Hydraulic Pumping Units

Innovative pumping units for unconventional wells and heavy oil

KUDU HPU hydraulic pumping unit.

Enhance lifting system efficiency and optimize your performance

Schlumberger hydraulic pumping units are offered for a wide range of well applications and have a small footprint, compact and lightweight design, quick installation, and the ability to easily adjust stroke speed and length—either onsite or remotely. Installation takes less than 6 hours, whereas 2 to 4 days are required for transport and assemble conventional systems.

Providing flexibility to suit various well conditions, the HPUs are electric or gas powered and available in cylinder lengths of up to 240 in [6.1 m] and a peak polished rod load capability of up to 40,000 lbm [18,144 kg]. Stroke lengths of up to 240 in reduce cyclic stress, minimize rod stretch impact, improve gas compression ratios, minimize the possibility of gas lock, and enhance overall system efficiency. Long strokes enable our hydraulic pumping units to maintain production at slower pumping speeds, thereby reducing frictional losses in highly deviated and horizontal wells.

Reduce HSE risk

The hollow cylinder is installed directly on the wellhead, reducing space requirements and eliminating the need for concrete pads, guide wires, and special site preparation.

Pump more efficiently in unconventional wells and heavy oil

Horizontal shale wells exhibit rapid production declines. An artificial lift system that has a wide operating range eliminates the capex needed to change systems at a time when well production is tapering off. The system must also be capable of handling multiphase fluids, abrasive solids, and small liner IDs.

Our hydraulic pumping units enable adjustment of the pump’s velocity profile in a matter of minutes to accommodate changing production throughout the life of the well—without the expense of variable frequency drives or manipulation of large counterbalance weights. The units are SCADA ready, so they can be easily connected to your internal SCADA monitoring system or a third-party system for rapid remote data access and other features.

The hollow cylinder design is suitable for high-temperature, heavy oil applications

The hollow cylinder design performs reliably in reservoir ambient temperatures to the elevated temperatures associated with the thermal recovery of heavy oil. Their ability to handle multiphase flow, steam breakout, and solids production further enhances their suitability for heavy oil applications.
