Introduction: The Evolution of Geoelectrical Modeling 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 Interpex , a name synonymous with reliable geophysical software, and their flagship product, IX1D .
Verdict: remains the most trusted name globally, especially for hydrogeological and engineering projects requiring defensible interpretations. Future Outlook: Will There Be a v360 or v400? 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 IX2D ; for TEM data, IX1D-TEM . The v350 designation will likely remain current for several years. Conclusion: Is Interpex IX1D v350 Right for You? If you perform routine VES surveys for groundwater, engineering, or mineral exploration, IX1D v350 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. “The best resistivity inversion software is the one you trust without second-guessing. For three decades, that trust has been placed in Interpex — and v350 proves why.” Ready to upgrade or purchase? Visit interpex.com to download a trial of IX1D v350 or request a demo license.

The release of represents a significant milestone. While earlier versions laid the groundwork for automated interpretation, v350 refines the user experience, updates inversion algorithms, and bridges the gap between field data and actionable geological models. If you still rely on legacy software or manual curve-matching, it is time to understand why IX1D v350 is the industry benchmark for 1D resistivity inversion. What is Interpex IX1D v350? At its core, IX1D v350 is a Windows-based interactive program designed for the processing, forward modeling, and inversion of DC resistivity sounding data. Unlike generic math packages, IX1D is purpose-built for geoelectrics. The "v350" designation indicates the version 3.50 release, which includes critical patches, UI enhancements, and compatibility fixes for modern operating systems (Windows 10 and 11).
