Free trial Well Logging Software Downloads

15 days free trial license: Apply to download (for non-commercial use)

This lightweight license has some the features of our commercial licenses. You can save all your work as GeolOil formatted GLOGTM files. Functionality to export built plots and LAS files to external software is restricted in this minimalist license. Furthermore, plot outputs have water-marks. It is ideal for users who want to quickly explore and evaluate the LAS GeolOil modules.

To apply for free trial license, the user must belong to a company or organization that satisfies two conditions:

  • The company or organization must have a Web Site.
  • Your email must match the URL company web site. It can not be generic. (like gmail, yahoo, hotmail, msn, etc.) Please don't insist.

Then send us an email with the following items to (make sure you white-list emails coming from to receive our answer):

  1. Your full name and position.
  2. Company name and country.
  3. Web site URL.

In our sole discretion, your application does not guarantee that we will grant you a free trial license.

One time only, 31 days license (for non-commercial use)

This one time only trial license is fully featured, and supports all the functionalities to export built plots and LAS files to external software. There are no water-marks in the produced plots. It is ideal for users exploring in detail the LAS GeolOil modules, or do some short term non-commercial work. Any user can acquire this one time only license. Afterwards, the user could buy a regular license, as this license is not renewable.

Only $ 99

When you click on the "Buy Now" button below, you will be redirected to the safe and secure PayPal payment gateway. Your installation is 100% guaranteed or your is money back. After payment you will immediately receive instructions to install and run your license.

Regular licenses (valid for commercial use)

Regular licenses are fully featured and are the only ones allowed to be used in commercial projects. There are no restrictions in these licenses. They can be leased for periods of time, renewed or purchased as perennial licenses.


  • All GeolOil petrophysics software runs on Windows, MAC, and Linux. However, we only offer installation support for Windows. Just make sure you have official java-8 JDK 64 bits installed on your system (for instance, something like jdk-8u*-windows-x64.exe for a Windows 64 bits system).

  • Unless you buy a perennial license, all trial and lease licenses require an internet connection for authentication. Please be aware that tight internet firewalls could affect downloading, updating and authentication. All those restrictions disappear when you buy a standalone perennial license.

LAS Petrophysical modules:

  1. LAS File Editor
    This module allows to fully edit LAS files: curve values, mnemonic names, well and parameter sections, export curves, import curves, import core data, remove curves, add curves, reorder curve positions, overlay curves, generate TVD depth curves, generate TVD-SS depth curves, and more.

    The module also allows to re-sample LAS files to change to a higher or lower depth step resolution, and merge several LAS files with their curves into a single new consolidated LAS file with the desired resolution, start and stop depths. Our exclusive matrix cell style editor allows to enter or remove individual curve values at hand, and even shift curves and core data in depth to match log MD curves.

  2. Curves Displayer
    This module allows to plot LAS files, define the well stratigraphy, the well path through its directional survey file, the well surface location in Google Maps, and display the log curves and zones. It has capabilities to shade zones, handle transparency, and even to measure TVD distances between zones for non vertical wells. Its use is very intuitive and simple, yet powerful.

  3. Sequential Petrophysical Functions
    The Sequential Petrophysical Functions tab allows to compute log functions specifying a dependency order to update the model. Besides standard formulas for Vshale, Porosity, Water Saturation and more, the module adds curve transforms for kernel smoothing, interpolation, algebraic functions, curves merge and more.

  4. Log Upscaler
    This module allows to produce petrophysical summaries. You can compute and adjust petrophysical cutoffs, upscale porosity, water saturation, calculate Net-Pay, Net-Sand, formation water resistivity Rw and Cementation exponent "m" easily and more.
