ABSTRACT: This paper summarises the results of a benchmark study that compares a number of mathematical and numerical models applied
to specific problems in the context of carbon dioxide (CO2) storage in geologic formations. The processes modelled comprise advective multi-phase flow, compositional effects due to
dissolution of CO2 into the ambient brine and non-isothermal effects due to temperature gradients and the Joule–Thompson effect. The problems
deal with leakage through a leaky well, methane recovery enhanced by CO2 injection and a reservoir-scale injection scenario into a heterogeneous formation. We give a description of the benchmark
problems then briefly introduce the participating codes and finally present and discuss the results of the benchmark study.
