Product Description

COILED TUBING TOOLS

DOWN-STROKE HYDRAULIC JAR 
The Down-Stroke Hydraulic Jar (DSHJ) provides the means for repeatable, controlled downward jarring when required during coiled tubing operations.
The 'DSHJ' has a highly dependable closed and balanced hydraulic system for hydrostatic pressure. This allows the coiled tubing operator to control the intensity of the jarring action to suit the field application, by applying a sustained downward load, which can be infinitely variable, according to the usage application.
The 'DSHJ' is normally used in conjunction with the CT Down-Stroke Intensifier. It is suitable for most coiled tubing applications where the deployment of downhole service and manipulation tools is required, including setting and pulling plugs, gas lift valves, opening and shutting sliding side doors and the general fishing of downhole retrievables.
The 'DSHJ' is also used in most standard coiled tubing tool strings during other coiled tubing services such as swabbing, jetting, logging, and stimulating, especially in deviated wells, where there is a possibility of the tool string becoming stuck. The closed hydraulic system prevents contamination from well bore fluids thus giving greater operational dependability. Under normal conditions the 'DSHJ' will function at temperatures of up to 100°C if circulation is maintained during operations. The 'DSHJ' is manufactured from high grade low alloy steel and stainless steel and is extremely robust and durable in construction.
Design Features/Benefits:

• Full flow through bore
• Specifically designed for CT use
• Efficient Valve Seating for deviated applications
• Closed & balanced hydraulic system
• Also available with 'Torque Thru' capability

ROTO-HAMMER IMPACT DRILL JAR
The Roto-Hammer is a tool that transmits multiple downward impact forces at high frequency when fluid is pumped through it, thus eliminating the need to cycle the coil. The tool operates through a combination of layoff weight and controlled flow activation through the tool-string, converting flow and pressure into mechanical energy.
Applications:

• Under balanced & over balanced clean outs
• Shifting stubborn sliding sleeves
• Breaking ceramic & glass discs
• Swaging collapsed tubing & screens
• Broaching operations
• Driving debris downhole
• Scale clean out including: cement, resin coated sand, plastic, barium, calcium & iron

HYDRAULIC UP/DOWN JARS
The Hydraulic Up/Down Jars use a piston (metering device) and oil to create a time delay. This time delay allows energy to be stored in stretched tubing. Once the energy is stored, the jar piston bypasses (step), creating a hammer-and-anvil effect that imparts an impact load to the end of the tool assembly. As the jar is pulled in tension, a piston moves through a restricted bore containing oil. This process enables the system to store energy and the continued upward pull moves the piston over the step, which releases the stored energy and allows the mass to rapidly accelerate to the top of its stroke. This process creates an impact force that can be twice as great as the tension that can be pulled on the tubing alone. The force supplied depends upon the force applied at the tool. The Hydraulic Up/ Down Jars can be supplied either up acting, down acting or bi-directional.
Design Features/Benefits:

• Jar is shorter than most hydraulic jars
• Higher impact capability, it can hit harder than any other jar of the same size
• Maximum operating temperature 500 degrees F
• Large bore for drop ball
• Jar has high tensile strength for higher impact service capability
• Jar is hydrostatic pressure balanced
• Jar can be run in compression or tension

• Jar can be run in compression or tension

HYDRAULIC UP/DOWN INTENSIFIERS
The Hydraulic Up/Down Intensifiers is a double acting accelerator used to increase the impact effect of the Hydraulic Up/Down Jars. The Intensifiers stores concentrated energy in an optimal position in the Jar string. It helps to absorb impact shock waves that travel up the drill pipe allowing the drill string to be utilized closer to their yield loads. This permits higher pull loads to be placed on the hydraulic drilling jars. The Intensifiers provides the operator the ability to perform impact operation at or near the surface. The compressibility provides the necessary "stretch" to operate the Jarring equipment. The Intensifiers supplies drive for the concentrated weights in the jars string in the same manner as the long resilient drill string. It is an efficient reservoir for storing energy since its stretch is confined to a short tool length. The increased efficiency and stretch provides a much harder hitting Jar system and increases the impact up to approximately a factor of three and can impact at much higher impacts depending on conditions. It will work on any drill string and provides a means to get higher impact load in a crooked or extended reach well, where drag is a significant factor. The Intensifiers /Jar system should be placed as close to the stuck point as possible. The impact effect diminishes as the distance increases between the intensifiers and the Jar and the stuck point.

