Multiphase Pumping Systems Overview

Multiphase Pumping for Better Economics in Oil and Gas Production

Conventional methods for producing oil and gas are successfully replaced by a simpler, more economic technology known as multiphase pumping. Multiphase pumping does not require separation of oil, gas, or water, so production from the field can be gathered and transported to a central processing area without requiring separate flow lines, separators, heater-treaters, tanks, flares, stock pumps and compressor: Multiphase pumps can handle low inlet pressures, which make them ideal for lowering the flowing backpressure of the well. With many wells, particularly those on artificial lift, substantial gains and accelerated production can be achieved with even a modest drop in back pressure – enough to in many cases justify the investment within a few months.”



Leistritz Multiphase Pumps are built for use offshore, onshore or in subsea installations and are available in both a high pressure and a low-pressure design. They are ideal for a broad range of oil viscosity and emulsions and work very well with high GOR. The pumps are made to cope with slug flow with no impact on operations, High GVF (Gas Void Fraction) as well as wet gas are handled with recirculation of liquids. The compression heat is removed with the liquid and no process coolers are required.


Twin screw pumps are ideal for multiphase pumping because they are positive displacement machines working independently of density and inlet pressure as well as backpressure and changes in GFV (Gas Void Fraction). During the life of the field multiphase flow can be easily controlled by controlling the speed of the pumps. The pumps are built to handle 100 % GVF eliminating the need for slug catchers or inlet scrubbers.
