Soil gas analysis and helium fluxes to trace leak paths at UGS Diadema - Argentina. Preliminary report

Monitoring of Diadema UGS, which is located in a depleted natural gas field, was carried out with different tools, which allow for an adequate control of operating activities. Diadema's monitoring activities included several campaigns of gas isotopic analysis. The activities included a pilot te...
