Method optimizes Aghajari oil field gas lift

05/21/2001
A new approach determined gas-lift valve spacing for an optimized artificial-lift system in the Aghajari oil field in southwestern Iran.The field produces more than 195,000 bo/d.The optimization study used pressure-volume-temperature (PVT) data combined with fluid and multiphase flow correlations. A well's gas-lift performance curve was constructed based on actual pressure and temperature surveys and the gas injection point determined from the study.A nodal method obtained the optimum injection depth, optimum wellhead pressure, optimum producing rate, and minimum injection gas volume.The study showed that considerable gains in efficiency could be realized by implementing this optimiza...
