CO2 sequestration in a depleted on-shore gas field in Italy: a feasibility study

Major aspects of cap-rock sealing efficiency, cement deterioration and reservoir injectivity in the frame of a CO2 storage pilot test in an on-shore depleted gas field in Italy have been addressed through laboratory and modelling studies. The objective of the effort was site qualification, and identification of the maximum reservoir pressure at which CO2 can be stored for thousands of years.
