Investigating Multiphase Flow Phenomena in Fine-Grained Reservoir Rocks: Insights from Using Ethane Permeability Measurements over a Range of Pore Pressures

Figure 6

Dominant pore size calculated using (2) and the helium Klinkenberg plot data. Pores are generally smaller in samples with lower , but with lots of variability around the trend. Dashed line delineates the macropore-mesopore boundary below which capillary condensation is expected at ethane gas pore pressures close to the saturated vapour pressure [6].
