Web1 feb. 2004 · Permeability of the membranes was determined from the slope of the kinetic plots for each of the membrane types ( Fig. 3 ). It is evident from their linearity that diffusion-limited transport is occurring with little back transport, as … Web23 apr. 2008 · It is customary, for convenience, to use relative permeability data produced at room temperature. This paper shows that this practice underestimates oil recovery rates and ultimate recovery from chalk rocks for high temperature reservoirs. Above a certain temperature (80°C in this work) a reduction of oil recovery was observed. The reduction …
