An experimental investigation of multiphase gas-oil-water flow was performed for studying the influence of water-soluble and oil-soluble DRPs in single-phase, two-phase, and three-phase flows. These experiments have been presented for oil, air, and water flowing in a 22.5 mm ID, 8.33 m long PVC horizontal pipe. The effect of gas flow rate, water flow rate, oil flow rate, DRPs types, and DRPs concentrations on pressure gradient and flow patterns were investigated. Stratified-wavy, slug, and annular flow regimes were studied. The results showed a large reduction in pressure gradient due to DRPs at high liquid mixture superficial velocity, which was accompanied by significant effect of DRPs on the flow patterns transition boundaries. For gas-water-oil flow, the maximum drag reduction was achieved when water-soluble DRP was used. Moreover, under similar conditions, using oil-soluble or water-soluble may not
