Abstract
The aim of this work is to experimentally determine the pressure drop in a ESP turned off. So, the main contribution of this study is to provide experimental correlations for local pressure drop that make it possible calculate the system curve and simulate an alternative production system. These results are essential for evaluating feasibility of the production layout studied. For this purpose, an experimental setup with the same ESP installed in the oil field was used to measure the pressure drop. The tests were carried out on oil single-phase flow at different flow rates and viscosities. In addition, gas-liquid two-phase flow tests were performed to investigate the gas influence on the pressure drop. The oil single-phase tests indicated the power law dependence between the loss coefficient and the Reynolds number. Based on these correlations, an estimative of the oil field pressure drop was performed. This study indicates a high pressure drop for the design conditions, requiring a careful evaluation of the production layout. The gas-liquid two-phase flow tests are in progress and will be presented in the final paper.
