29 Introduction obliged developers to adapt geophysical exploration methods, geophysical well logging strategies as well as technical well design for reaching geothermal targets. Chapters 5 to 10 illustrate the use of geophysical methods for geothermal exploration and monitoring, with the following topics: • ERT-IP for geothermal exploration and de-risking, • The use of passive seismic methods for geothermal exploration and monitoring, • Seismic inversion and characterization applied to geothermal energy, • Seismic anisotropy applied to geothermal prospection, • Feasibility of monitoring cold fronts of geothermal doublets using 4D active electromagnetic techniques – a field trial in the Dogger play in the Paris Basin, • Defining high enthalpy geothermal drilling target with multi-physics integrated exploration program. Mayotte’s Petite-Terre Island case study. This book serves as both a guide and a call to action. It highlights the value of geophysical methods in building a sustainable energy future and emphasizes the need for collaboration across disciplines and sectors. Geophysics is not just a tool; it is the bridge between the subsurface’s hidden secrets and the engineers striving to harness them. Together, by investing in and advancing geophysical science, we can overcome the challenges of geothermal energy and unlock its full potential.
