A multidisciplinary study of a natural example of a CO2 geological reservoir in central Italy

The shallow boreholes at The AltotiBerina near fault Observatory (TABOO; northern Apennines of Italy)

“…Civitello; 5.6 km depth) that is one of the deepest wells drilled by the Italian National organisation for Hydrocarbons (ENI). Borehole and laboratory P wave velocities (Trippetta et al, 2010(Trippetta et al, , 2013 have been integrated with P wave velocities obtained from best migration analysis of the seismic reflection profiles (Mirabella et al, 2011) and earthquake data collected by TABOO (Latorre et al, 2014) to develop a detailed one-dimensional velocity model for earthquake locations (Table 1).…”

Chemical–mechanical coupling observed for depleted oil reservoirs subjected to long-term CO2-exposure – A case study of the Werkendam natural CO2 analogue field

“…Studies of natural CO 2 fields can aid in understanding long-term chemical-mechanical behaviour and improve the confidence in the mechanical stability of caprocks and reservoirs (e.g. see Major et al, 2014;Trippetta et al, 2013).…”

The high pCO2 Caprese Reservoir (Northern Apennines, Italy): Relationships between present- and paleo-fluid geochemistry and structural setting

“…However, this dating is to be referred to the secondary mineralogy assemblage, which is mainly consisting of quartz, Ca-Fe-Mg carbonates (calcite and ankerite), clay minerals (illite and chlorite series) and Fe-Ti oxides (Bicocchi et al, 2011). Consequently, PSS1 volcanic rocks probably date back to Permian-Triassic age (Trippetta et al, 2013).…”

“…and the altered volcanic rocks pertain to the Caprese Reservoir. Conversely, Trippetta et al (2010Trippetta et al ( , 2013 suggested that anhydrites of Burano Fm. efficiently seal pressurized fluids.…”

“…However, differences in the composition of coeval sectors of the reservoir cannot be excluded (e.g. Trippetta et al, 2013).…”
