Location: 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
Using Interpex IX1D v350, the geophysicist:
The client drilled two production wells based solely on IX1D v350 outputs. Cost savings compared to 2D ERT: ~70%. interpex ix1d v350
To appreciate the software, let’s walk through a typical project:
Older versions suffered from a dated, clunky interface. v350 features a cleaner layout, dockable windows, and improved graphics rendering. The resistivity pseudo-section display now supports real-time zooming and panning. Location: Alluvial basin in Rajasthan, India Goal: Locate
Interpex does not list public prices. Expect ~$800–1200 USD for a single-user license (perpetual). Maintenance (updates + support) is separate (~$200/year). A free demo is available (limited to 5 layers, no export). Competitors: Res1D (less common), IPI2Win (free, Russian, but buggy), ZondRes1D (~$400, modern UI).
To truly appreciate the software, one must understand its operational logic. The client drilled two production wells based solely
Interpex Ltd. (Golden, Colorado) officially sunset active development of the v3.x series after 2015, focusing on their cross-platform IX1D v4 and IX2D v4. However, the v350 version remains widely circulated in academic and government circles. Why? Because it runs offline, requires no license server, and has a predictable, deterministic behavior—critical for regulatory work where reproducibility is key.
As of 2025, new users can still obtain v350 through legacy software archives or existing license transfers. For training, the original .PDF manual (circa 2002) remains the definitive guide, often bundled with geophysics textbooks.
