47 1. Overview of the different geothermal systems: role of geophysics Furthermore, the geophysicist must communicate not only the results but also how various geophysical methods operate, the limitations of their usage, and the inherent measurement uncertainties and resolution limits. Clear and comprehensive communication of geophysical work results is paramount, especially for organizations seeking assurance in the design and planning of their projects. The value of geophysicists lies not only in obtaining the optimal geophysical model but also in their ability to integrate it effectively into the geological or geotechnical context. This process requires deep expertise to overcome challenges related to the interpretation of geophysical models and the communication of results and related uncertainties to engineers and project stakeholders. For industries, such as geothermal energy, where geophysical studies play an important role, the ability to articulate how the methods work, their applicability limits, and the uncertainties surrounding the results become critical. Figure 1.16 Selected list of geophysical techniques available to contribute to geothermal exploration and exploitation. By providing insights into the subsurface’s physical properties, geophysical methods help better understand, assess, and monitor geothermal resources. The goal is to enable engineers to optimize production, mitigate risks, and ensure the sustainability of the reservoir. Here is a selected list of the key information that geophysicists can contribute. • Identifying Subsurface Structures: It is important to assess the subsurface structure for geothermal energy production. For instance, faults, fractures, and geological boundaries between different geological formations are important to characterize. By understanding the geometry and distribution of these structures, engineers can identify areas where geothermal reservoirs are likely located.
