Zonal Isolation, Drilling and Exploitation of EGS projects (ZoDrEx)

The ZoDrEx project aims at demonstrating drilling, completion and production products and technologies that will increase the technical and economical chances of success in geothermal energy applications. By the end of the project, ZodrEx aims to demonstrate:

  • Fluid driven percussion drilling can be used in highly deviated trajectories to improve drilling efficiency in crystalline rocks, and that the impacts in percussion drilling can be dampened to a level compatible with downhole measurement systems, thus leading to substantial cost reduction in geothermal well construction.
  • Zonal isolation is key to efficient EGS stimulation and that zonal isolation technologies selection can be performed efficiently. Additionally, ZoDrEx will have contributed to the development of more robust zonal isolation technologies.
  • Operating EGS plants can be optimized through automation, protected against corrosion with more acceptable inhibitors, thoroughly monitored for ensuring the safety of the workers, the public and the environment.
