Atmospheric emissions of carbon dioxide may be reduced by capturing CO2 at the source and storing it in the deep subsurface. Potential storage locations include abandoned oil and gas fields. The fields represent a likely location because they have proved to hold petroleum fluids over a long tome. However, to remove the petroleum from the formations wells have been used. Although the wells are plugged with cement when they are abandoned they still represent possible pathways for the CO2 to use to get back to the atmosphere.
My research looks are the effect of carbonated brines on well cement and the interface between the well cement and the host formation.
I am also interested in the risk that human and environmental receptors may face if they are living in close proximity to a storage site.
