A customer operating a water flood with 1% oil cut in northeastern Oklahoma was experiencing extensive nonproductive time (NPT) and rising maintenance costs caused by a triplex pumping system to re-inject 28,000 barrels of produced water daily.

To reduce downtime and improve efficiency, Baker Hughes, a GE company (BHGE), recommended replacing the triplex pump with a highly reliable, efficient parallel HPump™ horizontal pumping system paired with a BHGE Electrospeed™ 3 variable speed drive.

The HPump system consists of a multistage centrifugal pump, a horizontal thrust chamber, and an industrial, footmounted electric motor—all attached to a sturdy skid. Optimized with more than 1,000 hours of research and development testing—plus thousands of worldwide installations—the durable and simple HPump system lowers operation and maintenance costs. In this case, the customer saw maintenance expenses decrease 80%, while production increased 67%. The HPump system also saved USD 246,700 in annual deferred production costs compared to the previous system.
