... to CO 2 saturated brine up to one week. The measured elastic moduli show a decreasing trend versus time. This time-dependent modulus was implemented in a user-defined model built into FLAC3D. The features of this model were first tested with a simple geometry. Then wellbore geometry was introduced...
