Determination ofMinimum Miscibility Pressure by Analytical Method

The analytical theory of one dimensional, dispersion free miscible displacement ofoil by injection gas with nc component has shown that: the mmp is the lowest pressure at which anyone ofthe initial oil, injection gas or crossover key tie lines becomes critical, which means that itslength approaches to zero. in this paper, we propose a methodfor a solving multi component systembased on analytical calculation of ternary systems, which simplifies and converts the multicomponent system into a pseudo ternary system and estimates the minimum miscibility pressurewithout solving complex and time consuming equations ofcrossover tie lines.
