Experimental studies on nanopore evolution in organic matter-rich shales
Published 2021-08-01“…The experimental results are summarized as follows. (1) The pore volumes of the shale samples with different maturities all increased in the pyrolysis simulation, but pore volume increases observed in the matured sample were higher than those in the over-matured sample. (2) Laboratory pyrolysis experiments can increase organic matter (OM) micropores when the gases are generated from the kerogen/bitumen/oil. (3) As maturity increases further, OM micropores become connected together by the formation of new micropores, forming mesopores or even macropores. (4) In the processes of hydrocarbon generation, the kerogen type and carbonate mineral recrystallization or dissolution also have a great influence on the evolution of pores.…”

Pore throat characteristics of tight sandstone of Yanchang Formation in eastern Gansu, Ordos Basin
Published 2018-03-01“…The permeability is mainly controlled by the large pore throat (>R50) which accounts for a small proportion; in the tight sandstone with the permeability greater than 0.1 mD, the permeability is mainly controlled by the micropore and mesopore; in the tight sandstone with the permeability smaller than 0.1 mD, the permeability is mainly controlled by the nanopore and micropore; the proportion of small pore throat increases with reduction of permeability, it is important that the small pore throat influences the reservoir storage property though its effect on permeability are small. …”
