Geophysics Software Utilities

Several free and downloadable Tools are listed below.

Electromagnetic Induction (EMI) Skin Depth and Depth of Investigation (DOI) calculator  EM Skin Depth and DOI Estimator (xlsx)  .  This application enables the calculation of the DOI below the ground surface when performing electromagnetic induction surveys.  The DOI calculator allows the input of parameters to approximate the depth of signal penetration to determine how deep an EMI investigation will image subsurface electromagnetic properties.

Archie's Law calculator Archies Law Estimator (xlsx)  . The Archie's Law calculator enables the user to estimate Archie parameters (e.g., fluid conductivity, formation factor, and porosity) when performing an electrical resistivity survey.

DTSGUI is a public-domain software tool to import, manage, parse/cull, georefence, analyze, and visualize fiber-optic distributed temperature sensor (FO-DTS) data.

These Utilities are for instructional and demonstrational purposes only.  EPA does not endorse their use or validate results generated from these calculators.  Use at your own risk.
