Possible reservoir formations include limestones, chalks and carbonate- cemented sandstones. To evaluate possible CO2 escape scenarios, and to model the long- term behavior of such reservoirs, data concerning the response of carbonate rocks to carbon dioxide introduction are needed.

Field geologic and structural mapping studies, in combination with the analysis of pumping tests and numerical simulations of flow and transport provide insight into the complexity of groundwater flow on

The main goal was to investigate whether reaction improves or degrades the sealing/healing capacity of fractured Type A cement plugs. Batch reaction experiments were performed for up to three

The experiments were conducted on pre-compacted calcite aggregates of various mean grain sizes in the range 1 to 250 μm, under dry and wet conditions, at temperatures of
