Figure 1. Location maps of northwest Europe (inset) and North Sea with outline of the Permian Basin (gray shade, from Stemmerik et al., 2000), main structural elements, license blocks, and position of the three-dimensional (3-D) volume (study area, red square) and two-dimensional regional seismic profile shown in Figure 2. The study area is located in the Dutch sector and within blocks (A, B). It lies at the western flank of the Dutch central graben (DCG) and on the Step graben (SG) (A). Depth structural map of the top chalk (see also Figure 2) with main structural elements at top Permian (see Figure 2), salt diapirs, and position of the well sites, seismic line, and maps. Two main fault systems dominate the sub-Zechstein rocks (see Figure 2), westward verging north–south striking normal faults and dextral east–west striking strike–slip faults. The Zechstein rocks produces diapiric structures observed here as circular diapirs and salt bars (B). CG = Central graben; MFB = Moray Firth Basin; MNSH = Mid North Sea high; NLD = The Netherlands; NOR = Norway; RFH = Ringkøbing Fyn high; UK = United Kingdom; VG = Viking graben.
