This paper is to describe the application of an integrated multiphase flow model on production allocation and timing of compressor installation in gas fields, which have multi-wells and multi-reservoirs. In order to depict flow in reservoir and surface pipeline network (wellbore to market) simultaneously, an integrated multiphase flow model has been developed. The integrated reservoir and surface network flow model includes various sub-models such as a compositional model, a reservoir model, a pipeline multi-phase flow model, a surface network model, and a reservoir-network interfaced model. The integrated model has been applied in Donghae-1 gas field. As a result, the field life has extended through production optimization, and the installation timing of compressor has been delayed.
