Fig. 5. Shading indicates the mass fraction of CO₂ in the gas phase, labeled contour lines indicate the water saturation, and vectors indicate the pore velocity of the gas phase for the base case at steady-state seepage rates with a leakage rate of (a) 4 x 10⁴, (b) 4 x 10⁵, and (c) 4 x 10⁶ kg yr^-1. The maximum vector size represents a value of approximately (a) 0.057, (b) 0.53, and (c) 3.6 m d^-1.
