Interpex Ix1d V350 Site
Interpex IX1D v3.50 represents a mature phase of geophysical processing software. It bridges the gap between old-school manual curve matching and modern high-speed computing. For geophysicists working with vertical soundings (VES) or specific EM conductivity meters, it remains a reliable and trusted utility for converting raw data into actionable geological insights.
Interpex IX1D v3.50 1-D sounding inversion program designed for geophysical data processing across several methods, including DC Resistivity, Induced Polarization (IP), Magnetotellurics (MT), and Electromagnetics (EM) Core Capabilities Supported Methods DC Resistivity
: Supports Wenner, Schlumberger, Dipole-dipole, Pole-dipole, and Pole-pole arrays. Induced Polarization (IP) : Handles PFE, Chargeability (msec), and Phase (mrad). Magnetotellurics (MT) : Inversion for apparent resistivity and impedance phase. Electromagnetics (EM)
: Supports Frequency-Domain (Horizontal/Vertical Coplanar, Vertical Coaxial) and Transient EM (TEM) configurations such as central, fixed, or coincident loops. Inversion Options : Offers both (1 to 10 layers) and (10 to 100 layers) inversion types. Forward Modeling
: Allows users to compare synthetic curves to observed data to calculate RMS errors. Google Groups Version 3.50 Specific Features Well Log Integration
: Capability to read resistivity well logs from flat ASCII files and interactively reduce them to discreet layers by fitting straight-line segments. Enhanced Modeling interpex ix1d v350
Forward modeling of TEM data using custom or standard waveforms (ramp-on/ramp-off).
MT forward modeling using plane wave or user-defined segmented wire sources. Interactive Editing
: Graphical editing of model parameters including thickness, depth, and resistivity directly on the display. Google Groups Data Management & System Info Import/Export Formats
: Supports ASCII, Excel, and Universal Sounding Format (USF) for imports. Graphics can be exported as DXF, CGM, or WMF files. Operating System
: Compatible with Windows XP through Windows 10 (both 32-bit and 64-bit). Protection : The software requires a USB key for copy protection. Google Groups Interpex IX1D v3

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.
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.” Interpex Ltd
