Jason Currie. PG., MS. CEO and President of Point Bar Energy LLC, Oklahoma City, OK. USA.∎

"I have been using GeolOil for over 5 years. It is a great tool for doing petrophysical analysis with the ability to do several complex work-flows in a sequential format that is easy to setup and runs very quickly. The log displays are very good and it is easy to edit, shift, manipulate, and manage log curves..." Read more. September 2019.

Brian Black. Owner and Geologist. Black Petroleum Resources, LLC. Utah, USA.∎

"GeolOil has been great so far. I was glad to have found a package that runs fine on MacOS. I haven't yet fully utilized a lot of the software's capabilities, but I have uploaded tons of LAS files from a prior petrophysical analysis. It is easy to learn the basics and display the data in a visually impactful way" Read more. June 2017.

Michael Putnam. Independent Geoscientist. Texas, USA.∎

"GeolOil hits home on major areas that I look for in good software: 1) Platform independence. I use GeolOil in both MacOS, Windows and Linux, and have no issues. 2) The graphical interface and user experience truly is elegant. It is very easy to navigate, has natural flow, and good typesetting. I felt comfortable in the package less than ten minutes from when I first installed. The "major" commercial packages don't even compare or come close to ease of use or graphic design... " Read more. March 2016.

Evan Patrick Egenolf. Assistant Research Scientist. University of Wyoming, Laramie, Wyoming, USA.∎

"GeolOil is a versatile and intuitive tool for characterizing and analyzing geologic data. I have used it to input large amounts of stratigraphic data, and the program easily defines markers, formations, zones, and multiple sub-zones..." Read more. October 2015.

Chris Peterson. Senior Geologist. Magellan Petroleum Corporation, Colorado, USA.∎

"We have been using GeolOil since 2011. This package captures key geological settings of the reservoir. We have imported its results into the simulators Eclipse, Tempest-More, and CMG-STARS with the highest quality. ..." Read more. February 2015.

Mahmood Ahmadi, PhD. Vice-President of MI3 Petroleum Engineering, Colorado, USA.∎

"I have been using the LAS Displayer module of GeolOil for some months now. It has added tremendous value to my daily work because it allows a quick and neat access to critical petrophysical data, so I can devote more time analyzing information and making decisions regarding the reservoir simulation models I’m building. ..."
