Small-diameter ESP wells often force a compromise between horsepower and space. The Affirmed PowerFit™ ESP small-diameter motor eliminates that tradeoff by delivering the horsepower you need in a compact 4.20-in. OD design—without motor modifications or complex configurations.
Applications
- Unconventional and conventional oil wells
- Wells completed with 5½-in., 23 lb casing
- Wells completed with 5½-in., 20 lb casing that require a:
- Chemical injection line
- Sensor with discharge pressure
- Modification to 4.56-in. motors
Benefits
- Eliminate modifications necessary with 4.56-in. motors
- Prevents erosion from sand entrained in the fluid stream
- Reduces the risk of getting the ESP stuck in the well
- Provides space for a chemical injection line
- Facilitates the use of a downhole sensor with discharge pressure
- Eliminates risks associated with triple-tandem motors
- Simplifies operations by using standard induction motor surface control systems
- Requires no special HSE, installation, or operating procedures
Features
- Motor OD: 4.20 in [106.68 mm]
- Optimized electromagnetic motor design to deliver 208 HP per motor while operating at temperatures up to 204 °C (400 °F)
- Built-in reliability enhancements:
- Polymer-coated tilt-pad thrust bearing for high-load conditions
- Increased polyimide insulation for improved electrical integrity
- Outboard rotor bearings to reduce vibration
- Shaped rotor bars to minimize electrical losses and heat generation
