Fig. 2. Comparison of time-lapse photographs of the experimental observations with selected simulation results, taken (from left to right) 30, 60, 180, 300, and 600 min after the onset of injection at the top boundary. (a) Time-lapse images of one experiment showing typical behavior, (b) the ECM model results, and (c) the "calibrated" discrete fracture model results (mf = 0.8). Note, the blue color in the simulation results indicates the initial liquid saturation of the matrix (
7%) while the red indicates 100% saturation.
