Interpex Ix1d V350 =link= 🔥 Ad-Free

Interpex IX1D v3.50 is a professional geophysical software application specialized in 1D inversion and interpretation of resistivity, induced polarization (IP), magnetotelluric (MT), and electromagnetic (EM) sounding data. Developed by Interpex Limited, it is a widely used tool in environmental, geotechnical, and groundwater exploration. Core Capabilities

The software supports a broad range of geophysical methods and array configurations:

DC Resistivity & IP: Supports standard arrays including Wenner, Schlumberger, Dipole-dipole, Pole-dipole, and Pole-pole.

Induced Polarization (IP): Processes measurements in PFE (Percent Frequency Effect), Chargeability (msec), or Phase (mrad).

Magnetotellurics (MT): Performs inversion for apparent resistivity and impedance phase.

Electromagnetics (EM): Supports Frequency-Domain EM (horizontal/vertical coplanar and vertical coaxial), EM Conductivity (e.g., Geonics EM-31, -34, -38), and Transient EM (TEM). interpex ix1d v350

Well Log Integration: Can import resistivity well logs from ASCII files and interactively reduce them to discrete layers for model fitting. Modeling & Inversion Features

Forward & Inverse Modeling: Users can perform forward modeling to compare synthetic curves with observed data or use inverse modeling to automatically improve the fit to a layered model.

Inversion Types: Supports Robust inversion (typically 1 to 10 layers) and Smooth inversion (Occam’s method, 10 to 100 layers).

Graphical Editing: Features an interactive interface for dragging model layers (thickness, depth, resistivity) to manually adjust fits.

Equivalence Analysis: Allows users to explore a range of models that fit the data equally well, helping to assess the non-uniqueness of the solution. Data Handling & Compatibility Interpex IX1D v3

Import/Export: Supports flat ASCII, Excel, and Universal Sounding Format (USF) files. Graphics can be exported as DXF, WMF, or CGM formats for reports.

System Requirements: Compatible with Windows XP through Windows 10/11.

Copy Protection: Requires a USB or parallel hardware key (dongle) for full functionality. Licensing & Support

Pricing: A standard license for DC, IP, MT, and Frequency EM is approximately $999.00. A license including TEM capabilities is approximately $3,499.00.

Demo Version: A downloadable version is available at the Interpex download page, which is fully functional when used with supplied demo data but restricted for custom datasets until registered. 1D-Inversion Software IX1D - Resistivity - Georeva The Workflow A typical workflow in Interpex IX1D v3

The Workflow

A typical workflow in Interpex IX1D v3.50 involves:

  1. Data Entry: Importing field data (Voltage, Current, Spacing, or Apparent Resistivity).
  2. Data Filtering: Removing bad data points or noise spikes that could skew the inversion.
  3. Initial Model Setup: The user guesses the number of layers (e.g., 3 layers: topsoil, clay, bedrock).
  4. Inversion: The software runs an iterative process to mathematically fit the observed data.
  5. Interpretation: The geophysicist reviews the "Goodness of Fit" (error percentage) and the resulting layer depths/resistivities to write a geological report.

3. Expanded Data Format Support

The software natively reads:

Step 5: Export

Results export as text, images (BMP/PNG), or directly to Interpex’s IX1Dv2 format for reporting.

1. Enhanced Inversion Engine

The core Levenberg-Marquardt algorithm has been tweaked for better convergence stability, especially with noisy field data. v350 introduces adaptive damping factors that reduce the risk of overfitting—a common problem with earlier 1D codes.
