PrecisionStroker
Manipulate and control your well
The PrecisionStroker is the primary tool in the Completion Manipulation service portfolio. It anchors in the casing/tubing and applies bi-directional axial forces to the appropriate manipulation tool to install, retrieve and manipulate completion components. The Hi-Strength option is designed specifically to support fishing operations or for manipulation of completion components that are not shifting as per their specified force.
Applications
- Valve manipulation (gas lift valves, sliding sleeves, formation isolation valves)
- Retrievable bridge plug pulling
- Other linear actuating applications (stackable straddles, breaking ceramic discs, etc.)
- The Hi-Strength option provides a high force level necessary to target the recovery of stuck tools, re-enabling lost wellbore access
Key Features
- E-Line conveyed, powered device
- Unlimited number of strokes cycles
- Mechanism ensures stroke position is maintained even after powerdown
- Real-time monitoring and control of applied force and positioning
- Bi-directional stroke with positioning system resolution of +/- 0.04inches/1mm
- Pad anchoring device provides even and reduced pressure on tubing
- Progressive anchoring force proportional to magnitude of push/pull on completion component
- Extra high pulling force option for fishing operations
Benefits
- Run standalone in vertical wells and combinable with PowerTrac® for conveyance in higher deviations
- Ideal for precision shifting procedures, due to downhole stroke force and position control (+/- 1mm)
- Superior manoeuvrability due to independent anchor control
- High operational efficiency; due to unlimited number of strokes per run in the well and electrical feed through, allowing e-Line tools to confirm in real-time the impact of component manoeuvre
- The Hi-Strength option provides increased mission target certainty during fishing applications due to its high force capability combined with its real-time monitoring and control of applied force and positioning and unlimited number of strokes
