The crosspiot in [[:file:migration-of-petroleum_fig7-10.png|Figure 1]] shows the difference in relative permeability at varying [[water saturation]]s for bed-parallel vs. bed-perpendicular [http://www.bakker.org/dartmouth06/engs150/14-multi.pdf multiphase fluid flow] in a wavy bedded rock. The water saturations need to be much lower in bed-perpendicular flow to achieve the same relative permeability. The flow within a bed is a function of the proportions of end-member lithologies, their permeability and [[capillary pressure]]s, and the orientation of the beds to the direction of the flow.
