clarity of monitoring results. Advanced tracer technology operates at low detection levels, as low as parts per trillion (PPT) or even PPQ. As demonstrated through application in K12 and In-Salah projects, tracers provide the ultimate proof of connection in the Interwell communication patterns (see Figure 2 ), significance, or quantification of magnitude of communication (see Figure 3 ), and coverage or sweep (storage) (see Figure 4 ) volume. Using tracers is not merely about confirming the presence or absence of a connection. Tracers enable the quantification of the magnitude of communication between different areas, allowing for a detailed analysis of storage volume. This approach provides quantitative data rather than just qualitative insights, offering a more precise and measurable understanding of the CO₂ storage dynamics. Table 1 shows the type of information obtained from tracer technology applied in K12 and In-Salah projects.
