Successive substitution method for component concentration calculation during compositional modeling of hydrocarbon field development
A system of conservation equations for multicomponent flow modeling and a generalized equation of state are considered. An algorithm for determining the concentration of components in phases is described in detail using the method of successive substitution. An example of the implementation of this scheme for simulating alternate injection of gas and water in the development of an oil field is considered. An indirect confirmation of the model correctness is obtained
