Stress variability around large structural features and its impact on permeability for coupled modelling simulations

Abstract

A clear understanding of rock stress and its effect on permeability is important in a coupled simulation where fluid production causes a significant increase in the effective stress within a reservoir. Changing the in-situ rock stress state can alter the reservoir properties. As a result, porosity and permeability could be affected due to the rearrangement of rock particles and the redistribution of sensitive pore structures.
