WebFor conditioning at 50°C, the permeability was measured with a gauge pressure of 5 bars, while for 80°C and 105°C this pressure was no more than 1 bar. The results for permeability as a function of drying time and degree of saturation of the samples are given in Figure 4. It can be seen that the permeability varies markedly with drying time. WebAn average permeability can also be calculated from production-history data by adjusting permeability until the correct history of production is obtained. Multiphase Flow Permeability in a porous medium that is 100% saturated with a single-phase fluid is the absolute permeability, or synonymously, the intrinsic permea-bility or specific ...
