This data publication contains the following unique geophysical logs, collected from the multi-purpose research borehole DAPGEO-02, between 228 and 428 meters depth:

  • Nuclear Magnetic Resonance (NMR)
  • Full Waveform Sonic (FWS)
  • P- and S-wave velocity from PS suspension logging

DAPGEO-02 borehole is part of the seismic monitoring network of the geothermal research project on TU Delft Campus ( Well logs in this dataset are complementary to the Initial Borehole Dataset (, and will become public two years after the end of the data collection date, alongside the corresponding scientific publication.  

Full description of the logs and their processing is in the DAPGEO-02 Drilling Report (
