Workshop Description

Various important phenomena in the subsurface are often governed by combined effects of fluid flow, mechanical, chemical and/or thermal processes. Examples are gas-production-induced earthquakes, reactive solute transport in aquifers, and safety issues surrounding the geological storage of energy, radioactive waste, and CO2. Although the sophistication of numerical models has increased significantly over the last decades, they typically focus on one or two of the aforementioned processes. This limits their ability to make predictions in many important applications. One approach would be to develop a new multi-disciplinary modeling framework, which can account for all essential processes. Another approach would be to couple existing codes which describe one or two processes in great detail. Both coupling approaches are complicated due to several physical and mathematical constraints and a number of important questions have to be investigated and resolved.

Themes

The issues described above will be the subject of this workshop. In particular, the focus will be on the following themes.

How to couple various processes? How much coupling is needed? Coupling of finite element and finite difference methods. How should different spatial discretization be linked together? Coupling models/processes with significantly different characteristic time scales (temporal discretization) Modelling coupled processes in density-dependent flow and transport, geomechanical processes, and biological systems
