Expected, ensemble average values of the flow arrangement variables for different values of the capillary number, Ca, and viscosity ratio, κ. (a) Saturation, S_w; (b) volume fraction of connected pathway flow (CPF), β; (c) volume fraction of ganglion dynamics flow (GD) within the disconnected oil flow (DOF), ω. Arrows indicate increasing Ca values: →10⁻⁸ ≤ Ca ≤ 10⁻⁴ and - - - -> 4 × 10⁻⁷ ≤ Ca ≤ 10⁻⁴.
