ZoDrEx
ZoDrEx aims at demonstrating drilling, completion and production technologies increasing technical and economic successes of geothermal projects. ZoDrEx will demonstrate that:
- Percussion drilling can perform at high deviation in crystalline rock, and lead to substantial cost reduction.
- Zonal isolation is key to EGS stimulation and efficient technology selection is possible. ZoDrEx will contribute to developing robust zonal isolation products.
- Through automation, better corrosion protection, and monitoring, EGS plant's operation can be optimized while ensuring the safety of the workers and environment. 10 partners from DK, F, DE, E and CH, including 5 industry leaders, 3 engineering organizations, and 2 academic research organisations are gathered within ZoDrEx to deliver the required low-risk engineering and innovative solutions to access deep geothermal resources.
