Abstract
A method of designing a cement blend for a wellbore isolation barrier based on the analysis of a stress state of the wellbore isolation barrier from the injection of COinto a porous formation. The analysis software may determine an optimized cement blend for a future COinjection schedule. The analysis software may determine a current near wellbore stress state for a current COinjection schedule. The analysis software may optimize a COinjection schedule based on the analysis of a future near wellbore stress state of the wellbore isolation barrier. The near wellbore stress state of the isolation barrier may be determined by at least one model accessed by the analysis software. The inputs into the model comprise periodic COinjection pressure and flowrate datasets, cement properties, and formation properties.
