Uncertainty modelling of pore pressure by using Monte-Carlo approach in the Hammerfest Basin, Barents Sea
The results of this study suggest that: 1) The present Hammerfest Basin is neither affected by large amount of overpressure, nor there is an ongoing leakage detected, 2) the present overpressure distribution in the basin can be modelled with low deviation 2) overpressure history expands from late Ju...
