... the reactivity of wet supercritical CO 2 , at 150°F and 3000 psi on Portland cement plugs (class G), for exposure of up to 5 weeks. For nanoporous media, such as cement, diffusion is believed to be the major mass transport mechanism. To quantify the extent of the alteration (mineralization/dissolution) on fluid...

... with compaction and de-watering, we infer that bacterial sulphate reduction had a major impact during early diagenesis as it resulted in significant calcite cement precipitation. Calcite cements infill bioclasts and foraminifera chambers, thereby significantly reducing intra-granular porosity. Fine grained...
