coal seams as it causes coal seam permeability to be significantly reduced. The main objective of this study was to … investigate the effect of coal mass swelling on the permeability of naturally fractured black coal. A series of permeability tests … corresponding effects on CO2 and N2 permeabilities were examined. Results indicate that the permeability of naturally fractured …

. Therefore, the permeability of well cement should be low to avoid leakage in the wellbore. To date, ordinary Portland cement … discusses its permeability. In the first phase of this work, previous studies relevant to the permeability of existing oil well … permeability of geopolymer under tri-axial conditions, using the high pressure tri-axial set-up available in the Monash University …
