GRC Workshops

Please Note: Due to scheduling issues, the Renaissance Palm Springs Hotel room block is only available from 14-22 September. Those attending pre-meeting workshops and fieldtrips and needing a room 12 & 13 September at the GRC rate will have to make a reservation at the the Hilton Palm Springs Hotel where the room block is available 12-19 September. We apologize for the inconvenience.

Three GRC Workshops have been confirmed at the GRC Annual Meeting in Palm Springs, California, USA.

Friday & Saturday, September 13 and 14

Geothermal 101 - Open to the Public


New Frontiers in EGS Technology

Friday & Saturday, September 13 and 14

Room: TBD
Cost: $TBD (Member), $TBD (Non-Member), $TBD (Student)

Organized by: Sabodh K. Garg (Geologica Geothermal Group), Azadeh Riahi (Itasca Consulting Group), William M. Rickard (Geothermal Resource Group), and Will Pettitt (Geothermal Resource Council)

High-temperature geothermal resources are the manifestations of cooling magmatic intrusions, which are vertically zoned. Beneath the low-permeability cap and the hydrothermal circulation volume, there exists a zone of limited permeability where meteoric fluid does not circulate freely, and thus engineering intervention is required to enhance permeability and fluid circulation.

It is estimated that roughly 90% of the geothermal power resource reside in Enhanced Geothermal Systems (EGS). While realization of EGS development on the 100+ GWe scale would make EGS a significant component of the renewable energy portfolio, numerous technological challenges remain in accessing and characterizing, creating, monitoring, operating, and sustaining engineered reservoirs.

Development of cost-effective EGS technology is critical to the long-term viability of the world-wide geothermal industry. This workshop is the third in a series of EGS-focused workshops sponsored by the GRC (previously held in 2012 and 2016), focusing on the latest research findings and practical experiences in geothermal reservoirs. The workshop instructors are experts from geothermal and petroleum industry, academic institutions, and U.S. national laboratories. 

The workshop is composed of following four sessions:

  • Session 1-Experimental Studies: Advances in understanding of fracturing mechanisms and heat and mass transport at the laboratory (e.g. block experiments), intermediate (e.g. Collab), and field scale (FORGE) will be covered in this session.
  • Session 2- Reservoir Engineering: Common Practice and Technical Challenges: This session will overview engineering approaches to some of the EGS projects. Challenges associated with site characterization, stimulation, assessment of stimulated volume, and induced microseismicity will be discussed. Also, modeling of EGS processes at various scales, and novel numerical techniques such as discrete element modeling will be presented.
  • Session 3-Drilling: Issues unique to EGS (e.g. zonal isolation) will be discussed. Topics include: casing and wellbore design considerations for EGS wells, directional drilling in extremely hard rock, use of PDC bits and MSE, plus Stimulation, how do we do it and what is important from a completion point of view, zonal isolation and cementing considerations. 
  • Session 4-Panel Discussion: The concluding session will be a panel discussion on the technical and economic viability of EGS.

In addition to formal presentations, ample time will be allowed for questions/discussion between participants and workshop presenters. 

Space is limited; early enrollment is recommended.


Supercritical and Superhot Geothermal Resources

Saturday, September 14

Room: TBD               ?am - ?pm
Cost: $TBD (Member), $TBD (Non-Member), $TBD (Student)

Organized by Wilfred Elders (Professor Emeritus, UC Riverside)

There is increasing interest in supercritical and superhot geothermal systems as wells penetrating such reservoirs could potentially yield an order of magnitude more power than that currently produced from typical hot geothermal wells. Such resources are likely wherever young volcanic rocks occur at drillable depths.

The topics of the workshop will include:

  1. The enthalpy and flow characteristic of the supercritical state.
  2. Economic advantages for power generation and downstream use (including metal & mineral extraction).
  3. Environmental advantages.
  4. Examples of current projects in Iceland and Japan.
  5. The potential for magma power.
  6. Worldwide potential.
  7. Challenges of drilling and logging into corrosive fluids at high temperatures and fluid pressures.
  8. Cementing, casing, and well completion challenges
  9. Power production and fluid handling issues.
  10. Overview and prospects for the future.

Several subject matter experts on the above topics will be presenting at the workshop, and ample time will be provided for workshop participants and presenters to engage in discussion to explore select topics in more detail.

Space is limited; early enrollment is recommended.


Geothermal 101 - Open to the Public

Wednesday, September 18

Room: TBD         9:00-11:00am
Cost: Free to the general public and GRC Annual Meeting & Expo registrants


Presented by: TBD

  • 9:00 -10:00am - Visit the Expo to understand the practical applications of geothermal energy.
  • 10:00 -11:00am - Workshop in room TBD, explaining the basics of clean, dependable, renewable geothermal energy.
    Nevada legislators, energy regulators and their staff, educators, students and the general public are invited to a special workshop explaining the many benefits of geothermal energy.
Geothermal energy has been described as the most reliable renewable and a sustainable green energy. What does it take to discover and develop a high enthalpy resource? How does it fit into the mix of renewable electricity generation for the future?
