Graphical representation of the drilling history and drilling-related pressure indicators of the Geretsried GEN-1 well. a Pressure in equivalent mud weight (EMW) in g/cm3 vs. true vertical depth (TVD) with drilling mud weight MW (brown line), hydrostatic pressure Hyd (blue dotted line), influx events (red dots and annotations), other overpressure indications (purple annotations) and stratigraphic tops. b Total gas readings while drilling on a logarithmic scale in percent (red lines and dots) and casing shoe points (black triangles). c Simplified lithological profile based on cutting descriptions from the geological well report (legend on the bottom provides key for lithotypes)
