The dispersed clays were observed to have substantially higher porosity than the laminar clays. For this reason, clay laminae, and pore-filling dispersed clays are allowed to have differing properties...

... Abstract Unconventional shale reservoirs have complex lithology, porosity and fluid systems where hydrocarbons are stored in both inter- and intra-particle pores. Hence, conventional log measurements and petrophysical techniques often fail to provide a consistent analysis for key petrophysical...
