Palynology of core samples from Jurassic-Cretaceous intervals of six wells from the West Netherlands and Broad Fourteens basins, The Netherlands
report
In this report the results of palynological analyses on cored intervals from wells Gouda-01 (GOU-01), Hazerswoude-01 (HZW-01), Oisterwijk-01 (OIW-01), Delft-02 (DEL-02), Berkel-02 (BRK-02), K15-01 and P15-07. Wells K15-01 and P15-07 are from the Broad Fourteens Basin, all others are from the West Netherlands Basin, see Figure 1 and 2. The palynological analyses are carried out as part of the DeVli project, which aims to
stratigraphically constrain the Upper Jurassic and Lower Cretaceous deposits of the Broad Fourteens and West Netherlands basins. The project deliverables will consist of thickness maps and cross sections, which will be achieved by seismic mapping of six horizons which will be integrated with stratigraphic analyses of most wells occurring in the study area. The DeVli project is a joint collaboration of TNO Geological Survey of the Netherlands and EBN. The project is fully sponsored by EBN. The results of DeVli will serve as input for the
GEODE project (GEODE Atlas). Note that the original plan for palynological analyses within the DeVli project was to study the cored sections and side-wall cores of the Delft Sandstone and Rodenrijs Claystone members of the newly drilled geothermal wells DEL-GT-01 and DEL-GT-02. Initially, it was not possible to gain access to this material so an alternative plan was conceived with samples from small cored intervals of old wells, the results of which are reported in this document. The core samples were collected in May 2024 by Roel Verreussel (TNO). The samples were subsequently processed by Nico Janssen (TNO) and analysed and interpreted by Roel
Verreussel.
