Abstract

Geological carbon storage will require that less than ~0.01% of the mass of CO2 stored escapes per year if significant climatic impacts are to be avoided (Hepple and Benson 2005). This requires that the geological storage sites retain much of the CO2 for more than 10,000 years. Predicting the security of CO2 in storage sites for such time periods raises questions which relate to a number of poorly understood fundamental processes concerning fluid-rock interactions in the near subsurface of the Earth. Because many of these processes are sluggish it is not possible to predict their significance from observations on active injection experiments with durations of, at most, a few tens of years. Nor do these experiments yet sample the full spectrum of potential behavior of CO2 in storage sites. For these reasons it is useful to study sites where natural CO2 has been retained in geological strata for periods which range from tens of thousands to millions of years.
