This project is designed to integrate geological structural characterisation of fault zones with numerical modelling of flow behaviour at different scales. We will develop a 3D flow simulator which can model the impact of geological heterogeneities (clustered fault / fracture arrays) under different stress conditions on fluid flow. The project is collaboration between a structural geology research group (the rock deformation research group), an applied mathematics group (the centre for computational fluid dynamics) and a series of industrial partners (Arco, BP, Shell and Midland Valley).
