The Society of Petroleum Engineers Board of Directors has approved the Geothermal Resources Management System, a new framework for classifying and reporting geothermal energy resources. The system, developed with Project InnerSpace, is scheduled for publication in November 2026.
Why it matters
This system seeks to accelerate geothermal development by establishing standardized reporting methods, bridging a gap between the energy sector and finance. It adapts established oil and gas financial standards to provide the clarity needed for geothermal projects to scale.
The framework establishes a standardized classification system by adapting existing oil and gas finance reporting protocols for the geothermal sector. These protocols replace current inconsistent reporting methods with a singular, industry-consensus standard for resource evaluation.
The players
Society of Petroleum Engineers
A global professional organization that develops technical standards and best practices for the oil, gas, and energy industries.
Project InnerSpace
An organization focused on accelerating the global adoption of geothermal energy through collaborative technical and financial research.
The details
The Geothermal Resources Management System functions by applying the rigorous accounting and classification methodologies of the petroleum industry to geothermal heat and power assets. This process involved an extensive technical drafting and consensus effort conducted by industry working groups under the guidance of Project InnerSpace and the Society of Petroleum Engineers. The framework provides a structured method for firms to report geothermal resources in a way that is compatible with current energy investment standards.
Timeline
March 2026: The geothermal system was first announced.
October 20, 2026: The Board of Directors officially approved the system.
November 2026: The system is scheduled for formal publication.
The Tech Race
The new system aligns geothermal reporting with the established Petroleum Resources Management System, which has long served as the gold standard for hydrocarbon valuation. By adopting this structure, the geothermal industry aims to compete more effectively for capital within the broader energy market.
Investors and developers will gain a standardized way to report and compare geothermal asset viability by November 2026. This common language for resource classification is expected to simplify project financing and asset valuation across the international energy sector.
The takeaway
This framework represents a significant step in aligning geothermal assets with traditional energy financial markets. Stakeholders should watch for the publication of the final document in November 2026 to understand the specific compliance requirements for future projects.
