Abstract
In the last decade, the repercussions of global warming in Iraq have become more severe., scientists proposed storing carbon dioxide as it is the most greenhouse gas resulting from fossil fuel burning. As a result of the repercussions of injection operations, problems emerged related to the failure of the reservoir ‘s seal. The study created a model and applied a Simulation of the process of injecting carbon dioxide gas into the reservoir for a specific period. the computer modeling program (CMG) was carried out to study the distortions occurring as a result of increasing the hydrostatic pressure of the pore fluids on the seal. The study proved the results of secondary porosity due to the fracture of the rock structure two years after the injection process at a rate of 200 thousand cubic meters per day into the reservoir. The Barton Bandel model was used to diagnose permeability, as it was proven that the geometric deformation in the rock structure of the seal is proportional to the permeability resulting from the failure of the seal.
