Abstract: A method includes modeling a fluid flow network, the fluid flow network having a surface pipeline network connected between a plurality of well perforation nodes and a common outlet or inlet. The method also includes generating a plurality of two-phase envelopes for the modeled fluid flow network, where each two-phase envelope has at least some interpolated values and corresponds to a section of the modeled fluid flow network with a constant flow composition. The method also includes determining phase equilibrium information for the modeled fluid flow network based on the generated two-phase envelopes. The method also includes applying the determined phase equilibrium information to production or simulation related to the fluid flow network.
