An inversion framework for numerical modelling of pore collapse in soft porous rocks

Abstract

In this work we present an inversion framework to identify material properties defining the plastic behaviour of pore collapse modeled by thermo-hydro-mechanical simulations. This framework is built on the finite element REDBACK numerical simulator, which is capable of solving a multi-physics problem in a tightly coupled, massively parallel manner. We demonstrate the approach by matching the stress-strain response of an Adamswiller sandstone in a drained triaxial experiments.
