Abstract

This work concerns with experimental and analytical investigation of role of ultrasonic wave radiation in relative permeability of both wetting and non-wetting phases in a free gravity drainage process in porous media under the influence of ultrasonic wave. Glass beads ranged from 70 to 100 mesh sizes were packed and used in the tests. The working fluids consist of distilled water, kerosene and Doroud and Paidar crude oils as wetting and air as non-wetting phase. The measured oil recovery data along with Hagoort (1984) backward methodology were used to determine and to compare the relative permeability of wetting phases in presence and absence of ultrasonic radiation. In addition, the relative permeability of non-wetting phases for both cases was calculated from inverse modeling of provided data. The results showed that wave enhanced the relative permeability of phases, except than for the case of Paidar crude oil, which is asphaltenic. According to this study, it is proved that wave radiation increases the relative permeability of both wetting and non wetting phases. Although, the results where adverse in the case of asphaltenic crude oil which could be justified as a result of breakdown and dissociation-dissolution of asphaltene particles.
