Your Energy Business Doesn’t Have to

Be Stuck

It’s easy to feel anxious about what tomorrow holds when you don’t have the insights you need to move forward.

In a complex and changing world, Purvis Energy Advisors delivers the deep oil, gas, and energy expertise you need to make clear-sighted choices in business and in litigation.

Our Commitment for COP28

December 18, 2023

Purvis Energy Advisors began talking publicly about the needs and opportunities of the energy transition in 2019, and the trajectory of my conviction has continued as others were catching on.  Today, it is encouraging to see that most major reservoir engineering consultancies and many new ones are advertising services to support the transition presumably because clients are asking for them.

Meanwhile, I and others in our firm have continued to research and deepen our understanding of the issues – and the solutions – beyond the insights of a news feed. Now we are taking the next step to engage the transition.

PEA will no longer offer consulting services that significantly contribute to the increase in oil and gas supply. Specifically, we will not consult on exploration or development of new fields nor on re-development of existing fields unless those projects are owned and controlled by historically disadvantaged communities or countries. We will honor our commitments to existing clients with a one-year transition, performing our work to the very best of our ability and assisting them to find other consultants to perform that kind of work in the future.

Instead, PEA will focus our efforts on helping companies, NGOs, and policymakers to decarbonize and manage the decline and decommissioning of existing fields, to resolve litigated questions that do not result in new supply, and to advance new forms of energy from the subsurface.  For example, we will continue to offer our expertise in reserve analyses, acquisition and divestiture, and rehabilitation of existing production. We will continue to provide expert opinions in contested settings and continue to provide research and education that empowers oil companies for new lines of business.

In all of our analyses and consistent with our standards as a registered professional engineering firm, we will continue to uphold our commitment to excellence and independence in all of our work without regard to our personal commitments to change.

What is more, PEA will effective immediately minimize and offset all our scope 1 and 2 emissions. We will reduce travel, minimize emissions of travel, prefer low-emissions products in purchasing decisions, and purchase high-quality offsets for remaining emissions.

We do not prescribe the same stance for others, much less offer judgment to those with different perspectives and convictions.  Not all our advisors have made the same commitment as I have, but I have come to terms with – and now stake my career on – the conviction that opportunities exist for petroleum engineers in a world working simultaneously and vigorously toward

both greater energy and lower emissions.

We Help Energy Leaders Build Cleaner, More Profitable Businesses

With dwindling opportunities for exploration and production, public opposition, and the threat of declining demand, navigating today’s energy landscape can seem a monumental task. That’s why Purvis Energy Advisors provides companies with guidance to survive and thrive in the future of the energy industry.

Our team has worked on dozens of basins all over the world and possesses specialized knowledge of a wide variety of technical issues and reservoir dynamics. We’ve worked in shale fields for nearly 20 years, and we created the now-standard concept of geologically similar areas within shale plays.

After two years of study at one of the top universities in world, we have a deeper and richer understanding of the energy transition than can be formed from any number of memes or news stories. Some of our projects have even been showcased on the front page of the Wall Street Journal and discussed on the south lawn of the White House. Others went no further than the family’s bank account.

Whether you face challenges with existing oil and gas assets or the unfolding energy transition is holding your organization back, it’s time to make a change. Contact Purvis Energy Advisors now, and let’s work together to create a better future for your business, our industry, and the people our industry serves.

Meet the Team

Dwayne Purvis, P.E.

Founder & Principal Advisor

For over 27 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.

Read More

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 serves 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.

Why Leaders Trust

Purvis Energy Advisors

  • Quantitative - Our team relies on history, general principles, and prior work as a starting point (not an anchor) for new and independent thinking. We never accept conventional wisdom as the dispositive answer.

  • Unbiased - We follow the data with circumspect analysis and consideration. Purvis Energy Advisors has taken unpopular stands both privately and publicly.

  • Novel insights - We have consistently seen what others have not in oil fields, in commodity prices, and in the energy transition.

  • Deep oil expertise - Our team has spent decades working both conventional millidarcy fields and studying shale fields since the Barnett shale blossomed under its home base.

  • True expertise - Most “experts” on the energy transition from within oil and gas have no more education than their news feed and no more insight than headlines. We’ve spent years in dedicated, academic study and research on the issues.
