Figure 20.
Example of fluid pressure evolution within the domain of each layer at t = 0.1, 1, and 5 yr. The arrows show the orientation and magnitude of the flow in logarithmic scale. The horizontal axis is the reservoir length, and the vertical axis is sum of the layer 1 (bottom layer) and layer 2 (top layer) thicknesses. Results in this figure correspond to the Wolfcamp A model (see Table 3).
