processing and Correction

  • 1D digital and spatial filters - Mean, Median, Gaussian and Sovitzky-Golay
  • Smoothing and Decimation
  • Data Corrector tool combining dynamic spreadsheets and a line plotter for data cleaning, missing data interpolation and simultaneous plotting of different data channels for fast cross-analysis
  • Survey merging

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.

  • Fast and accurate 3D simulations: model suite generation and batch mode
  • Unlimited prism, plate and polyhedra targets
  • Multiple body interactions
  • Modeling of topography effects
  • Frequency-domain and time-domain IP
  • Magnetic effects in IP/Resistivity data
  • Variations in resistivity and Cole-Cole parameters
