"Reliability of numerical models for simulating CO2 storage in deep geological formations"

The need to manage the global carbon cycle for mitigating the greenhouse effect has raised world-wide activities on developing concepts to store carbon dioxide in deep geological formations. Numerical models are hereby indispensible tools to assess upcoming questions concerning technical and economical feasibility, risks, and sustainability of CO2 storage. Since the relevant physical processes are very complex, it is of great importance to gain confidence in numerical modeling results. Due to the lack of data such models are very difficult to validate.
Therefore, we developed a strategy to improve the reliability of mathematical and numerical models by means of a series of problem-oriented benchmarks. This benchmark study addresses some specific problems of CO2 storage in different formations, for example, plume evolution, dissolution, non-isothermal effects, enhanced gas recovery, etc.
