How to calculate two-phase flow of gas and oil in pipe lines

Abstract

Research programs have been developed to design two-phase flow lines accurately. Flowlines joining oil and gas production wellheads to processing units usually transport a two-phase gas/liquid mixture. As long as the wells are flowing and the processing unit is not too far from the producing field, few problems in designing and operating flowlines may occur. For gas-lift wells or for wells located far away from the processing units, transport pipe lines represent a major investment. The prospect of production from deepsea reservoirs gives added interest in two-phase evacuation pipe lines.
