Xtreme Performance Series Motors Increased Average Run Life 74%
CASE HISTORY | bakerhughes.com Xtreme Performance Series Motors Increased Average Run Life 74% Location: Colombia Results XP series motors achieved average run life increase from 708 to 1,234 days Motors from Baker Hughes withstood high bottomhole temperatures Challenges Operator had ESP systems with repeated failures and shutdowns Average run life was 708 days Significant bottomhole temperatures led to overheating and motor failures 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 Baker Hughes solution XP series motors from Baker Hughes were added to ESP systems Improved motor lamination included all-magnetic steel, which reduces bearing heating and increases overall motor efficiency Added outboard bearing in the stator for increased reliability CASE HISTORY 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. XP is a trademark of Baker Hughes Incorporated.
