PrecisionExpander 318
The PrecisionExpander 318 is designed to repair damaged completion components e.g. DHSV flow tubes, mule shoes and slightly collapsed production tubing, thus re-enabling component functionality and/or wellbore access.
It is run in combination with the PrecisionStroker, converting the stroker axial position and force to a radial position and force.
Applications
- Expansion of collapsed TR-DSHV flow tubes
- Repair of damaged mule shoe
- Repair of slightly collapsed/dented production tubing
Features
- E-Line deployed/powered device with real-time measurement and control
- Stroker axial force amplified to a high radial force (circa 4x)
- No axial force applied onto damaged area
- Precise control of expansion OD (0.1 mm resolution)
- Unlimited expansion cycles
- Inherent fail safe functionality
- Immediate drift verification capability
Benefits
- In-well repair solution, minimising time, cost and risk exposure
- Precise, light on logistics, footprint and personnel
