An operator in Colombia had electrical
submersible pumping (ESP) systems that
experienced repeated shutdowns and system
failures. Average run life was 708 days.
After hearing about the Xtreme Performance
series (XP™) motors from Baker Hughes,
the operator wanted to see if the motor
would withstand this field’s harsh operating
conditions, improve run life, and increase
reliability rates.
Previous ESP systems had poor motor
performance due to high bottomhole
temperatures and low flow rates past the
motor. This caused problems with system
cooling. Mechanical vibration in both the rotor
bearing and head/base bushing also impacted
system component stability and reliability.
Baker Hughes Artificial Lift Systems developed
the XP series motors in response to operator
requests for improved reliability and increased
run life in harsh operating conditions.
These motors are backed by Baker Hughes
industry-proven motor technology, which is
demonstrating unsurpassed reliability in wells
around the world.
The XP motor features a number of design
improvements when compared to the motors
from several competitors in Colombia.
Examples of motor enhancements include a
change from stainless steel to all-magnetic
steel in the motor lamination, which reduced
bearing heating and increased overall motor
efficiency. Motor components were more
wear tolerant and vibration resistant. Dual
T-ring construction and outboard bearing in
the stator improved reliability. The bearings
between the rotors as well as at the motor
head and base bushings are compliantly
mounted carbide for improved mechanical
stability, reduced vibration, and improved wear
characteristics. The motor thrust bearing had a

higher load capability and offered increased
durability, which was more tolerant of debris.
The operator installed several XP motors
in one of their large, onshore operations
where Baker Hughes has supplied ESP
systems for many years. Baker Hughes was
able to compare average run life rates of
ESP systems with XP motors to those of ESP
systems with motors supplied by competitors.
This comparison was over a period of several
years with competitor motors previously
installed in the same wells. Baker Hughes
reliability experts have data from multiple
wells within this field. Analysis of the ESP
systems in this set of wells indicates that
the XP motors have a significant reliability
advantage. Run life increased 74% from
an average of 708 days with competitor’s
motors to 1,234 days with XP motors.
The operator was pleased with the
improvement in run life and reliability and
will use Baker Hughes ESP systems with XP
motors in future installations.
