Res2DInv and Res3DInv

2D and 3D resistivity and IP software for subsurface modelling

Build reliable subsurface models from resistivity and IP data dots

Res2DInv and Res3DInv help geoscientists quickly turn resistivity and induced polarisation (IP) survey data into reliable 2D and 3D subsurface models.

Built for near-surface investigations, the software supports a wide range of survey configurations—including boreholes, water bodies, and time-lapse monitoring—and delivers fast, reliable inversions using smooth, sharp, or constrained methods.

With a streamlined workflow and integration across the Seequent ecosystem, Res2DInv and Res3DInv make it easier to interpret complex geophysical data and share results with confidence.

Key benefits

Create reliable subsurface models from resistivity and IP data

Get fast, reliable inversion results

Run smooth, sharp, or constrained inversions using advanced algorithms designed for speed and reliability—even on large datasets.

Icon -Geological Modelling

Work with any survey setup

Support for topography, boreholes, water bodies, and streamed electrodes helps you model complex environments with confidence.

Icon -Modelling and Visualisation

Visualise and compare models with ease

Explore 2D sections and 3D volumes, compare multiple inversions side by side, and export to Workbench, Oasis montaj, or 3D visualisation tools.

Monitor change over time

Use time-lapse inversions to track subsurface changes in groundwater, permafrost, or geotechnical conditions.

Integrate with your geophysics workflow

Import data from a wide range of instruments and formats and export results to Seequent and third-party tools for interpretation and reporting.

Guide inversion outcomes with geological constraints

Apply smooth, sharp, or constrained inversion types to reflect expected subsurface structures and improve model interpretability.

Res2DInv

Res2DInv is designed for processing and interperting 2D electrical resistivity tomography (ERT) and induced polarisation (IP) data. It supports a wide range of survey configurations, including topography and boreholes, and provides tools for filtering, inversion, and visualisation. With live pseudosection updates and 2D time-lapse capabilities, Res2DInv is well suited for groundwater, environmental, and geotechnical investigations.

“We’ll spend a couple of days in the field running surveys, gathering the information, and putting the data into Res2DInv. This means that most of the time, we already know there is a water-bearing formation before we even start to drill. Or we know not to waste money drilling because there’s saltwater intrusion and it’s obvious in the results. It just works.”

Chris Hough, Global Fleet Manager - Living Water International
