WebApr 11, 2024 · The first-contact miscibility occurs when the oil and the injected gas reach miscibility upon their first contact in the reservoir at any arbitrary rate. However, in most cases, gas–oil miscibility develops through continuous mass transfer between the phases, named multi-contact miscibility (Choubineh et al. 2024; Green and Willhite 2024).

WebJan 9, 2024 · When two liquids dissolve in one another, they are miscible. Oil and alcohol are miscible (can mix evenly). The principle of miscibility helps to explain how oil does not mix with water but does mix with … WebThe classical thermodynamics definition of miscibility is the condition of pressure and temperature at which two fluids, when mixed in any proportion, form a single phase. For example, kerosene and crude oil are miscible at room conditions, whereas stock-tank and water are clearly immiscible.
