Reference guide summarizing key downhole configurations used with jet pump artificial lift systems.
Fixed Jet Pump Configuration
A fixed jet pump is set inside the well using a packer and seating assembly. The nozzle, throat and diffuser remain in place until retrieved by pulling the tubing.
When Used:
- Wells requiring secure placement with defined intake depth
- Environments with consistent reservoir performance
- Installations where tubing pulls are acceptable
Key Features:
- Stable geometry and predictable inflow
- Compatible with sliding sleeves for selective circulation
- Suitable for most vertical and moderately deviated wells
Free-Style Jet Pump (Retrievable)
A free-style jet pump can be deployed or retrieved through the tubing without pulling the completion.
When Used:
- Rigless deployment
- Wells with changing drawdown requirements
- Frequent adjustments to nozzle or throat size
Key Features:
- Rapid installation and retrieval
- Ability to adapt to production decline or IPR changes
- Useful during early-time well evaluation
Coiled Tubing Jet Pump
A compact jet pump conveyed on coiled tubing for rapid deployment.
When Used:
- High-angle or horizontal wells
- Temporary lift needs or well testing
- Minimal footprint operations
Key Features:
- Continuous circulation possible
- Faster mobilization than jointed tubing
- Effective for short-term flowback
Hybrid Jet Pump Arrangements
Jet pumps paired with other lift mechanisms for unique constraints.
Examples:
- Jet pump below an electrical submersible motor
- Jet pump used temporarily until mechanical lift is available
Key Features:
- Flexibility during equipment transitions
- Ability to maintain production under limiting well conditions
