De-risking geothermal plays by seismic reservoir characterisation

A field case is demonstrated to show how 2D seismic AVO inversion together with well log analysis can aid de-risking of a geothermal play by reservoir characterization in the northern Zealand of Denmark. From the seismic inversion it is possible to interpret different lithologies and estimate porosities via links established at well logs. Several connected high porosity sands were predicted, and with an expected temperature of around 50C in the target zone this gives room for a potential good geothermal reservoir. With this specific field case it is demonstrated how seismic AVO inversion can be applied where geothermal reservoir characterisation is needed in order to obtain a better understanding of potential geothermal plays.
