... with the highest affinity for the solid surface is called the wetting fluid, whereas the other is called non-wetting fluid. In immiscible state in the reservoir, oil and brine formed with grain a mixed wet system (Salathiel 1973), whose equilibrium depends primarily on the surface tension between each pair (Tang...

... a ternary phase system formed between the extracting fluid (CO 2 ), a heavy crude and brine which exist within the reservoir, not only this work has addressed the issue of heavy oil recovery using CO 2 as extracting fluid but also, it has demonstrated the combined effects of gas solubility and acidity...

... measured the threshold capillary pressure and have studied the effects of different injection gases on the threshold capillary pressure. One mud rock core plug was used throughout this work. The porosity was estimated at 30.4% by High Pressure Mercury Injection (HPMI) and the water (NaCl brine...
