Oil Production: Saving Energy and Money with Positive Displacement Screw Pumps
Globally, oil production trends have mitigated towards increasing pipeline diameters and greater oil volume throughput from both onshore and offshore oil fields to downstream production facilities. In part this trend is fuelled by a need to reduce the carbon footprint of the producer but also to reduce the cost of production using economies of scale, reduced maintenance and replacement cycles and increasing efficiency and reliability.
In addition, much of the global transportation infrastructure is in the middle of a huge reorganization and refit, so many of the previously accepted standards are being revised in the light of modern and forecasted developments.

The largest three-screw crude oil pipeline pump is capable of being fitted into 24 inch diameter pipes and can pump 85,000 barrels of oil per day under 2,000 pounds per square inch. The oil industry needs the capacity of these new generation pumps to meet the stringent constraints being imposed upon them by the environmental lobbyists and government agencies involved, but at the same time by shareholders who have experienced a severe battering in the economic situation prevailing at present.
Centrifugal pumps no longer can be relied upon to deliver the reduced carbon footprint or the financial benefits. It is not simply these two key factors which have stimulated the development of positive displacement pump technology; new generation pumps are capable of being retrofitted to old-style infrastructure which provides even greater scope for cost savings and carbon reduction.
Crude oil pipeline designs are increasingly calling for positive vane displacement pumps because of the cost savings and the 30 year track record of this pump type in some of the most extreme and harshest environments encountered in the world. Screw pump operation also delivers high volume/high operating efficiency with increased maintenance and replacement cycles such that where fitted, the operator can experience up to 30% reduction in overall costs associated with the installation.
