A response surface model to predict CO2 and brine leakage along cemented wellbores

- We develop an integrated method for estimating well leakage from CO2 sequestration.
- Monte Carlo methods are used to generate runs across uncertain parameters.
- A multiphase porous flow simulator is used to calculate CO2 and water leakage.
- A response surface is generated from the Monte Carlo results.
- The response surface is converted to a ROM and used in probabilistic risk analysis.
