Multiphase Pumping Systems

Why Multiphase Pumping Systems

Our Two-Screw Multiphase pump systems have been used to pump crude oil in pipelines and on wellpads for over 20 years. The systems efficiently utilize one pump to boost complete, untreated production flows (mixture of oil, gas, condensates, water and/or solids) through multiphase gathering pipelines. The systems simplify surface facilities, eliminating infrastructure associated with separation and independent water, gas and oil gathering systems. Additionally, systems deployed on wellpads reduce well backpressure, increasing oil & gas production.

How Multiphase Systems Work

Our systems utilize positive displacement pump technology combined with industry leading internal (to pump) and external (to pump) recirculation systems to pump the multiphase fluids during oil production.

Primary pump components are two intermeshing, self-priming screws that isolate a volume of liquid and convey it from pump inlet to outlet. Properly timed, the screws overcome conventional pump challenges – running dry, sandy or high GVF flows – as the screws do not contact either each other or their housing. For fluids up to 97% GVF, the pump housing includes an embedded liquid reservoir that releases liquid into the screw mechanisms This liquid maintains proper pump efficiency through optimal internal sealing of the multiphase pump elements and dissipates heat generated from compressing the gas portion of the flow.

A complete system, with fully automatable controls, encompasses the multiphase pump to ensure optimal operations in our constantly changing oil and gas conditions. Motors, strainers, knock-out vessels, balancing and recirculation lines, valves, lube systems and heat exchangers are some of the primary system components that work together to ensure consistent, efficient operations while extending the system’s capabilities to 100% GVF flows.
