“…The second one could be slightly deeper and/or better connected to deep horizons, therefore subjected to enrichment of gas with a deeper signature (i.e., higher 3 He/ 4 He and δ 13 C CH4 ). We therefore suggest that in the Fiumicino area several pockets of pressurized gas, with different chemical and isotopic characteristics, exist at depth of a few tens of meters (Barberi et al, 2007;Sella et al, 2014), and may mix each other. The drilling of the CdM boreholes caused the gas blowout of one of these pockets, fed by a mixing between two different gases.…”

“…Cementation aims to restore continuity in the impervious cover above the layer containing the pressurized gas, so preventing gas emission to the surface. In the 2005 Fiumicino gas blowout this was made by injecting cement into the boreholes obtaining a perfect result (Barberi et al, 2007). In the CdM 2013 operation, the boreholes were instead re-drilled and cased, and only the cased space was filled with cement, without ascertaining that annulus space had been properly cemented.…”

“…Near the gas source, lower concentrations, however never below 1.0%, characterized the central hours of both days. The day-night variations in air CO 2 concentration reflect efficient gas dispersion during the day by more intense wind circulation and gas accumulation during the night due to low or null winds Barberi et al (2007). The chemical composition of offshore gas is corrected for atmospheric contamination assuming that all O 2 except 0.1% (coherently with CdM measurements) is atmospheric.…”

On 24 August 2013 a sudden gas eruption from the ground occurred in the Tiber river delta, nearby Rome's international airport of Fiumicino. We assessed that this gas, analogous to other minor vents in the area, is dominantly composed of deep, partially mantle‐derived CO2, as in the geothermal gas of the surrounding Roman Comagmatic Province. Increased amounts of thermogenic CH4 are likely sourced from Meso‐Cenozoic petroleum systems, overlying the deep magmatic fluids. We hypothesize that the intersection of NE‐SW and N‐S fault systems, which at regional scale controls the location of the Roman volcanic edifices, favors gas uprising through the impermeable Pliocene and deltaic Holocene covers. Pressurized gas may temporarily be stored below these covers or within shallower sandy, permeable layers. The eruption, regardless the triggering cause—natural or man‐made, reveals the potential hazard of gas‐charged sediments in the delta, even at distances far from the volcanic edifices.

A primary concern for geologic carbon storage is the potential for leakage of stored carbon dioxide (CO 2 ) into the shallow subsurface where it could degrade the quality of groundwater and surface water. In order to predict and mitigate the potentially negative impacts of CO 2 leakage, it is important to understand the physical processes that CO 2 will undergo as it moves through naturally heterogeneous porous media formations. Previous studies have shown that heterogeneity can enhance the evolution of gas phase CO 2 in some cases, but the conditions under which this occurs have not yet been quantitatively defined, nor tested through laboratory experiments. This study quantitatively investigates the effects of geologic heterogeneity on the process of gas phase CO 2 evolution in shallow aquifers through an extensive set of experiments conducted in a column that was packed with layers of various test sands. Soil moisture sensors were utilized to observe the formation of gas phase near the porous media interfaces. Results indicate that the conditions under which heterogeneity controls gas phase evolution can be successfully predicted through analysis of simple parameters, including the dissolved CO 2 concentration in the flowing water, the distance between the heterogeneity and the leakage location, and some fundamental properties of the porous media. Results also show that interfaces where a less permeable material overlies a more permeable material affect gas phase evolution more significantly than interfaces with the opposite layering.
