Abstract

This chapter describes the development of a compositional reservoir simulator capable of modeling multiphase transport of carbon dioxide (CO2) in brine aquifers. As an example, it considers the radial injection of supercritical CO2 in a brine aquifer, and results are provided that illustrate the evolution of a 2-phase fluid system in which the injected CO2 resides in a dense supercritical phase and also dissolves into the liquid phase. Salt precipitation into a solid phase is found to occur close to the injection well where the gas phase dominates. To determine the feasibility of deep aquifer sequestration it is necessary to have a numerical model that can accurately predict the fate of CO2 under the conditions of interest. Conditions that support the existence of supercritical CO2 should be present at depths greater than about 800 m where pressure and temperature would be above the critical point of CO2.
