Abstract
The presence of water and gas is common in the offshore oil production scenario. Several techniques, such as the gas-lift and the water-assisted technique, utilize gas or water to increase oil-production productivity. Further research on natural or artificial three-phase flow in oil wells is in order. Several studies on three-phase flow have been published over the last years, but the results so far are not as conclusive as those on two-phase flow. In this work some characteristics of three-phase flow are investigated and compared with available data from the literature. New data of pressure drop and volumetric fraction are reported and different oil viscosities are tested. A classification of flow patterns in three-phase flows is presented as a function of superficial velocities. The hypothesis of no-slip between water and oil is evaluated and the benefits of water and gas injection in the reduction of the total pressure gradient are investigated.
