چکیده انگلیسی
We tried to spotlight the effects of pressure, temperature and composition on interfacial tensions. The findings show that effects of pressure are more profound on IFT rather than temperature. As pressure increases, particularly at low pressure conditions, the gas-oil interfacial tension declines with a descending trend. This behavior continues even at higher pressure with smaller rates. Increases in temperature increase the interfacial tensions as well. The effects of pressure and temperature are linked to the changes in density contrast, mutual gas-oil solubility, and miscibility development. The IFT variation can also be affected by the oil composition and therefore the trends and/or IFT values might change from one fluid system to another. The effects of composition are found to have significant effects on IFT, which depend on the phase envelope of the sample.
