In this paper we study how the calibration or non-calibration of the oil PVT properties and the two-phase flow correlations influences the vertical lift performance curve in the case of naturally flowing well. Several working scenarios regarding the calibration, respectively non-calibration of the oil PVT properties as well as the two-phase flow correlations were considered. This study shows a small influence of oil PVT properties (calibrated or non-calibrated) on the pressure traverse curves and consequently on vertical lift performance curves. On the other hand, the calibration of the two-phase flow correlations is very important; the results before calibration and after calibration being very different. Also, a practical aspect related by the number of measured data used in calibration process is shown.
