Figure 10--Comparison of baseline (B), monitor 1 (1), and monitor 2 (2) IF plots with wells located (a). The area highlighted possessed notable changes in data character, intensity, and/or texture between the three surveys. Changes between surveys are not necessary consistent due to a variety of reasons (equalization, changes in reservoir, etc.), but the changes observed within the highlighted area seem to suggest that as the CO2 has progressed the subsurface in proximity to the injector is experiencing changes.
