IX1D allows users to choose between two main inversion philosophies:
: Supports Frequency-Domain EM (horizontal/vertical coplanar and vertical coaxial), EM Conductivity (e.g., Geonics EM-31, -34, -38), and Transient EM (TEM).
The software provides two distinct pathways for data inversion:
Imports borehole resistivity well logs from flat ASCII files. Users can interactively simplify complex logs into discrete geo-electric layers using straight-line segment fits. Data Management, Visualization, and UI Features

Alluvial basin in Rajasthan, India Goal: Locate a fresh water aquifer under 40 m of clayey sand Method: 10 VES soundings with AB/2 from 1.5 m to 300 m IX1D allows users to choose between two main
: Supports flat ASCII, Excel, and Universal Sounding Format (USF) files. Graphics can be exported as DXF, WMF, or CGM formats for reports.
If you perform routine VES surveys for groundwater, engineering, or mineral exploration, is not just a tool—it is a professional necessity. Its blend of robust inversion, user-friendly interface, and industry credibility is unmatched. While newer methods exist, the 1D VES method—powered by IX1D—continues to deliver reliable subsurface models at a fraction of the cost of advanced imaging.
Note: If you are looking for the very latest updates, the software lineage has evolved into newer versions and suites, but v3 remains iconic in the industry for its stability and focused toolset.
A key study published at compared three approaches for interpreting Schlumberger sounding data: master curves, IX1D, and the IPI2win program. The analysis showed that: Graphics can be exported as DXF, WMF, or
IX1D’s user interface is designed for clarity. It can display data and model curves on standard log-log or linear scales , complete with error bars and fit statistics , typically Root Mean Square (RMS) error. Results can be visualized as a table of model parameters or as a color-filled profile of subsurface resistivity along a survey line, turning data into report-ready graphics that can be exported as DXF, CGM, or WMF files.
Once the smooth model identifies the main geoelectric boundaries, switch to a layered model ().
is a specialized geophysical software used for 1D sounding inversion . It is primarily designed to help geoscientists process, interpret, and display subsurface data for various electrical and electromagnetic methods. Core Capabilities
