Thru-Tubing Intervention tools and specialized systems

Nordic / Red Adair has a specialized thru tubing intervention division whom are experts in custom made solutions to solve any down-hole problem in oil, gas, water and salt wells, and complete project engineering.

Our strength is our flexibility to respond customer needs, and to design tools suitable for any specific problem.

Nordic / Red Adair design, manufacture and supply well bore tools for the Oil and Gas Industry to provide our customers with efficient, reliable quality products and offer first class performance. The tools are designed to be more than fit for purpose by being easily re-dressed in the field, simple to operate and having extended tool longevity.

Nordic / Red Adair has a wide range of tools available 24/7 in our Dubai workshop. Our field engineers have many years of experience, which gives them the ability to rapidly, create an imaginary picture of the down-hole problem and come up with the best solution.

Thru-Tubing intervention is increasingly used to service highly deviated, extended reach and horizontal wells which have become the typical well design in today's field development. Nordic / Red Adair has developed tools and systems to perform advanced and cost effective thru-tubing intervention operations.

The following operations are typical for coiled tubing or jointed pipe, but by no means limited to: logging, perforating, setting and retrieving plugs, opening and closing sliding sleeve, fishing, removing scale and debris, re-entry drilling, matrix acidizing and acid washing.

Thru-Tubing Intervention Tools

Coiled Tubing Connectors

The connector provides a way for attaching tools to the Coiled Tubing (CT). Nordic / Red Adair can offer a range of proprietary and 3rd party supplied connectors for any operation. These are typically attached either by Slip Mechanism, Internal or External 'Dimpling' procedure, Roll-on or Quad Pin.

Standard Bottom Hole Assembly (BHA)

A standard BHA would consist of the Connector, Dual Flapper Check Valve, Emergency Disconnect & a Dual Circulation Sub, which gives you the basic well control components, as well as the ability to get out of a stuck situation.

Motor Head Assembly (MHA)

Originally the MHA was developed for Coiled Tubing Drilling Operations, so that the components of the Standard MHA could be fitted into one tool, shortening the tool string considerably. Today the MHA is the preferred tool in any CT operation, over individual components, as they are too cumbersome and take up too much of a deployment length.

Dual Flapper Check Valve (DFCV)

DFCV is the industry preferred well control means, but there are other types such as ball, dart and a combination of the two.

Drop Ball Hydraulic Disconnect.

The standard disconnect tool of the industry, whereby pins are sheared when applying pressure to a ball pumped through the CT and landing on a seat in the BHA/MHA, shear pressure is adjustable. This allows a safe means of disconnecting from a stuck tool string below the Disconnect, and leaves a standard Internal GS Fish neck in place for later fishing operations.

Emergency Pull Disconnect.

A tool that can be released just by applying a predetermined Over pull to the CT, thus shearing a set of pins in the tool. This could be used in operations where inserting a ball in CT is impossible, as when Wire line is used in the CT.

Flow Release Disconnect

Another tool developed to disconnect without the use of a drop ball. The tool is fully pressure balanced and activated by flow, not pressure. A secondary set of pins also has to be sheared by Over pull, to avoid premature release.

Heavy Duty Disconnect

A heavy-duty drop ball disconnect developed for CT Drilling, Jarring and other high load operations.

Dual Activated Circulation Sub

A sub that incorporates two sets of circulation ports. Dropping a ball activates one, and shearing pins by applying pressure to the ball on seat. Applying pressure to the CT to burst a preset disc activates the other port. This allows circulation even though the toolstring might be plugged up below the sub. It can also be used to increase annular velocity or reducing wear on a PDM upon completion of an operation.

Fishing Tools

Hydraulic Release Overshot

This is a heavy-duty flow release tool for CT or Jointed Pipe (JP) operations. It is specially designed to catch a variety of standard external fishnecks, and by changing out the bowl & grapple it can easily be converted to a slick OD catch tool.

Hydraulic Release Spear

This is a heavy-duty flow release tool for CT or JP operations. It is specially designed to catch a variety of standard internal fishnecks, and by changing out the bowl & grapple it can easily be converted to a slick ID catch tool.

Snipper Cutting Overshot.

Snipper is a tool by Thru-Tubing Technology specially designed to wash over and catch stuck CT in the well. By applying Overpull to the tool, the 'grapples' lodge & cut the CT at the desired depth. The Snipper Overshot can be run with a High Pressure Pack-Off, described later.

Continuous CT Overshot

Basically the same as a Snipper, although equipped with regular gripping grapples that will not necessarily cut the CT, and can also be run with a Pack-Off.

High Pressure Pack-Off

This is designed to be run either with the Snipper or Continuous CT Overshot, to provide a pressure tight seal around the CT to be brought out of the well.

