The results of the minimum miscibility pressure (MMP) determination for miscible injection of CO2 and an associated gas of one of Iranian gas reservoirs into two different oil samples using a slim tube device are presented. For an effective determination of the MMP cell-to-cell slim tube simulation was performed for each case before performing the slim tube experiment and the results were used to determine the pressure intervals in the slim tube experiment. A comparison between the measured MMP values from the slim tube experiments and those calculated by cell-to-cell simulation revealed that the cell-to-cell simulation can be a substitute to slim tube test in cases where time is a primary...

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...
