The PowerTrac® PRIME is inherently designed to provide optimized
tractor conveyance in highly deviated wells for a wide range of
payload types, wellbore dimension and trajectory environments,
resulting in up to three times increased conveyance speeds. The
modular design allows the user to select and operate featuresthat are optimum to well conditions and operational needs.
A high degree of instrumentation coupled with advances inmechanical, hydraulic, and electronic componentry, as well assoftware, analytics and visualization, allows real time adjustment
and control of tool performance (speed, force) to optimize for theconditions encountered while in the well.
When combined with a Direct Drive Rotation device formechanical rotational services such as component milling or
wellbore cleanout, the tractor provides the rotational anchor inboth free-wheeling (rolling) or tractor driven mode, for hi-fidelity
control of weight on bit (WOB). WOB is synchronized along withrotational torque and RPM to optimize the rate of penetration(ROP) throughout the task, with the anchor mode switching on
the fly for uninterrupted back reaming capability.

PRIME Release Sub System

To enable controlled release of stuck toolstrings
Applications• Logging toolstrings in cased andopen hole• Tractor conveyance and Powered
Mechanical Applications

Features and Benefits• Release energized through wirelineor battery

PRIME Release Sub System – The Release Sub System (RSS) has beendeveloped to enable controlled release of stuck toolstrings. Multiple RSS’s canbe utilized, placed at the top of the toolstring or at relevant positions along
its length enabling partial retrieval. The PRIME RSS has integrated PRIME nodeelectronics, enabling full PRIME communication and in-well functionality
to PRIME tools positioned below, and in-hole configurability for releaseparameters. 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.

• Extended battery life
• High torque design enabling usage
with milling applications• Real time in-well configuration toadapt for changes in work scope• Can release even if cable isdamaged• 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 releasebakerhughes.com

PRIME Logging while Tractoring – Logging while Tractoring (LwT) functionality is available when passenger tool dataacquisition is required during conveyance in a highly deviated well. Examples of this are for a down log pass of a Production
Logging Tool (PLT) or Wellbore Camera. To achieve this an LwT sub is added to the PowerTrac® PRIME Toolstring.
The LwT can be run either in Conveyance mode - providing full PRIME Tractor communication and in-well functionality, or in
LwT mode – enabling two-way communication for third party passenger tools while tractoring, with mode selection done
in-well.
For passengers tools that require a lower operating voltage, a Customer Power Converter (CPC) is added. This provides a
stepped down voltage for passenger tool operation while maintaining maximum tractor performance and full passenger
tool telemetry.
