Geomechanical Modelling of Compressive Stress and Overpressures in Inverted Basins

O-30 GEOMECHANICAL MODELLING OF COMPRESSIVE STRESS AND OVERPRESSURES IN INVERTED BASINS Abstract 1 Until now there is a lack of knowledge on quantified compressive tectonic stress and the impact on the development of overpressures. In this study geomechanical modelling of basin inversion was done to asses the feasability of the modelling tool DIANA for improved quantitative insight in the magnitude of horizontal stresses in a compressive regime in relation to basin geometry and the role of pore fluids. Subsequently the impact of these compressive stresses on overpressure within the sediments was quantified. Introduction H.J SIMMELINK B. ORLIC and J.D. VAN
