Supports both Ridge Regression (least-squares) and Occam’s inversion for smooth model generation.
To appreciate the software, let’s walk through a typical project:
IX1D v3.50 is an all-in-one tool for 1D geophysical modeling, supporting a wide range of methods: DC Resistivity & IP : Supports standard arrays like Schlumberger Dipole-dipole Electromagnetics (EM)
A key study published at compared three approaches for interpreting Schlumberger sounding data: master curves, IX1D, and the IPI2win program. The analysis showed that: interpex ix1d v350
For decades, geophysicists and hydrogeologists have relied on Vertical Electrical Sounding (VES) to map subsurface resistivity. The technique—rooted in the Schlumberger or Wenner arrays—produces raw data that is almost useless without robust inversion modeling. Enter , a name synonymous with reliable geophysical software, and their flagship product, IX1D .

is a professional geophysical software application specialized in 1D inversion and interpretation of resistivity, induced polarization (IP), magnetotelluric (MT), and electromagnetic (EM) sounding data. Developed by Interpex Limited , it is a widely used tool in environmental, geotechnical, and groundwater exploration. Core Capabilities Workflow: How to Use IX1D v3
IX1D v3.50 is a 1D interpretation program that supports a wide range of geoelectric array configurations. It performs smooth modeling (Occam's inversion) as well as layered (equivalence) modeling.
IX1D allows users to choose between two main inversion philosophies:
: A tool that shows multiple "possible" underground models that could all fit the same data, helping scientists understand the uncertainty in their findings. Common Applications By providing a transparent
Before performing inversion, the user can run a using any user‑specified 1‑D resistivity model. This capability is valuable for survey planning—for example, to determine the required AB/2 spacings for a VES survey or the appropriate listening times for a TDEM sounding.
v350 allows you to fix layer thicknesses or resistivities, add smoothness constraints, and use “Occam’s inversion” for smoother models—critical when geology suggests gradational contacts rather than sharp boundaries.
IX1D includes specialized modules for interpreting electromagnetic variations:
Interpex IX1D v3.50 bridges the gap between raw field measurements and actionable geological insights. By providing a transparent, interactive environment for 1D inversion, it ensures that geophysicists can produce accurate subsurface models with confidence.
