The theory of multicontact miscible displacements in four-component systems to displacements by a single gas component of an oil containing any number of components is extended. Multicomponent solutions are developed using the method of characteristics in the absence of dispersion and are shown to consist of a series of successive pseudoternary displacements. Analytical solutions are constructed and compared to experimental results for a synthetic ten-component oil displaced by CO2. Extension of the theory for displacement of real oils with an arbitrary number of components is also discussed.
