Permeability evolution of two sedimentary rocks at different temperatures based on the Katz-Thompson theory

Previous researchers have shown that the Katz–Thompson theory is useful in predicting permeability of sedimentary rock from mercury intrusion porosimetry data. In this paper, the variations in pore characteristics of sandstone and limestone in the temperature range of 25 °C–600 °C are studied based on mercury injection test and the permeability evolution is also analyzed. The results show that the permeability of sandstone fluctuates and can be...
