Characterizing the Evolution of Trapped scCO₂ Curvature in Bentheimer and Nugget Sandstone Pore Geometry

Figure 6

Grain contact surface: (a) scCO₂ ganglion trapped in Bentheimer pore in contact with four grain surfaces (geometric contact angles are shown in red on both sides of contact), (b) same scCO₂ ganglion trapped in Bentheimer pore in contact with six grain surfaces (the teal voxels represent the 3D contact line), and (c) 3D view of same pore showing ganglion in contact with six total surfaces where each color represents a different surface.