Design Features/Benefits:

• Higher intensifiers capability, it can hit harder than any other jar/ Intensifiers of the same size
• Maximum operating temperature 500 degrees F
• Large bore for drop ball
• Intensifiers has high tensile strength for higher impact service capability
• Intensifiers can be run in compression or tension.

BOW SPRING CENTERALIZER
The Bow Spring Centralizer provides a fast and effective method of attaching centralizers to a tool string. This approach allows several centralizers to be attached to a coiled tubing tool string without adding any significant length to the string.
By simply positioning the Centralizer Carrier Subs in the tool string, the Bow Spring Centralizers can be placed in the optimum position to centralize the string.
The tool is specifically designed to allow worn or damaged bowsprings to be changed without removing the whole centralizer assembly. Also, the centralizer assemblies can be removed without breaking out the string.
The upper centralizer sleeve is anchored to the tool string via retainer pins. The lower centralizer sleeve is allowed to ride freely up and down the tool string as the bowsprings compress and expand. This ensures the minimum of interference as the tool string passes through restrictions in the tubing.

FLOW ACTIVATED BOW SPRING CENTRALIZER
The Flow Activated Bow Spring Centralizer is designed to allow tool strings or parts of tool strings to be centralized in the tubing/casing for various operations.
The Flow Activated Bow Spring Centralizer is designed so that it's bow springs are normally retracted. The bow springs only expand when a pressure differential is achieved across the tool. This enables the centralizer to pass, for example, through the restricted bores of the tail pipe and expand into the casing liner below without any unnecessary wear on the bow springs.
As a safety precaution, the bow springs are mounted above a coil spring. This is to allow the bow springs the necessary movement they require in order to pass through a restricted bore whilst still expanded.
Design Features/Benefits:

• Full flow through bore
• Safety feature which allows bow springs movement when meeting restrictions in expanded condition, therefore preventing bow spring damage

TORQUE THRU KNUCKLE JOINT
The Torque Thru Knuckle Joint, when incorporated between the jars and the manipulation tool, will provide additional flexibility in the tool string. This additional flexibility is often necessary when the bore of the hole the tool is running through is restricted and/or highly deviated. The Torque Thru Knuckle Joint can be used when rotation of the tool string is not required, for example, coiled tubing drilling applications.
The Coiled Tubing Knuckle Joint provides full 15° angular deviation and internal pressure sealing throughout the full deviation of the tool. The ball and socket of the knuckle have a key that prevents rotation but still allows full angular movement.
The full flow through bore also allows the use of flow activated tools below the Knuckle Joint. Multiple coiled tubing torque thru knuckle joints can be incorporated in particularly long tool strings.
Design Features/Benefits:

• Full flow through bore
• Internal pressure seal
• 15° angular deviation
• Torque Thru capacity

SWIVEL JOINT
The Swivel Joint is a standard tool string component which when used, permits full rotation of the BHA made up below the joint.
The Swivel's design includes integral sealed bearings which ensure full integrity of flow through the joint.
The inclusion of a Swivel Joint in a typical BHA gives the operator orientation flexibility. A CT Swivel Joint in a BHA will allow the tool string to be broken and made-up below the joint without the need to disconnect from the coil.
The Swivel Joint is necesary where tool sting orientation is required such as in the running and pulling of gas lift mandrels.
Design Features/Benefits:

• Full range of sizes available
• Sealed bearings for integrity of flow
• Maximum flow area
