Pore pressure overview and velocity data of the calibration wells. Depth in true vertical depth (TVD) from ground level, pressure and stress in equivalent mud weight (EMW) in g/cm3. ad also show casing shoe depths (black triangles), drilling mud weight MW (brown line), hydrostatic pressure Hyd (dashed light-blue line), estimated pore pressure from VSP or sonic data (PPseis, blue line), estimated pore pressure from the 3D basin model (C19 = dashed dark blue line, C21 = dotted dark blue line, Sch2 = dotted black line, LC3 = dotted brown line, Eo1 = dotted cyan line), vertical stress σv (solid black line), total gas readings TG (red annotations) and stratigraphic tops (black annotations). a Overview of Well A. Total gas data were not available. b Overview of Well B. The green dots represent drill stem test pressure data (DST). c Overview of Well C. d Overview of Well D. Pressure cavings are annotated in purple
