Drilling report multi-purpose borehole Delftse Hout online

Beginning of 2022 the last part of the seismic monitoring stations for the geothermal well on campus has been installed. DAPGEO-02 consists of several boreholes equipped with fibre optic cables as well as geophones. It also includes a multi-purpose borehole with a depth of 499 m. From this borehole, 87 cores have been retrieved of which 18 from the Maassluis formation and 69 from Paleogene clays. In addition an extensive set of geophysical logging tools have been run. The drilling report is available online (https://doi.org/10.4121/21640148).

The initial borehole data set and the CT scan data can be found via doi.org/10.4121/20299644 and doi.org/10.4121/21528819.
