Pore pressure overview of the Geretsried GEN-1 well. a Pore pressure gradient estimate. TVD = true vertical depth; EMW = equivalent mud weight; PPvsp = pore pressure from vertical seismic profile (dark blue-dotted line); base case = pore pressure from base case 3D basin model (dark blue-dashed line); Hyd = hydrostatic/normal pressure (dashed light blue line); MW = drilling mud weight (brown line); kicks/influx = pore pressure estimates from influxes (red dots); σv = vertical stress (black line). b Total gas readings while drilling on a logarithmic scale in percent (red line and red dots) and casing points (black triangles). c Simplified lithological column
