Dwayne Purvis, P.E.
Founder & Principal Advisor

For over 30 years, registered professional petroleum engineer Dwayne Purvis has answered the reservoir engineering and strategic questions faced by executives, owners, and litigants. He worked for a major reserves certification firm, pioneered analysis of shale reservoirs, served as the engineering manager for a private producer, and even operated a few wells.

In recent years, he has become a widely recognized trainer and a spokesperson for the oil industry’s need to engage in the energy transition. As a leader in the field, he personally experienced how overwhelming the change can be—and the risks we face if changes aren’t made. To face those risks, he recently completed a master's degree in sustainable energy from Johns Hopkins University.

Today, he helps oil and gas producers make the best engineering and strategic decisions they can with their legacy assets and to recognize and seize the opportunities of the energy transition.

Dwayne teaches, writes, and speaks on both technical and strategic topics across the industry. He often presents at society meetings, and his insights have frequently been featured in the Journal of Petroleum Technology and OilPrice.com. He also created and hosts one of the earliest decarbonization conferences for oil and gas, CarbonExpo.

He teaches industry courses for the American Association of Petroleum Landmen, SAGA Wisdom, and TRC Consultants, and he served as an adjunct professor at Texas Christian University’s Ralph Lowe Energy Institute. He is a member of the National Speakers Association, multiple oil industry organizations, and an active 25-year member of the Society of Petroleum Engineers.

He often presents at society meetings, and he served as a Distinguished Lecturer on end-of-life issues for the Society of Petroleum Engineers.  His insights have been featured in the Journal of Petroleum Technology, OilPrice.com, and numerous media outlets.
