ADJUSTABLE BACK
PRESSURE VALVE
The adjustable Back Pressure Valve is
used to hold pressure from above until
a pre-set internal pressure is applied to
the tool. Once the pre determined internal
pressure is applied a valve opens providing
communication through the bore of the
tool. This is useful where formation
pressure will not support a column of fluid
or as a safety tool for running pressure
activated perforating guns. The tool can be
used to provide a hydraulic advantage to
straighten tubing while running into a
deviated well by helping to prevent helical
buckling. The tool is fully adjustable to
open at settings ranging from 500 to 5000
psi and is easily field dressed.

HYDRAULIC TUBING END LOCATOR
The Hydraulic Tubing End Locator is
designed to allow accurate measurement of
the end of the production tubing shoe for
depth correlation. The tool is flow activated
to allow the operator to re-tag the end of the
tubing an unlimited number of times without
tripping to surface to re-set the tool. The
internal pressure generated inside the tool
forces the locator blades out of the tool body
to tag the end of the tubing. Being flow
activated allows the operator to vary the
amount of pump out force the locator blades
exert on the tubing by varying the flow rate.

ROTATING KNUCKLE JOINT
The CT Knuckle Joint provides a heavy duty
flexible joint in a tool string. Threaded
connections top and bottom let this tool
be placed anywhere in a tool string.
The knuckle is sealed metal to metal and
the body housings are sealed by o-ring.
The tool incorporates a thru bore to allow
flow for fishing or completion operations.
The knuckle joint will deflect through 6°
of angular movement in any direction.
FEATURES:
•
Flexible joint for deviated or
horizontal wells.
•
Flow through bore.
•
Easy field servicing.
Specifications subject to change without notice
TORQUE/FLOW THRU
KNUCKLE JOINT
The Torque/Flow Thru Knuckle
Joint when incorporated into the
tool string allows for a full 15° of
angular movement in all directions.
The tool will transmit torque and
incorporates a through bore to
allow circulation through the tool.
BOW SPRING CENTRALIZER
The CT Bow Spring Centralizer guides the coiled tubing or tool
string directly in the center of the well bore. It overcomes
the natural bend in the coiled tubing and prevents hang ups
when approaching restrictions. It can be run in logging or wireline
tool strings or with any other completion or production equipment.
FEATURES:
• Spring loaded bows
set for optimum
contact force with
casing or tubing.
• Bore through centralizer
for circulating flow.
• Hardened bows for minimal wear.
• Wide variety of thread sizes.
HYDRAULIC BOW SPRING CENTRALIZER
The Hydraulic Bow Spring Centralizer utilizes hydraulically expand-
able bow springs. In a static condition, the bow springs remain in
the retracted state, flush with the tools O.D. Circulating differential
pressure across the tool expands the bow springs to contact the
side wall of the well bore. Being hydraulically activated allows the
tool to generate sufficient force in deviated or horizontal well bores
to lift the tool string off the side wall, centering it in the well bore.
The tool is ideally suited to be utilized as a stabilizer with a down-
hole motor.
