Permeability is difficult to evaluate in reservoir petrophysics property, especially in low porosity–permeability reservoir. The conventional permeability estimation model with establishment of the regression relationship between permeability and porosity is not applicable. This regression hypothesis based on the correlation between porosity …

This research reveals that the solvation effect influences the rate of crystal nucleation and growth, leading to variations in the ratio of micropores to mesopores and overall porosity in MIL-101(Cr)-XmM. The high porosity of MIL-101(Cr)-1.6 mM facilitates a higher diffusion rate of particles and exposes a greater number of alkaline sites.
