Most of them are evolutionary, but there are at least three revolutionary technological changes that may shape the future. These are the use of powder metallurgy in manufacturing submersible pump stages, the application of permanent magnet synchronous electric motors, and the rise of a new pump technology: the V-pump. The new stage manufacturing process produces more complex pump stages (which are more and more frequently designed by CFD methods) and permits to reach very high pump efficiencies never seen before. Such stages are inherently more balanced than their casted counterparts and can be used at exceptionally high speeds. At high speeds, pump stages develop greatly increased hydraulic heads, so less stages are required and the length and weight of submersible pumps decrease significantly. The application of permanent magnet motors in other industries is quite widespread: the ESP industry has just started using them. Their advantages are numerous, but the most important is the lower power requirement and the longer service life, as compared with present-day induction motors. In the present scenario of low oil prices the proven 10%e30% reduction in production costs is so desirable that the number of ESP installations using permanent magnet motors grows exponentially. The totally new pump type called V-Pump excels in conditions detrimental for centrifugal pumps: high viscosity fluids, abrasive solids, or gas problems. Driven by a usual ESP motor, this pump can work under such adverse conditions where no submersible centrifugal pump could operate; it surely will expand the application ranges of ESP operations in the near future. One does not need ESP (this time extra-sensory perception) to predict that these revolutionary developments will soon become part of the daily routine in ESP operations.

Description: Since the publication of the first edition of this book in 2009 many important
developments have occurred in the electrical submersible pumping (ESP) industry.
Most of them are evolutionary, but there are at least three revolutionary
technological changes that may shape the future. These are the use of powder
metallurgy in manufacturing submersible pump stages, the application of permanent
magnet synchronous electric motors, and the rise of a new pump technology:
the V-pump. The new stage manufacturing process produces more
complex pump stages (which are more and more frequently designed by CFD
methods) and permits to reach very high pump efficiencies never seen before.
Such stages are inherently more balanced than their casted counterparts and can
be used at exceptionally high speeds. At high speeds, pump stages develop
greatly increased hydraulic heads, so less stages are required and the length and
weight of submersible pumps decrease significantly.
The application of permanent magnet motors in other industries is quite
widespread: the ESP industry has just started using them. Their advantages are
numerous, but the most important is the lower power requirement and the longer
service life, as compared with present-day induction motors. In the present
scenario of low oil prices the proven 10%e30% reduction in production costs is
so desirable that the number of ESP installations using permanent magnet motors
grows exponentially.
The totally new pump type called V-Pump excels in conditions detrimental
for centrifugal pumps: high viscosity fluids, abrasive solids, or gas problems.
Driven by a usual ESP motor, this pump can work under such adverse conditions
where no submersible centrifugal pump could operate; it surely will expand the
application ranges of ESP operations in the near future.
One does not need ESP (this time extra-sensory perception) to predict that
these revolutionary developments will soon become part of the daily routine in
ESP operations.
