Harmonized, cross-border seismic velocity model for the Dutch, German and Danish North Sea area (Project 3DGEO-EU)
Within the GeoEra research project "3D Geomodeling for Europe” (3DGEO-EU, 2018-2021), a harmonized cross-border seismic velocity model for time-depth conversion was developed, covering main parts of the Danish, German, and northern Dutch North Sea. The model was created through collaboration between the Netherlands Organization for Applied Scientific Research (TNO, NL), the Geological Survey of Denmark and Greenland (GEUS, DK) and the Federal Institute for Geosciences and Natural Resources (BGR, GER). The transnational velocity model combines a V0-K layer-cake velocity model for Cenozoic and Mesozoic units with a Vint-DeltaT velocity model used for the Zechstein interval. In total, seven main stratigraphic layers were selected by the project partners to build the velocity model. As input data, velocity information gathered from 724 wells was used. For the Entenschnabel region covering the northwestern part of the German North Sea sector and adjacent areas in Denmark and the Netherlands, the original layer-cake velocity model compiled in Petrel (Doornenbal et al., 2021) was converted into two seismic velocity volumes with average velocities using Paradigm SeisEarth (Thöle et al., 2021). One volume was computed with salt structures modeled as vertical shapes, consistent with the original Petrel model, while the other was modeled without salt structures down to the base of the Triassic to correct for velocity pull-down effects beneath salt dome overhangs. For details on the creation of the transnational velocity model and the seismic velocity volumes, the reader is referred to Doornenbal et al. (2021), Thöle et al. (2021) and Bense et al. (2022).
