As part of the VMPT joint research project (which stands for networked, multiphase transport technology) funded by the German Federal Ministry for Economic Affairs and Energy (BMWi), a multiphase pump down-hole unit (MDA) was developed and its integration into multiphase transport networks investigated. The multiphase pump down-hole unit (MDA) takes advantage of the principles of positive displacement pump design and was developed for two main uses: 1. Conveying gas-containing hydrocarbons - this allows an installation of the MDA close to the formation 2. Pumping of liquid loaded gas wells. With its ability to pump oil and gas in almost any fraction, this machine extends the usage range of down-hole pumps. This contributes to the ability to exploit fields which are hard to extract. Field experience in Ecuador has shown that the combination of down-hole pumps with multiphase pumps installed above ground requires careful adjustment. Associated studies of multiphase transport networks show that multiphase twin-screw pumps installed in series both in the well and above the ground enable oil and gas resources to be extracted in a way that is very economical and safe for the environment. The work was supplemented and supported by project partners from universities on the topics of corrosion and wear, exploration geology, reservoir simulation, thermodynamics as well as verification concepts for operational stability and reliability. © 2015 URBAN-VERLAG Hamburg/Wien GmbH.

Since the start of commercial applications of multiphase pumps, their installations have increased steadily. Today a number of reputable manufacturers offer a widespread pump range in regard to flow rate and pressure building capability. However, the foremost working principle still 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 for this. However, pumps installed in parallel require special attention in regard to upstream flow splitting. This is especially true for multiphase pumps being fed by wells which are far away, as long gas slugs have to be envisaged. The operation of multiphase pumps requires observing up- and downstream flow scenarios, as well as detailed knowledge of the entire (pumping) process. Furthermore potential solids production has to be taken into account. Source
