Periodic Reporting for period 1 - GeoHEAT (Georadar-aided High-resolution Exploration to Advance deep geoThermal energy usage)
Período documentado: 2024-06-01 hasta 2025-09-30
GeoHEAT will transform geothermal exploration through two key strategic shifts: (i) minimising pre-drilling exploration costs while quantifying and communicating the risks; and (ii) maximising learning rates of exploration drilling while reducing the costs of characterisation. As a first step, the high costs and shortsighted prospection are tackled with passive surface-based imaging methods and uncertainty encompassing modelling alternatives. In parallel to reducing measurement bias, our approach engages a larger population and stakeholder group in search for optimal locations for geothermal exploitation. In the following step, GeoHEAT illuminates the subsurface to an unprecedented extent through a novel georadar probe. The georadar imaging is complemented with drilling-induced microseismicity monitoring and digital rock physics models to create a high-resolution understanding of the reservoir. Our novel, multiscale approach unlocks the potential of informed deviated drilling, optimal wellbore placement and accurate performance and risk analysis. Throughout the GeoHEAT journey we propose effective and inclusive tools for public engagement and two-way communication while we introduce advanced decision-making tools for policymakers based on probabilistic modelling and uncertainty quantification. To maximize its impact and expediate its success, GeoHEAT consists of a complementary consortium with European leaders in the scientific, industrial, and public domain. The interdisciplinarity of our team allows us to look at geothermal energy exploration from different angles (e.g. geophysics, engineering, seismology, social sciences and humanities) and ensure the technical, scientific, economic and social sustainability of our proposed exploration workflow. By building on the results and expertise of previous and ongoing related projects, GeoHEAT contributes to the European-wide energy transition process to provide reliable, secure and competitive geothermal energy supply.
GeoHEAT has been advancing very smoothly from the onset. To date, 13 deliverables have been submitted on time and 25 are remaining. One milestone is reached however 2 were slightly delayed, because of personnel shortcomings. With an updated strategy we expect to reach those goal in the next few months. The tasks are defined per work package (WP) and the WP’s are closely linked to the objectives of GeoHEAT.
So far (first periodic reporting) we have collected a huge amount of data in the field and have updated our numerical tools and workflows. The development of the proposed georadar tool is well on track. We look forward to perform field studies with the already achieved methods and results.
