PRIME Manipulation
Part of the PRIME digital electro-hydraulic intervention technology platform.
The PRIME Stroker is the latest component of Altus Intervention’s new PRIME Technology Platform. Designed for completion manipulation, it incorporates a high degree of instrumentation and multiple sensors providing tool and task parameter intelligence and control along with high-speed telemetry comms for real-time tool task management. The stroker anchors in the casing/tubing and applies bi-directional axial force to the manipulation tool to install, retrieve and manipulate completion components. It is run standalone in vertical wells or in combination with the PowerTrac® Tractor for conveyance in deviated wells.
Built on the PRIME 21/2” OD tool size architecture, the PRIME Stroker comes with an associated extended reach hydraulic shifting tool (XR-HST). This enables passage of the toolstring through small wellbore restrictions when the anchor and shifting tool are retracted, while being able to anchor and engage in larger tubing, sleeve or valve profile dimensions when activated.
Operation and control of the PRIME Tractor, Stroker and XR-HST functions can be done independently and simultaneously, enabling seamless multi-task operations. This is particularly important in highly deviated or horizontal wells. An example sequence could be: activating the shifting tool once at task depth and tractoring down to engage the shifting dogs within the target completion component profile ( i.e. in search mode), obtaining positive engagement of the shifting dogs in the profile using the tractor force and verifying this through tool tension measurements, setting the Stroker anchors while maintaining this force then switching the tractor to free rolling mode with arms open to maintain string centralization, and finally commencing the high force stroke in or out sequence to manipulate the targeted completion component.

PRIME RELEASE SUBS SYSTEM
The Release Sub System (RSS) has been developed to enable controlled release of stuck toolstrings. Multiple RSS’s can be utilized, placed at the top of the toolstring or at relevant positions along its length enabling partial retrieval. The PRIME RSS has integrated PRIME node electronics, enabling full PRIME communication and in-well functionality to PRIME tools positioned below, and in-hole configurability for release parameters. It also provides real-time release status based on sensor reading and battery life measurement.
RSS release is activated by telemetry commands, voltage variation or memory timer mode, enabling controlled release even with damaged cable.
Applications
- Logging toolstrings in cased and open hole
- Tractor conveyance and Powered Mechanical Applications
Features
- Release energized through wireline or battery
- Extended battery life
- High torque design enabling usage with milling applications
- Real-time in-well configuration to adapt for changes in work scope
Benefits
- Can release even if cable is damaged
- QHSE; reduces personnel exposure to cable breakage at surface due to high overpull
- Improved operational efficiency; less runs, increased measurements per run
- More efficient retrieval/fishing due to clean fishing neck after release
