文摘

Liquid and supercritical CO2 permeability in coal at deep, in-situ conditions. High reduction in permeability using supercritical CO2 over liquid CO2. Empirical relations for exponential decline in permeability with effective stresses. Early data on subcritical and supercritical CO2 flow in Indian bituminous coals. N2 effectively reduces loss in coal permeability with very low adsorption.
