Abstract

Overpressure is observed in many sedimentary basins worldwide, and knowledge of it is critical to the oil industry as it can<br>cause severe operational problems. The most commonly applied methods for quantifying pore pressure from downhole<br>logging data, drilling data, and seismic measurements rely on the compaction behavior of shales. These methods require the<br>determination of a so-called normal compaction trend line that represents the normal and expected decrease in porosity under<br>normal, hydrostatic conditions. Deviations from this trend are associated with overpressure. Typically, these normal<br>compaction trend lines are defined manually by an expert. However, with the increasing interest in automation for drilling and<br>also real-time wellbore stability modeling, the required manual input poses challenges for automation.
