Study area, basin model set-up and locations of used wells. a Study area and extent of 3D basin model with used wells and stratigraphic boundaries. The Geretsried GEN-1 drill site is marked with a gray star, the calibration wells A–D are marked with black crosses, while black dots indicate additional wells (B1–B15) used to constrain the 3D basin model. One well is outside of the map area and was used to constrain the extent of the Lattorf/Sannoisian. The map coincides with the extent of the full basin model, which has been reduced to an area of interest (AOI, marked by the black lined polygon) after simulation. According to the used well data, pinch-outs towards the north-western part of the study area have been incorporated into the 3D basin model for Upper Cretaceous (dashed–dotted line), Eocene (dashed line) and Lattorf/Sannoisian (dotted line). The red line marks a cross section represented in b. b NW–SE cross section through the basin model showing the individual layers, sublayers and incorporation of pinch-outs. Vertical scale in true vertical depth (TVD) in meters. The section is vertically exaggerated by a factor of 2
