\subsection{Modeling results}  In this section we present the results of three five  synthetic seismograms based on seismograms: baseline, after 5,10,15 and 50 years of start of CO$_2$ injection for the Becancour like and  the stochastic geological model. optimistic scenario.  Corridor stacked traces for 4 7  offset are shown for each seismograms. The results for Figure \ref{fig:fig8} shows  the "baseline", the difference between baseline and CO$_2$ injected in the Cairnside layer and between baseline and CO$_2$ in the Covey Hill layers are shown on Fig \ref{fig:fig8}. As demonstrated in Fig \ref{fig:fig8}b and \ref{fig:fig8}c the difference after CO$_2$ injection are caused primarely by the slight shifts between the two images. The shift starts at 0.85 s results  for the model with CO$_2$ on Becancour like scenario. Figure \ref{fig:fig9} shows  the Cairnside layer and about 0.1 s later results  for the model with CO$_2$ in the Covey Hill layer. In the model with CO$_2$ in Cairnside layers (red in Fig \ref{fig:fig8}b), we see a strong increase in the reflection strenght from the Covey Hill formation. \\  The effect of CO$_2$ is mainly observed by a travel-time delay. Other authors reported similar obervations \citep{Yang2014,Arts2004} optimistic scenario.
