The analytical theory of one dimensional, dispersion free miscible displacement of
oil by injection gas with nc component has shown that: the MMP is the lowest pressure at which any
one ofthe initial oil, injection gas or crossover key tie lines becomes critical, which means that its
length approaches to zero. In this paper, we propose a methodfor a solving multi component system
based on analytical calculation of ternary systems, which simplifies and converts the multi
component system into a pseudo ternary system and estimates the minimum miscibility pressure
without solving complex and time consuming equations ofcrossover tie lines.
