Interpex Ix1d V350 !link! Guide
Offers both Ridge Regression and Occam's inversion to generate smooth or layered models.
At its core, is a sophisticated software program designed for the processing, interpretation, and display of one-dimensional geophysical sounding data. It supports a wide array of methods, including:
A key study published at compared three approaches for interpreting Schlumberger sounding data: master curves, IX1D, and the IPI2win program. The analysis showed that:
They laid out long cables across the dusty ground, performing a . The instruments sent electrical currents into the earth, measuring how much the ground resisted that flow. To the naked eye, these measurements were just a chaotic jumble of numbers and "apparent resistivity" values. The Digital Interpreter

Import your field data table consisting of electrode spacings (AB/2) and measured apparent resistivity values. Step 2: Data Masking and Filtering
: Allows users to explore a range of models that fit the data equally well, helping to assess the non-uniqueness of the solution. Data Handling & Compatibility
Fig. 1: The typical workflow for interpreting VES data using Interpex IX1D v3.50.
The standout feature of Interpex IX1D v3.50 is its broad integration of geophysical exploration protocols into a single, unified interface. The software supports the following methodologies: Offers both Ridge Regression and Occam's inversion to
To appreciate the software, let’s walk through a typical project:
This software is widely used in:
The software supports major electrode configurations used in Vertical Electrical Sounding (VES): and Wenner arrays Dipole-dipole , Pole-dipole , and Pole-pole configurations Input metrics include electrode spacings ( MNcap M cap N ) and measured apparent resistivity ( 2. Induced Polarization (IP)
The software supports Vertical Electrical Sounding (VES) data interpretation. It accommodates a wide range of traditional electrode configurations used to map subsurface resistivity layers. Supported arrays include: Wenner Dipole-Dipole Pole-Dipole Pole-Pole Induced Polarization (IP) The analysis showed that: They laid out long
The software's ability to model layers at shallow depths is critical for foundation design and environmental assessments. At the Talasea geothermal field in Papua New Guinea, geophysicists used the Interpex IX1D program to perform a 1D inversion of Schlumberger resistivity data. The results successfully modeled vertical variations in subsurface resistivity down to a depth of 200 meters, helping to detect geoelectric layers associated with geothermal activity. In other environmental work, engineers in Nigeria used IX1D to investigate the interaction between soak-away pits and hand-dug wells, processing data to determine the resistivity, depth, and thickness of subsurface layers to monitor potential pollution pathways.
Generates Occam-style smooth inversions (many thin layers with fixed thicknesses) to show continuous, realistic gradient transitions.
Geophysical inversions are inherently non-unique; different geological models can produce identical data curves. IX1D v3.50 addresses this by offering equivalence analysis. It calculates the allowable variance in layer thickness and resistivity, visually plotting the boundaries within which the model remains mathematically valid. 4. High-Quality Graphical Output
Interpex has hinted at releasing a 64-bit version to handle larger datasets and integrate with GIS workflows. However, the v350 build is stable, and the company focuses on bug fixes rather than feature creep. For users needing 2D inversion, Interpex offers ; for TEM data, IX1D-TEM . The v350 designation will likely remain current for several years.
