O-37 MODELLING OF OVERPRESSURE GENERATION AND ITS IMPLICATIONS FOR HYDROCARBON MIGRATION AND LEAKAGE Abstract High resolution secondary migration modelling of oil and gas in the Northern North Sea has been performed along upper Jurassic carriers. The modelling has been performed both on a regional and on a block-specific scale and provides prediction of hydrocarbon phases within the mapped prospects at reservoir level. 1 An important aspect of the simulations is pressure compartment modelling. In this work we demonstrate how pressure modelling predicts high overpressures to be generated locally by diagenetic processes within isolated fault compartments. Further we show how the
