Figure 4 Before CO2 injection (top) compared to after CO2 injection (bottom). Reflections from the L-KC should be arriving around 600 msec (+/- 100 msec). Exact time depths are being determined from VSP and synthetic seismograms produced from nearby sonic logs. The boxed areas are enlarged in Figure 5.

Reflections from time before CO2 injection

Reflections after CO2 injection are showing subtle changes
