VELMOD-4 is the new version of the velocity model of the deep subsurface of the Netherlands. For the first time seismic stacking velocities have been used as input to the VELMOD velocity model in an effort to better capture the lateral velocity variation in between wells. The model integrates velocities measured in boreholes (sonic logs and check shot data) with the stacking velocities derived from seismic data. Check the VELMOD-4 page for more information and for links to download the report and model files.
VELMOD-4 available on NLOG
