: Version 3.50 supports a wide range of methods, including:
With , multiple soundings can be grouped into profiles . The software can interpolate 1‑D inversion results across a survey line to produce 2‑D resistivity cross‑sections, offering a semi‑2D view of subsurface variations.
Understanding how the software processes geophysical data requires looking at its dual-mode mathematical processing engine.
: Features an interactive interface for dragging model layers (thickness, depth, resistivity) to manually adjust fits. interpex ix1d v350

Understanding Interpex IX1D v3.50: A Comprehensive Guide to 1D Geophysical Sounding and Inversion
Future versions are expected to maintain the same intuitive interface while improving inversion speed, expanding data format compatibility, and possibly adding more advanced 2‑D interpolation techniques. The split into IX1Dv2.exe and IX1Dv3.exe executables indicates that Interpex plans to support multiple parallel update paths for different user needs. : Version 3
IX1D includes specialized modules for interpreting electromagnetic variations:
Beyond its mathematical core, the software’s practical utility is enhanced by several key features. The “forward modeling” mode is exceptional for educational purposes and hypothesis testing, allowing users to build synthetic geological models (e.g., a resistive layer over a conductive aquifer) and instantly view the resulting apparent resistivity curve. Critically, the V350 version introduced advanced capabilities like the handling of induced polarization (IP) effects, allowing for the joint interpretation of resistivity and chargeability data—a powerful combination for mineral exploration. The ability to import and export data in multiple formats, alongside a manual "picking" routine to estimate asymptotic resistivities, streamlines what would otherwise be tedious calculations.
Geophysicists can manually input or dynamically manipulate stratigraphic models through an integrated spreadsheet grid. Models can be structured via absolute layer depth or explicit layer thickness. Boundary elevations automatically calibrate themselves dynamically whenever surface topography data is supplied. Parameter Isolation via Fix Flags : Features an interactive interface for dragging model
The client drilled two production wells based solely on IX1D v350 outputs. Cost savings compared to 2D ERT: ~70%.
: Traditional arrays like Schlumberger and Wenner.
Interpex has continually refined IX1D. Key milestones include:
It is stable on older and modern Windows versions (XP through 10/11). Accessibility:
