METHODS FOR STORING CARBON DIOXIDE COMPOSITIONS IN SUBTERRANEAN GEOLOGICAL FORMATIONS AND AN APPARATUS FOR CARRYING OUT THE METHOD |
摘要 |
<p>A method and arrangement are proposed for introducing a CO2 composition into a subterranean geological formation for storage of CO2 therein. The CO2 composition is initially injected into the formation using a first set of injection parameters at which the CO2 composition is a supercritical fluid having first viscosity and density values. The injection parameters are then modified such that the CO2 composition is injected into the formation using at least one second set of injection parameters at which the CO2 composition is a supercritical fluid having second viscosity and density values that are different from said first viscosity and density values, wherein said injection parameters include the injection temperature, injection pressure and hydrocarbon content of the CO2 composition.</p> |
