The Geothermal Technical Section is for members with a common interest in geothermal energy and its potential to transform generation of electric power and direct heating and cooling across the globe.   

Geothermal energy is the only “green” energy source that has the potential to provide grid baseload power at scale.  It is in many ways, the closest energy source in terms of required skills to the upstream oil and gas industry.  

Geothermal and the oil and gas industry have been learning from each other for decades and are currently well placed to transfer technology and practices that can accelerate the drilling and completion of geothermal wells, reduce costs and revolutionize reservoir monitoring practices.  

 This Technical Section seeks to:

  • Collect, disseminate, and exchange technical knowledge concerning geothermal energy, and demonstrate its proximity to more traditional oil and gas disciplines.
  • Introduce opportunities to grow careers and businesses by knowledge and skills transfer.
  • Establish collaboration across industry and promote industry best practices

The SPE GTTS will provide a platform of learning and collaboration for SPE members working in or interested in joining the geothermal industry.  The SPE GTTS is intended to accelerate the translation of technologies and ways of working across the two industries to reduce the risk and costs of geothermal projects including

  • Exploration and development drilling and completion of geothermal wells
  • Revolutionizing reservoir modelling, monitoring and forecasting practices
  • Addressing flow assurance, project planning, product delivery & operations management
  • Sharing digitalization best practices
  • Supporting related R&D activities
  • Optimizing costs and resources in a heat or power-based business model
  • Workovers, facility designs, and operations

Enhanced Geothermal Systems (EGS)

The approach in enhanced geothermal systems (EGS) is to create permeability between rocks and adding fluids that would allow them to be sufficiently heated in a sustainable system (and thereby artificially create hydrothermal ‘reservoirs’).
This allows one to derive geothermal heat from beneath the surface to be used on the surface. As one creates these reservoirs artificially, one often also calls them engineered geothermal systems. Sounds familiar? 

Advanced Geothermal Systems (AGS)

The concept of advanced geothermal systems (AGS) has been coined by various groups targeting an approach that would remove the resource risk in geothermal development, namely the need to find sufficient temperature, find sufficient fluids, or in the case of EGS create sufficient permeability.

AGS does so by extracting thermal energy utilising a closed-loop system. It achieves this by circulating a working fluid through a long wellbore that conducts heat from the rock surrounding the well. These closed-loop systems are built on wells drilled that connect with each other allowing a heat exchange-type set up beneath the surface – at deeper levels than traditional geo heat-exchange systems.

SPE Geohackathon aims at educating and disseminating knowledge to all the participants on how Data Science applications can support Geothermal Energy Developments and drive the Energy Transition.
