PRIME Compact SeriesPart of the PRIME digital electro-hydraulicintervention technology platform
Applications• Tractor deployment on rigs withrestricted rig up height• Deployment optimization for long
toolstring payloads- Long interval perforation
operations

Features and Benefits• PRIME instrumentation andmultiple sensors providing tooland task parameter intelligence• An open IOT architecture andhigh-speed telemetry supporting
real-time communication for tool
task management• Dynamic, in-well optimization ofspeed, force, torque and power
delivery across the tractor andapplication tools:

PRIME Compact TractorThe PRIME Compact Tractor brings PRIME capabilities to a 3-3/8"
OD Tractor architecture. This while utilizing the high degree of
instrumentation and advances that PRIME provides in regard
to mechanical, hydraulic, and electronic componentry, as well
as software, analytics and visualization. Real-time adjustment
and control to optimize tool performance for the conditions
encountered while in the well is fully maintained, with yet
additional features and benefits available on a shorter, sturdier
tool body dimension.
Higher power/speed tractoring is delivered from this compact
tractor, leveraging the increased tool OD to deliver a 4-wheel
drive section configuration of 3-3/8" wheels. This provides a
tractor length reduction of 33% when compared to a 2-1/2"
PRIME Tractor of comparable drive section configuration. This
enables access to deviated wells where rig up height is an issue
hampering tool string deployment.

- Downhole logic and toolcontrol- Highly efficient motor
controllers- Hydraulic steering• Modular and scalable versatility
for plug-and-play field
configurability, enabling tool
integration & combinability
for single run/multifunction
operations• Tension/Compression subs canbe added, both above and below
the Tractor• Integral field joint in top section
for extreme rig-up conditions e.g.
working in cellar decks• Enabler for limited rig up height
operations

PRIME Compact
Stroker/ Tractor
The PRIME Compact Series 3-3/8” OD tool architecture provides
benefits far beyond just a shorter tractor length. Integrated
combinability and control of other key powered mechanicalcomponentry is achieved, optimizing multi-function toolstringlengths.
In the case of the PRIME Compact Stroker/Tractor, thisbenefits intervention operations impacted by rig-up height
constraints. Executing stroker operations in deviated wells, bethat for completion manipulation work scope, or for plannedor precautionary fishing purposes, can now be achieved by atoolstring of overall shorter length.
