Indices for the directional, irreversible pseudo-relative permeability tables in the truth model for the X+ (a), X− (b), Y+ (c), and Y− (d) directions. (e) The host rock and eight pseudo-relative permeability functions shown with the same color scheme as (a–d). (f) As (e), but limited to the water saturation range in which the functions are variable. Crosses are for oil, circles are for water.
