Ideal for all fluid transfer operations, the HPS system is engineered to match flow rate and pressure requirements. It is equipped with real-time remote monitoring to support safety shutdowns/alarms according to all regulatory requirements when connected to existing control systems.

Hydraulic jet pump (HJP) artificial lift solution

We offer operators artificial lift solutions from flow back through production with a unique horizontal pumping system (HPS) and versatile hydraulic jet pumps (HJP) that provide advantages over rod lift and ESP systems in many environments.

Our goal is to lift higher volumes and reduce operating costs by eliminating the common issues of artificial lift gas locking and solids handling, maintaining production over a wide range of rates and reducing well intervention and maintenance downtime.

For artificial lift operations, our solution combines a unique horizontal pumping system (HPS) with a versatile hydraulic jet pump (HJP) to provide many advantages over conventional artificial lift systems:

  • Lower operating costs leading to reduced LOE
  • Less maintenance with minimal downtime (98% to 100% run time)
  • Highly mobile with a unique trailer-mounted system
  • An efficient filtration system that prevents impurities from entering the pump and wellbore.
  • Usage of a versatile downhole jet pump in conjunction with a gas lift and many completion scenarios (conventional, reverse circulation, and concentric).

The Flex Flow System has a successful track record

2018 case study shows how the Flex Flow System can add to the bottom line


An operator in Andrews, Texas, wanted a high-flow solution that would maximize well profitability.

Well specifications

  • Casing   5 1/2 inches
  • Tubing   2 7/8 inches
  • TVD       6,680 ft

Equipment specifications

  • Free-style standard-flow jet pump with an E:11 throat and nozzle
  • 300-hp surface pumping unit


The Flex Flow system, comprising a horizontal pumping system (HPS) and a hydraulic jet pump (HJP), proved to be a highly profitable artificial lift method. The incremental lifting cost was $24,000 or $11/bbl per month. With a net oil price of $45 and total monthly production of 2,088 bbl, the incremental monthly operating cash flow was $70,992.

2018 case study shows how the Flex Flow System can reduce OPEX/Interventions


In Andrews, Texas, an operator was plagued by high sand cut (1% to 3%), which caused a high failure rate in a well completed with an electrical submersible pump (ESP). The well was reconfigured to rod lift but failed 37 days after wearing out 115 tubing joints. The Flex Flow system was installed to reduce OPEX and the frequency of interventions.

Well specifications

  • Casing   5 1/2 inches
  • Tubing   2 7/8 inches
  • TVD       9,500 ft


The Flex Flow horizontal pumping system (HPS) and hydraulic jet pump (HJP) extended run life from ~38 days to 185 days, reducing OPEX/month by more than $25,000. Eliminating six interventions per year saved hundreds of thousands of dollars.

2018 case study shows how the Flex Flow System can achieve faster Frac flowback


An operator in Andrews, Texas, allowed Flex Flow to compare the performance of an electrical submersible pump (ESP) with a Flex Flow system comprising a horizontal pumping system (HPS) and a hydraulic jet pump (HJP). The test was run in two adjacent and similar wells after hydraulic fracturing and flowback. Well 1 was lifted with a Flex Flow system, and Well 2 was placed on an ESP.

Well specifications

  • Casing   5 1/2 inches
  • Tubing   2 7/8 inches
  • TVD       10,000 ft


The Flex Flow system consistently lifted higher volumes than the ESP during the first year of production. In addition, the Flex Flow system has a lower upfront cost than the ESP, making it the best choice for dewatering the well.
