"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
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.
