• PERMEABILITY MEASUREMENTS <br />Date: January 20, 1983 <br />Time: 8:00 a.m. <br />Permeability is measured by using a Ruska Air and Liquid permeameter. <br />Air, water, and Kerosene is used as the flowing media. <br />Ruska Liquid Permeameter <br />The four H2O saturated cores are tested for k to water by <br />flowing water through each core. <br />The Ruska Permeameter uses the time required to Elow 5 ml of <br />liquid through a core which is placed under a .25 to 2.0 Atm <br />pressure differential. <br />q u L (1000) <br />k = <br />A P <br />.~ and <br />where q = cc/sec. <br />~ cp <br />L=cm <br />A = cm <br />p P = Atm <br />Note: All four H2O saturated cores would not allow water to <br />flow through. (A 2.0 Atm OP is used and is held for <br />approximately 30 minutes and still no floe is detected). <br />(See the Permeability work sheet). Thus, the <br />permeability to water 0.0 md. <br />u <br />8 <br />