Thru-Tubing Motors & Rotational Tools

Tubing Cutting BHA

This BHA combines Hydro-Mechanical anchor, PDM motor and a Hydro-Mechanical Tubing Cutter.

Coiled Tubing Drilling Motors.

Nordic / Red Adair's PDMs are considered to be some of the most powerful PDMs in the industry, and just as important, most reliable. They come in sizes from 1-11/16"OD to 3- 1/2"OD with 2-?", 2-?" & "2-?" OD completing the line-up. The PDMs has been run successfully in a variety of heavy duty milling operations, extensively in CT Drilling operations including all window milling aspects, tubing cutting, under reaming and plug removal operations.

PDC Mill

The Full Body PDC Mills are ideal for drilling cement & hard scale as Strontium & Barium Sulfate. Carbide Buttons range in size from 5/16" to 1/2". Bit Size Range: 1-3/4" to 6-3/4" in ?" increments. Circulation ports available from 5/16" for downhole motors to 1" for reverse circulation. Custom sizes also available.

Insert Step Mill

This mill was primarily designed for the removal of nipple profiles in tubulars. It has been used successfully on scale removal and opening up the ID of tubulars blocked by scale etc. Can be custom made to any size wanted.

Junk Mill

Typical Tungsten Carbide impregnated Junk Mill. Can be Convex, Flat, Concave or Tapered to suit any eventuality.

Bladed Junk Mill.

Tree or four bladed Junk Mill, very aggressive and with Tungsten Carbide inserts to ensure removal of virtually any obstruction in the well.

Two-Step Underreamer w/Pilot Mill

This multi-faceted tool has the ability of cleaning tubing, casing, drill pipe, liners or even open hole. Hydraulically actuated blades allow the capability of running through small diameter restrictions and cleaning out larger inside diameters. Tools range in size from 1.7"OD with a capability of full wall cleaning to 3.5"ID, to the 5.25"OD tool capable of a full wall clean out up to an 11"ID. Self-centralizing by 90o offset blades in two stages eliminates the need for a centralizer. A mill or a bit is run as a pilot on the tool, and circulation is established completely through the bit, effectively cleaning and cooling both the bit and the blades.

Internal Hydro-Mechanical Tubing Cutter.

The Nordic / Red Adair Internal Hydraulic Tubing Cutter is a pressure activated internal cutting tool designed to cut pipe and tubing. The tool comes in various sizes with a range of blade materials and inserts technologies to meet the most demanding of applications. Will cut from 2-?"-5-1/2"OD Drill-pipe, Tubing, Casing or Liner.

It is a result of an extensive testing program, which optimized the blade geometry and cutter configuration.

Internal Rotational Hydro-Mechanical Anchor

The Tubing Anchor is used to fix the tubing cutter assembly in a position in the well bore so that no axial movement can take place and provides a platform to isolate axial forces and vibrations caused by the PDM from the tubing cutter.

The grip for the anchor is provided initially by a collet expanding when forced with a hydraulic piston against a cone. When additional forces are applied these add to the setting force and grip of the anchor. The anchor is reversible so that it can take forces from above as well as below.

Thru-Tubing Impact & Fishing Tools

Up & Down stroke Hydraulic Accelerator

The accelerator is an energy accumulator used in conjunction with the Up or Down stroke Hydraulic Jars to maximize the impact delivered to the stuck point.

Up & Down stroke Hydraulic Jars

The Dual-Acting Coiled Tubing Jar meets the needs of the CT industry; with it's small outside diameter CT Drillers get the quality and performance of a conventional drilling jar. Comes in sizes from 1-3/4" -2-1/4"OD.

Thru-Tubing Clean-out tools

Spherical Jet Nozzle

The spherical jet nozzle is a unique clean out nozzle with a constant 360 degree jetting circumference for complete coverage of the wellbore. The jetting direction can be preset to either down stream or up stream jetting tailor making the nozzle to a specific well need. The spherical jet nozzle can be configured in a number of different ways for maximum efficiency.

Sand Catcher Venturi Bailer

The Nordic / Red Adair's Sand Catcher bailer is a flow operated tool that creates a strong vacuum that draws fluid and debris into the bailer. A high performance filter allows the fluid to pass through to the annulus but traps the debris between the flapper valves at the bottom of the bailer section and the filter at the top of the bailer section. Can be run on coiled tubing or jointed pipe and with or without a PDM. The nozzle design and proprietary sand filter allow the Nordic / Red Adair Sand bailer to outperform conventional sand removal systems.

Debris Catcher

The Debris Catcher is run above the PDM to help catch any debris from the well during a milling operation.
