... Abstract In this paper we discuss the multiple solutions of the three-phase flow model and how they can be related to the oil and water accumulation and removal for a low liquid loading case. Under certain conditions, a ramp-up of the flow rates results in the liquid being removed in three...

... be especially problematic for some aging deep-water production systems. Severe riser slugging is characterized by large fluctuations of liquid (oil and water) and gas production arriving at the topsides first stage separator. The severe slugging cycle is divided in four steps as described in Figure 1...

... is the twin-screw technology. Twin-screw pumps depend on liquid availability to seal the internal clearances and remove compression and friction heat generated. Different technical solutions to overcome this issue are available. Separation, storage and recirculation of produced liquid are a common way...

... to demonstrate, and quantify, diameter effects in single-phase flow. Further, the effects of DRA in two- and three-phase flow have been studied in a D=100mm pipe. The overall conclusion is that the drag reduction increases with the inlet fraction of the liquid that carries the DRA. INTRODUCTION This paper...

... slug build-up. The third phase is modeled with a mass conservation equation and an oil/water slip model in a mixture liquid momentum equation formulation. 1 INTRODUCTION The introduction of nuclear power generation in the mid 1950s increased the need for accurate and reliable methods to predict two...
