The pump in the L300 multiphase wellhead system is the model L4MG 200/45 AHOKRO-G in high temperature execution. It is driven by a VFD controlled 400 HP electric motor at 1,800 RPM with the ratio 3:1 turndown. (Image source: Leistritz)
Multiphase pumping is an economic solution for ageing oilfields, where, over time, the natural reservoir pressure drops off to a point where some wells lose the ability to overcome the back pressure generated by the surface flow lines and the first stage separator of the process facility
