Abstract

In this work holdup is estimated through image processing and compared with the value calculated indirectly by the correlation presented by Rodriguez et al. in [1]. The tests were performed in the multiphase-flow test facilities of the Research Centre (CENPES) of PETROBRAS, Brazil. Flow images were obtained with a high-speed video camera at 1000 fps in a 2 7/8-inch and 300 meter deep pilot-scale well, conveying a mixture of heavy crude oil (2000 mPa.s and 95 0 kg/m3 at 35 °C) and water at several combinations of the individual flow rates. In total, four tests were carried out with 100 images each.
