SPE Technical Section

Geothermal Technical Section (GTTS)

Advancing geothermal energy by leveraging the technical synergies with the oil and gas industry—accelerating innovation, sharing best practices, and enabling sustainable, reliable heat and power solutions in diverse geological settings. We connect people, projects, and ideas that turn subsurface heat into practical solutions for power, heating, cooling, and industry.

GTTS is a global forum where engineers, geoscientists, policymakers, investors, students, and communities work together to de-risk projects, scale new concepts such as superhot rock and EGS, and build a truly integrated geothermal value chain.

Message from the Chair

A message from Dr. Steve Cheung, SPE Geothermal Technical Section Chairperson.

Dear members (current and potential),

I am honored to serve as this year’s SPE Geothermal Technical Section chair. Wish you all Happy Holidays and a prosperous and successful 2026!

For member, we value your membership and hope you are enjoying our monthly webinars, and quarterly award-deserving newsletters. This technical section serves as a platform for sharing ideas, promoting new technologies, and finding career growth within this expanding energy sector. Let us grow this community, cultivate geothermal technologies and encourage field applications. Please inform your colleagues and friends about us and encourage them to join. We also need and welcome ideas and volunteers. If you have suggestions of improvement, or you are interested to help, please email me at SteveIOR@yahoo.com.

For those of you who are interest to learn more about this community. First, it is free for all SPE member. You just need to log in, click https://connect.spe.org/technical-sections/tshome and select geothermal.

This technical section involves all SPE Technical Disciplines (Completions; Data Science and Engineering Analytics; Drilling; Health, Safety, Environment, and Sustainability; Asset Management; Production; Projects, Facilities, and Construction; and Reservoir). We also warmly welcome geoscientists. In short, we work with and help O&G professionals pivot or expand into geothermal by providing focused resources, community, and career pathways. Please join us.

Lastly, I want to specially thank Willow Liu, and our vice chair, Gabrijel Grubac for collaborating with her, to greatly improve our web-page. Thanks to both!

– Steve Cheung, Ph.D., Chairperson, SPE Geothermal Technical Section

About

Who we are, what we do, and how we create value for the geothermal community.

About GTTS

The SPE Geothermal Technical Section (GTTS) is a home for members who share a common interest in geothermal energy and its potential to transform electric power, heating, cooling, and direct-use applications around the world.

We focus on transferring technology and practices from the oil and gas industry to geothermal development—leveraging decades of drilling, completions, reservoir, and facilities experience to reduce risk, cost, and deployment time.

  • Provide a neutral, technically grounded forum for sharing case studies and lessons learned.
  • Showcase emerging concepts such as superhot rock, closed-loop systems, and hybrid geothermal–CCUS developments.
  • Connect regional efforts across the Americas, Europe, Africa, the Middle East, and Asia–Pacific.

Mission & Objectives

Our mission is to advance the development and deployment of geothermal energy by harnessing the experience, technology, and infrastructure of the oil and gas industry.

  • Collect, disseminate, and exchange technical knowledge related to geothermal and adjacent petroleum disciplines.
  • Grow careers and businesses through skills transfer as geothermal scales.
  • Collaborate with industry, academia, regulators, and partner organizations while promoting best practices in safety and environmental stewardship.
  • Support students and early-career professionals through scholarships, mentoring, and leadership opportunities.
