SENSITIVITY STUDY ON STORAGE OF CO2 IN SALINE AQUIFER FORMATION WITH FRACTURE USING REACTIVE TRANSPORT RESERVOIR SIMULATOR RCB
ABSTRACT
Storage of CO2 in aquifers is the only full scale proven method for storage of CO2. The initial structure of a given reservoir changes dynamically with injection of CO2 due to mineral reactions, changes in pore, and possible consequences on geomechanical stability. We present in this paper a new reactive transport simulator with implicit geomechanical analysis for aquifer storage of CO2, code RetrasoCodeBright (RCB). The original software package has been extended to a capacity of analyzing dynamically coupled flow, geochemical reactions and geomechanical reservoir stability as consequence of CO2 injection in a given formation. A 2D hydro-geochemical-geomechanical problem with a fracture is set up to illustrate the modified RCB code. A limited sensitivity study on this model has been used to show the impact of key variables on important geochemical and geomechanical features. Some future extensions of the code are also briefly discussed. Work on some of these extensions is already in progress
