The alteration of the wettability from liquid-wetting to intermediate gas-wetting results in improved liquid mobility, which has been demonstrated by a number of authors in recent years. In this work, we show that the gas-phase mobility may either increase or decrease in the state of intermediate gas-wetting. The increase or decrease in the gas-phase mobility is a function of the minimum liquid saturation. We also confirm that, as a result of the wettability alteration, there may be a substantial decrease in the two-phase high-velocity coefficient compared to the unaltered wettability state. The increase in the gas- and liquid-phase relative permeabilities and a decrease in the high-velocity coefficient of the two-phase flow from the wettability alteration contribute to improved gas well productivity. 2 Journal of Canadian Petroleum Technology 50 ARTICULO Wu, Stanley 45027 Firoozabadi, Abbas 20045 185431 185431 0 0 0 0 253250 BAAB BAAB 2026-03-06 200057507 0 200057507 2026-03-06 00:10:44 2026-03-06 ARTICULO
