EFFECT OF TEMPERATURE ON PERMEABILITY RATIO OF DIFFERENT FLUID PAIRS IN TWO-PHASE SYSTEMS

Abstract

Experiments involving isothermal displacements of refined oil by water, nitrogen, and steam were carried out in unconsolidated sandpack to study permeability ratio temperature dependence over range 95 to 540 F; computed gas-oil permeability ratios indicate temperature dependence probably caused by increase in gas-phase molecular activity with temperature, extension of Klinkenberg effect.
