Gas lift system is optimized by use of PVT data combined with fluid and multiphase flow correlations. The first step in the study is the selection of appropriate correlations followed by multiphase flow calculations at various points of injection. From actual pressure and temperature surveys and determining the point of injection, a gas lift performance curve is constructed for the well. In order to determine the optimal gas lift condition, Solution nodal method is used to determine optimum injection depth, optimum well-head pressure, optimum production rate and minimum injection gas volume. A considerable gain could be obtained from implementing recommendations. Finding the appropriate valve space is done in this work is new compared to others.
