Interpex Ix1d V350 Jun 2026

At its heart, IX1D solves the geophysical inverse problem: given measured apparent resistivity values, find the true resistivity and thickness of subsurface layers. The software supports two distinct inversion workflows:

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. interpex ix1d v350

It interprets transient electromagnetic data, which is often used for deep sounding applications. At its heart, IX1D solves the geophysical inverse

The software shines in its interactive graphical environment. As the user adjusts model parameters—such as layer thickness and resistivity—the software instantaneously calculates and displays the resulting theoretical sounding curve. This "forward modeling" capability is invaluable for educational purposes and for building initial models. It also features equivalence analysis , a vital tool to understand non-uniqueness, where different geological models can produce nearly identical apparent resistivity curves. It interprets transient electromagnetic data, which is often

For massive sulfide bodies (extremely conductive) or oxide zones (resistive), 1D soundings over a grid can outline drill targets. v350’s dipole-dipole array option is particularly useful for profiling lateral resistivity changes.

stands as a mature, reliable, and versatile tool for 1‑D inversion of geoelectrical and electromagnetic sounding data. Its combination of multiple survey methods, robust and smooth inversion algorithms, well‑log reduction capability, and interactive graphical interface makes it an essential component of any near‑surface geophysicist’s software toolkit.
