... to ensure well integrity during the life of the well, providing competent annular pressure seal. Unlike conventional cement systems, self-healing system expands after setting, improving cement bonding and sealing micro annuli that can cause unwanted gas migration. Due to its improved mechanical properties...

... our comparative study of two cement systems that the stresses in the elastic cement are less than those in conventional cement. A parametric study has also been performed to analyze the effect of different cement properties. The results are quantified in terms of stresses experienced by cement sheath...
