injectivity. Moreover, the Covey Hill is found at a depth with PT conditions that will maintain CO$_2$ in a supercritical state. \\  The CO$_2$ could also be injected in the Cairnside (upper Potsdam), however its hydrogeological and petrophysical properties are less favorables to store CO$_2$ \citep{TranNgoc2014}. Moreover, the temperature gradient of B\'e\-can\-cour reservoir (23.5 $\pm$ 0.6 $^{\circ}$C/km) may not lead to a supercritical state of CO$_2$ everywhere in the Cairnside Formation, due to the higher location of its formation top \citep{Claprood2012}.\\  The regional caprock unit consists of the Utica and Lorraine shales. The thickness (\textgreater\ 800 m) and permeability (1 x 10$^{-4}$ mD) of the caprock units in the B\'e\-can\-cour region are apparently capable of preventing  buoyancy-driven migration of injected CO$_2$ to the surface, as they have maintained over-pressured conditions in the saline aquifers \citep{TranNgoc2014}. Petrohysical and hydrogeological properties of the reservoir are resumed on Table \ref{table 1}. \begin{table}  \centering  \caption{Physical properties of the Potsdam group sandstones}  \scalebox{0.7}{  \begin{tabular}{@{}lccccccc@{}}  \toprule  Sample & Lithology & Grain Density\tnote{b} & Porosity\tnote{a} & Matrix Permeability\tnote{a} & Salinity\tnote{a} & net pay thickness\tnote{a} & Pore size\tnote{b} \\  & & \small{[$g/cm^3$]} & \small{[\%]} & \small{[$mD$]} & \small{$mg/l$} & \small{$m$} & \small{[$\mu m$]} \\  \midrule  Cap rock & shale & 2.700 & 4 & 1 x 10$^{-4}$ & - & \textgreater\ 800 & - \\  Cairnside - CA & sandstone & 2.632 & 4 & 0.11 & 241.800 & 68 & 0.55 \\  Covey Hill - CH & sandstone & 2.613 & 6 & 0.26 & 108.500 & 196 & 0.55 \\  \bottomrule  \end{tabular}}  \label{table 1}  \end{table}
