Integrated Approach to Characterize Geothermal Reservoir Flow Potential: An Example From De Bilt-01

Identification and characterisation of dual permeability in potential geothermal reservoir rocks, by integrating image logs, acoustic waveforms, core data and well test results. A case study from the De Bilt-01 well, drilled in Utrecht as part of the SCAN data acquisition program initiated by TNO and EBN. The comprehensive well data sets acquired in this geothermal exploration wells includes cores, logging while drilling measurements, wireline logs, temperature data, as well as production-and-injection-tests. The integration of these various datasets provides crucial information about the reservoir quality and indicates their geothermal potential. in the well De Bilt-01, it was observed that the reservoir flow capacity is not only contributed by the permeable layers within Rotliegend formation but also enhanced by presence of permeable fractures and fracture zones.
