Hydraulic Pumping Units

Innovative pumping units for shale wells and heavy oil

Schlumberger hydraulic pumping units are a compact, lighterweight alternative to conventional beam pumps. They are particularly suited to pumping efficiently from long, horizontal, gassy wells.

Single pump through life of well

Horizontal shale wells exhibit rapid production decline. An artificial lift system having 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. You can remotely view and access important real-time well data and respond quickly to changing well conditions and optimization opportunities. Options for remote speed adjustments are also available.

High-temperature rating for heavy oil

These lifting systems are reliable from reservoir ambient temperatures to the elevated temperatures associated with thermal recovery of heavy oil. Their ability to handle multiphase flow, steam breakout, and solids production further enhances their suitability for heavy oil applications.

Multiple advantages of long strokes

Stroke lengths of up to 336 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 lower pumping speeds, thereby reducing frictional losses in highly deviated and horizontal wells.

Lower costs and shorter time to first oil

The small size and footprint of wellsite equipment reduces the cost of transportation, infrastructure, and installation. Installation time is just a few hours compared with the two to four days needed to transport and assemble conventional systems. Improved system reliability and the fewer tubing changeouts as a result further reduce downtime and costs.

Reduced HSE risk and environmental impact

Operator safety improves because all moving parts are enclosed. Maintenance can be performed on one well while neighboring wells remain on production. The unit attaches directly to the wellhead, reducing space requirements and eliminating the need for concrete pads, guide wires, and special site preparation.

No risk of produced fluid leaks

Fully enclosed actuation cylinders prevent hydraulic fluid leaks, which cause downtime related to environmental exposure, equipment maintenance and repair, or both.
