SPE 144050 Submicron-Pore Characterization of Shale Gas Plays

the corresponding throat radius is 0.12 ?m, then throats smaller than 0.12?m and pores controlled by them are not able to be measured[15]. Additionally, the two testing technologies of mercury porosimetry are expensive, time-consuming and core-contaminating. There is not a simple effective method to describe the aspect ratio. Forecast of the aspect ratio requires the choice of (1) a simple
