Elemental mobility in carbon dioxide reservoir caprocks.
EMSL Project ID
47645
Abstract
Cap rocks for CO2 reservoirs are important to understand, as they must remain patent, or nearly so, to passage or leakage of CO2 and, if they leak, not represent a dangerous source of toxic metals that may contaminate aquifers above. Reactivity is a potential problem as metals leached into CO2 systems could potentially contaminate groundwater systems in the event of reservoir failure. We are studying the time-dependency of elemental concentrations in simulated CO2-brine systems in contact with potential cap rock compositions at elevated temperature and pressure. We need to look at the time and space dependency of elemental concentrations in the potential cap rock materials. Laser ablation ICP-MS has become the standard way to determine in situ concentrations and concentration gradients in minor, trace (and major) elements.
