... of potential spill points such as intersecting faults, plugged and abandoned (P&A'd) wells as well as leakage up the CO 2 injection wellbore. Current offshore CO 2 detection and monitoring falls into two basic categories: geophysical methods and CO 2 testing methods at wells sites. Geophysical methods...

... 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...

... 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 pressure...

... happens when there are no wells in close proximity to potential spill points? CO 2 leakage could be missed. A new approach has been developed with passive geochemical sorbers which have been used onshore for reservoir seal evaluation and CO 2 monitoring for some time. This new approach involves...

... Injection of CO 2 into porous rocks deep in the subsurface intrinsically has a low risk of leakage for three reasons: (1) Although CO 2 is buoyant compared to brine, layered rocks limit vertical migration. Injection zones are chosen with at least one well-qualified confining system...

...-focused monitoring. 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...
