Pore Pressure Prediction
More than 25% of drilling’s
non-productive time is due
to overpressure. In addition
to decreasing the NPT, correct
prediction of the pressure
regime in a well enables faster
drilling, less formation invasion
and therefore improved
production.
Our service offers:
Prospect pore pressure and fracture gradient prediction
Integrated engineering, well log, seismic and geological
interpretation
Seal analysis including centroid effects
Pore pressure volumes
High resolution velocity picking

When all available data is used correctly overpressure can be predicted
