Experimental Study of Stability and Integrity of Cement in Wellbores Used for CO2 Storage

Abstract

This paper examines the results obtained from lab experiments on cement deterioration in sulfate and CO2 environments. The experimental work consisted of preparing several sets of samples, placing them in environments at different conditions, and monitoring change in various properties once every two months for a period of one year. The parameters investigated were: Permeability Compressive strength Effect of diffusion using the scanning electronic microscope Shear and hydraulic bonding strength
