Abstract
A method and arrangement are proposed for introducing a COcomposition into a subterranean geological formation for storage of COtherein. The COcomposition is initially injected into the formation using a first set of injection parameters at which the COcomposition is a supercritical fluid having first viscosity and density values. The injection parameters are then modified such that the COcomposition is injected into the formation using at least one second set of injection parameters at which the COcomposition 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 COcomposition.
