The Hunt for Superhot Geothermal

Learning objectives

Attendees will have an overview of the state of the art of exploration for super-hot geothermal resources.

Workshop Overview

Morning:   Overview of the results from the recent DEEPEN project, on derisking exploration for geothermal plays in magmatic environments.  Topics will include:

  • Review of conceptual models from superhot/supercritical geothermal systems
  • Geophysical data and methods for deeper hotter targets
  • New geochemical modeling, equations of state, and experimental data for reaction kinetics for water-rock interactions at supercritical conditions (for natural and injected fluids)
  • New THMC modeling incorporating above info into coupled chemical-mechanical processes under supercritical conditions (for both natural and injected fluids but with a focus on injected fluids)
  • Approaches to integration of diverse datasets for superhot targets, including play Fairway Analysis (PFA) for multiple plays in magmatic systems and multigeophysical inversion (MGI)

Afternoon: Panels on superhot targets.  Topics will include:

  • State of the art in different regions
  • Major barriers/challenges
  • Power production estimates and risk evaluation
  • Terminology standardization and discussion
