The RTM results illustrating the effects of \(\hbox {CO}_2\) injection on shallow and deep formations are as follows: (a) and (b) represent the differences between the 25th year during \(\hbox {CO}_2\) injection and the 100th year after injection cessation for shallow Fm. A’s monitor seismic data and baseline seismic data, respectively. Similarly, (c) and (d) show the differences for deep Fm. B. The selected rectangular box indicates the area used for spectrum calculation to quantify the attenuation effects caused by \(\hbox {CO}_2\) injection using the spectrum ratio method.
