Geothermal Webinars 2024. #8: Mapping Geothermal Gradients Using Indirect Measurements

Finding the Heat: Mapping Geothermal Gradients Using Indirect Measurements
This is the eighth webinar in our 2024 Geothermal Webinar Series.
High-quality maps of the geothermal gradient are essential when assessing the geothermal potential of a region. However, determining geothermal potential is a challenge when direct measurements of in situ temperature and thermal property information are sparse (e.g. Ireland) and require significant risk reduction to understand the heat resource, before they can be fully utilised. In addition, individual geophysical methods are sensitive to a range of parameters, not solely temperature.
This webinar will focus on new subsurface temperature models of Ireland with uncertainty as part of the De-risking Ireland’s Geothermal potential (DIG) project. This will be followed by the current and future work for the MOD3LTHERM project. MOD3LTHERM builds on DIG by introducing a lithological component to the inversion as well as melt, and will be tested both in Ireland and at Krafla, Iceland. The new workflows will be used as a resource to investigate geothermal regions worldwide.
