Wellbore integrity at the Krechba Carbon Storage Site, In Salah, Algeria: 2. Reactive transport modeling of geochemical interactions near the cement – formation interface

1st September 2010

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper describes a reactive transport modeling approach to assess key geochemical reactions between wellbore cement, formation mineralogy, and injected supercritical CO2 at the Krechba natural gas field at In Salah, Algeria. The findings informed a reactive transport model which considered advective transport of CO2 along the wellbore-formation interface and diffusive transport of CO2 and brine constituents into juxtaposed wellbore cement.
