Randy Freeborn, P. Eng – Chief Research Engineer


Randy Freeborn has practiced petroleum engineering for more than four decades, specializing in reservoir engineering, exploitation, and the evaluation of oil and gas properties. He is a graduate from the University of Calgary (1973 BSc. Eng.), holds membership in APEGA, SPEE and SPE, and has authored numerous technical papers. The Alberta Court has affirmed him as an expert in the field of Petroleum Engineering.

Randy is a subject matter expert in decline curve analysis, the use and construction of type wells, and forecasting unconventional oil and gas. This expertise has been recognized by his peers through invitations to present at SPE workshops and providing guest lectures to graduate students at Texas A&M and the University of Houston.


Randy is the Chief Research Engineer at 3esi-Enersight. He maintains an understanding of current technology by attending all relevant conferences, workshops and forums, undertaking independent research, and collaborating with other subject matter experts. When he identifies technology that is appropriate for inclusion in Value Navigator, he then builds prototypes for the company’s developers.

A major part Randy’s role is to share his expertise with clients and the industry in general. This sharing takes the form of giving luncheon technical presentations, working with small groups to explore different workflows and offering advice on matters that exceed the expertise of our support staff.
