However, its capability for the real CO2 sequestration case should be verified by the inversion approach with reasonable monitoring scenario. In this study, we developed a 2.5D mCSEM inversion algorithm and analyzed integrated sensitivity for successful inversion. Based on the result of sensitivity analysis, 2.5D inversion is applied to horizontal CO2 injection model with reasonable a priori information of the monitoring. In addition, we exploited modified secondary (MS) field method and sharp boundary constraint in inversion to enhance the resolution of our inverse problem.
