The large percent of clay present is most likely the cause of <br />• the zero permeability. <br />The two kerosene saturated cores are tested for permeability to <br />kerosene by flowing kerosene through each core. <br />The same procedure is followed using kerosene as is used for <br />the water. Five ml. of kerosene is flowed, and the time is <br />measured. <br />Note: Again, the two cores show no permeability. The kerosene <br />will not flow through either core (held 2.0 Atm d P for <br />30 minutes and no flow is detected). <br />Thus, the permeability to kerosene = 0.0 and <br />The movement of fines within the core pores could have a large <br />. effect on the permeability. The clay present in the core is <br />blocking liquid flow. (See the Permeability work sheet). <br />Two cores are measured for permeability to air by flowing air <br />through the core under a given ~ P. The flow reading is then <br />converted to a flow rate using calibrated charts. <br />Pb qm µ L (2000) <br />k = A [PiZ - PoZ] <br />Nand <br />Where qm = cc/sec. <br />~ cp <br />L = c <br />A = cm2 <br />P = Atm <br />• <br />9 <br />
