... Abstract This paper introduces an analytical approach for generating the inflow performance relationships (IPR) of different reservoirs depleted by different wellbore types at different conditions. The main focus of this paper is given to multiphase flow (oil, gas, water) and two-phase flow (oil, gas...

... of the influential factors in observing various flow regime types is that liquid and gas velocities are not the same in multiphase flows. Stratified flow tends to occur in downhill and horizontal flows that have a low gas and liquid flowrate. When the gas velocity is increased, it becomes a stratified wavy flow...
