    The Using of Carbone capture and its storage is widely recognized as one of the three primary system for reducing carbon emissions, the storage of CO2 is the principal element. The economical assessments of this initiative is about the development and implement of the CCUS technology at a huge scale, focused to the CO2 storage. The aim as the selection of a suitable sites for a geological storage of the CO2, The monitoring of a dynamic process with this site and the reduction of the leakage. To achieve the goal, the type of study applied to the transient electromagnetic 3D finite-difference method and used Yee's grid subdivision.Firstly, the horizontal model and the deep saline aquifer inclined were developed to analyze the low resistivity response which is the characteristic of the same aquifer Secondly, the geoelectrical model which changed about time of the CO₂ injection that was made to examine the temporal variations in subsurface resistivity during the process of CO₂ injection and analyze the impact of different injection volumes. The meaning of these results stems from their potential contribution to the development of an efficient dynamic monitoring and boundary delineation strategies for CO2 geological storage. Last one is a geoelectrical model for leakage that has established to find out different changes in a resistivity of the subsurface strata as a result of CO2 leakage, as well as the transient electromagnetic response patterns along with the leakage paths. This contributes to the monitoring of CO2 leakage in real time as well as the location of leakage channels. From the simulation results, it can be concluded that theorically, the transient electromagnetic method has a potential to do a successful capture, the dynamic diffusion process of CO2 storage in a deep saline aquifers; furthermore, it could be used to an efficient monitor of CO2 leakage and identify the leakage paths.
