DC/IP processing and inversion software


Res2DInv is a powerful 2D inversion software for ERT (DC) and IP data. The software offers a simple workflow from data import to inversion and visualization, while still offering full control over inversion parameters for advanced users.

The software is very flexible and can handle all conventional electrode configurations and custom 2D configurations, as well as underwater and cross-borehole surveys.

The software supports visualization of pseudo sections and inversions as well as export of the results for use with visualization and interpretation software.

Perpetual license options

  • Standard License: license can be unregistered manually within the software. Can be used offline for a limited time.

  • Floating license: license is automatically unregistered when SPIA is closed. Needs internet connection and can not be used offline. Optimal if Res2DInv is used on several PC's.

Key features​

  • 2D inversion of ERT DC and IP data for resistivity/conductivity and chargeability.

  • Supports all common electrode configurations as well as custom electrode configurations, underwater and cross-borehole surveys

  • Basic data processing options.

  • Supports smooth and sharp inversions.

  • Possibility to incorporate known geophysical information to guide and constrain inversion.

  • Easy visualization of pseudo sections and inversions as well as export of results to use in visualization and interpretation software.

  • Time-lapse inversion of data sets, and easy combination of separate data sets into time-lapse data sets.

  • Data import from a wide range of native file formats, including the standard .dat format.

More visualization in Workbench Essentials

Export results to Aarhus Workbench Essentials for more visualization such as:


  • Add profiles to GIS interface.

  • Create sections and add borehole information.

  • Grid inversion models and make depth slices (resistivity, conductivity etc.) on the GIS interface

  • Create PDF reports with results.

  • Create volumes by 3D gridding and add to 3D viewer.

  • Create fence diagrams in 3D viewer.
