Coupled Poroelasticity Viscoelasticity Model

When drilling around salt structures the pore-pressure and stress fields are hugely disturbed in comparison with undisturbed values (regional stresses), and those anomalies are difficult to predict. Additionally, the locally distorted stress field owing to salt is impossible to predict by common geomechanical procedures, and more sophisticated models must be implemented to give insight to over-pressure generation and stress field anomalies.
