... of reservoir model's plume migration at strategic locations. Finally, leak detection tools such as an AUV with side scan sonar and a chemically degraded trigger and beacon could be used for leakage from the reservoir through the seabed and legacy wells respectively. This paper provides a novel integrated view...

... communication, both internally and externally, of the controls present for the most significant risks. The combination of bowties with a quantified, event tree-based model can allow for numerical determination of leakage probability and magnitude. Quantitative methods can therefore estimate insurance...

... the pressure drop across each reservoir in water injection subsea pipeline network. The data are collected from the gauges and are fed into the model with the incorporation of reservoir properties data. Monitoring of the possibility of leakages can be done by measuring the pressure of wells. A positive...

We measured laboratory geophysical data in the scenario of CO 2 flowing through a fracture in a sandstone core sample (De Geerdalen Formation, Svalbard, Norway) to see the possibility of detecting leakage. The field-scale feasibility was also demonstrated through a synthetic modeling...

... that the overall CO 2 leakage rates are very similar for the onshore and offshore scenarios, with subtle differences in flow rates of various phases likely arising from differences in pressure at the leakage point. Overall, the main differences between onshore and offshore CO 2 blowouts are expected to arise...
