PRODUCE RESERVOIRS WITH UP TO 85% GAS AND EXTEND THE ECONOMIC LIFE OF LOW-FLOW WELLS
 

HIGH-GAS OPEN-STAGE ESP SYSTEM

The high-gas open-stage ESP system uses an open impeller design (with no upper or lower disk) to produce low-flow, gassy wells. The open-stage ESP is lighter and smaller than other electrical submersible pumping (ESP) systems, provides better gas handling capabilities, and helps mitigate scale deposition.

BENEFITS

Produce reservoirs with up to 85% free gas


Open impeller design handles high gas volumes and reduces scale deposition
Extend the economic life of aging, low-flow wells


Low-flow ESP technology performs in rates ranging from 63–10,064 bbl/d
Eliminate rod-lift wear and maintenance

Bottom-drive ESPs eliminate rod damage to the production tubing and required rod-lift maintenance



applications

  • Conventional and unconventional wells
  • High-gas, high-solids reservoirs complicated by scaling and variable inflow

capabilities

  • Gas content up to 85%
  • Flowrate ranges from 63–10,064 bbl/d (10–1600 m3/d)
  • Available in 362 (92 mm),
    406 (103 mm), 449 (114 mm), and 535 (136 mm) series

features

  • Open impeller design handles gas, reduces pump weight, and reduces vibration
  • Elimination of upper and lower impeller disks mitigates clogging caused by scale and solids

Gas locking and pump seizure in ESPs occur when gas fills flow channels and effectively blocks fluid from passing through the system. The high-gas open-stage ESP omits the upper and lower disks from the impellers, eliminating the cavities in which gas can get trapped. So gas is dispersed into the reservoir fluid along with any existing solids to create a homogenized gas-fluid-solid mix that can pass through the pump.

Compared to common submersible pumps, the open-stage ESP is lighter and shorter, improves gas handling capabilities, and reduces scaling. It is ideal for use in low-flow, sandy, high-gas wells with variable flow rates.

With consistent performance at low flow rates, the open-stage ESP is a good candidate for replacing many rod-lift pumps, which are notorious for wearing through tubing and require regular workovers and maintenance operations.
