Existing seismic data onshore the Netherlands are mainly 2D, most pre-date 2000, and have limited resolution beyond 3 km depth. The project team faced several challenges. As a result, the approach entails 2D gravity and magnetic modelling constrained by seismic interpretation of the post-Permian section, which in turn has been tied to reprocessed velocity and density well log data, and additional information on Moho and intra-crustal discontinuity depth from recent studies. In a paper presented at the 80th EAGE Conference & Exhibition 2018 in Copenhagen, Van Heiningen explains that these formations are out of the reach of existing seismic and well data. They exploited several geophysical and geological datasets in one modelling environment to demonstrate that several kilometers of sediments have been deposited and preserved below the Upper Triassic in the Roer Valley Graben. A recent project conducted by Pieter Van Heiningen of Provenance Exploration Consultancy BV and his business partners Vincent van Hoegaerden (EnerGeophy Consultancy), Dr Tijmen Jan Moser (Moser Geophysical Services) and Dr Nuretdin Kaymakci (Provenance Exploration Consultancy BV) used an integrated approach.
