Abstract

The Geological Survey of the Netherlands aims at building a 3D geological property model of the upper 30 meters of the Dutch subsurface. The model schematises the subsurface in millions of grid cells each measuring 100 by 100 meters in the horizontal directions and 0.5 meters in the vertical direction. Each grid cell of the model includes estimates of stratigraphy, lithofacies and lithology (clay, sand, peat) and if applicable, sand-grain size class data. Stochastic interpolation techniques are used to compute probabilities for these parameters, providing a quantification of model uncertainty. The model provides a sound framework for subsurface related questions on, amongst others, groundwater management, land subsidence, natural resources and infrastructural issues.
