A 2D seismic AVO inversion and well log analysis was performed to characterise a geothermal reservoir in the northern Zealand of Denmark in 2019. This case study shows how from the seismic inversion results it is possible to interpret different lithologies and estimate porosities through links established with well logs. The results revealed several layers of porous and clean sandstone as potential high-quality reservoirs for geothermal energy development within the Lower Jurassic unit and the Gassum formation. Even though the limited data available for the study caused some challenges, the obtained predictions seem generally reasonable when compared to existing regional well data, seismic interpretations and geological expectations. Ultimately, this study demonstrates the applicability of seismic AVO inversion for reservoir characterisation as a tool for de-risking geothermal resources.
