Figure 12: Acyclic pore network model for a pore structure where the pores most responsible for limiting fluid flow are in the macropore range ((a) and (b)) and mesopore range ((c) and (d)). Solid red lines indicate pores filled with liquid/semiliquid ethane. Ethane capillary condensation at high pore pressures completely blocks off the highest flow capacity flow paths in the mesoporous pore network (d) but has a limited impact on flow capacity in the macroporous pore network (b). Pore network models are modified from Sakhaee-Pour and Bryant, 2015.
