Abstract

Fractures in wellbore cement and at the cement-host rock interface are potential leakage pathways for long-term carbon sequestration sites. Portland cement exposed to carbon-dioxide-rich brine undergoes a series of diffusion-limited reactions that form distinctive reaction fronts adjacent to the cement surface. This paper outlines a joint experimental and numerical modeling effort investigating the formation of these reaction fronts and their impact on fracture transmissivity. Prepared by LLNL under Contract DE-AC52-07NA27344.
