... of time. The multiphase pump downhole assembly (MDA) utilises the obvious advantages of displacement pumps in its contact-free design and therefore allows independent control of the two main conveying parameters, delivery pressure and delivery rate. Multiphase downhole screw assemblies were developed...

... should be considered when designing the individual components. This includes the interaction of the multiphase pumping station with the upstream and downstream flowlines, well and topside process. This paper presents a subsea multiphase boosting system design with integrated controls, covering key...

... lives. One of which is the introduction of multiphase pumps (MPP), which is essentially a mean of adding energy to the unprocessed crude to enable the gas-oil water mixture to be transported over longer distances to the handling station without the need of prior phase separation 1–6 . Many MPPs were...

... Multiphase pumping is around the world for about the last 20 years. There was a "careful" start, mostly with smaller pumps, obviously to minimize a commercial risk with this new technology. Power installed ranged below 300 kW, with exceptions to be found in heavy crude oil applications. However...

... ABSTRACT The conveying characteristic of a twin-screw multiphase pump (MPP) boosting oil and gas is investigated experimentally regarding the dissolving and degassing phenomena that occur due to changes of pressure alongside the flow. The gas volume flow within the total volume flow increases...

... ABSTRACT In the last two years, extensive testing and development has led to a new concept that has successfully demonstrated that the operating envelope of the progressive cavity multiphase pump can be expanded to handle not only higher gas volume fractions, but also much larger volumes...

... ABSTRACT Between August 2003 and May 2004 fourteen large twin screw type multiphase pumps –up to 1.2 MW each – have been delivered to Central Africa. The scope of supply included the pump-motor skid assembly with auxiliary piping external re-circulation system and complete instrumentation...

... Abstract PETROBRAS for more than one decade has concentrated efforts and contributions to the development of the technological route of multiphase pumping – emphasis has been put on the development of a complete system for sub sea deployment. Based on such dedication and working under...

... INTRODUCTION Multiphase pumps are used in the oil and natural gas producing and processing industry to deliver multiphase mixtures directly. The mixtures consist of liquid and gaseous hydrocarbons, water, as well as particles, e.g. sand or crystalline hydrates. The experimentally...

... Abstract. The evaluation of backflow rate and heat transfer in twin-screw multiphase pumps depends on the comprehension of the flow in narrow annular channels with rotation of the inner cylinder. In this pump, the peripheral clearance, which geometry recalls the cited narrow channels...
