How the Hydraulic Jet Pump (HJP) Works

At the heart of the HJP are its nozzle, throat and diffuser. Fluid is directed into the nozzle at high speeds, generating a pressure difference. This kinetic energy, produced as fluid exits the nozzle, aids in drawing more fluid into the diffuser, converting it to a high-pressure state. Given these capabilities, Flex Flow's jet pump is a preferable choice in challenging oilfield scenarios over traditional lift systems.

Select Component Breakdown

Key components of this hydraulic jet pump include:

• Bottom hole assembly (BHA)
• Housing J-Tube
• Standing valve
• Carrier

Depending on the depth, the expected downtime is +/- 1 hr for intervention.

The jet pump is deployed by connecting it to the BHA and dropping it down the hole. The housing and carrier will sit at the bottom with metal-to-metal contact. If you need to retrieve the carrier, you can do so by reversing flow rates to the annulus.

This will enable the carrier to pass through the tubing string and be isolated by shutting the master valve. After any inspection or replacement of throats and nozzles, the carrier can be dropped from the surface and production will resume.

Required Surface Equipment

• A horizontal pumping system is used to provide needed power fluid to the jet pump nozzle to create the venturi effect.
• Holding tanks for power fluid. Additional tanks can be used to set for well production as an independent battery.
• Three-phase separator separates power fluid from the produced fluid, allowing production to be sent to central battery.
