| Abstract Scope |
In successful applications of carbon sequestration technologies, CO2 gas has been transported into underground reservoirs. Oil well cements have been widely used to seal the well for potential leakage of CO2 gas. However, CO2 may leak from the interface of different materials: the interface between steel casing and cement annulus, and the interface between the cement annulus and surrounding rock.
The first part of this work is to experimentally study the possibility of using nanoparticles for repairing the cracks and leaks generated in the well cement used in underground CO2 storage formations. Several types of nanoparticles can be injected into the distressed cement to repair wellbore leakage. The injection is done using a new electro-migration method. The second part of this work is to develop a numerical modeling for simulating the injection process of nanoparticles. A general framework for numerical modeling is developed to describe the proposed nanoparticle injection technology. |
