Tough Boy™ Debris Removal Tools
Tough Boy™ Waste Retriever
U.S. Patent #6951251B2
Description / Application
The Bilco Tough Boy™ waste retriever series are tools designed to capture well debris. The tools classified as riser waste retrievers have a large capacity basket capable of holding quantities to 14 US gal (2.2 ft3). This riser tool was designed in recognition that even at high pump rates only relatively low annular velocities are achieved in the riser. This design features screened drainage for positive debris removal, venturi jet porting to enhance debris capture through fluid manipulation and a robust solid mandrel design with 6 5/8-in reg. tool joint connections for superior torsion and tensile strength.
The Tough Boy™ Standard Waste Retriever is for instances where a waste retriever run will be done after circulation and mud conditioning to check for mud cleanliness.
In the dynamic environment of deepwater completions a higher degree of cleanliness is required to prevent non-productive down time. This tool will retrieve debris that has been loosened but not circulated out, which otherwise fall down the well bore to be a potential fouling problem.
The Bilco Tough Boy™ Waste Retriever is generally run above the Bilco Tough Boy™ Riser Brush Tool as an integrated approach to clean and validate well bore cleanliness. This tool combination is most effective when spaced above the lower marine riser package (LMRP), and is exposed to all circulation related to the clean-up and displacement operation.
The Tough Boy™ Standard Waste Retriever can be run in conjunction with a Tough Boy™ Brush below it it to assure tubing wall cleanliness or on a check run to provide assurance that the circulation operations have removed all potentially formation damaging debris.
The Tough Boy™ Riser Waste Retriever and Tough Boy™ Standard Waste Retriever can be run in all fluids. it becomes more effective as carrying capacities during fluid exchange operations decrease due to lower fluid densities.
Tough Boy™ Filter Tool
The Bilco Tough Boy™ Tools Filter Tool is designed to capture particulate matter that has been dislodged as a result of a successful wellbore clean-out operation. Run in conjunction with a variety of casing scrapers, brush tools, jetting tools and a flow check sub this filtering device will minimize debris falling back into the wellbore. The Tough Boy™ Filter Tool, jetting assembly and/or casing scraper or brush tool should be run in conjunction with the wear bushing retriever in a single run to save rig time and lower completion or work-over costs.
In operations to retrieve the wellhead wear bushing, the robust Bilco Tough Boy™ Tools Filter Tool should lead the clean-up retrieval assembly in the hole with a work string stand spaced between a flow check sub and well head jetting tool. The Bilco Tough Boy™ Wear Bushing Retriever should be spaced above the clean-up tools in the work string. As the wellhead wear bushing is retrieved the exact distance is pulled to place the Bilco Tough Boy™ Jetting Tool across the wellhead profile. The jetting operation will dislodge debris and clean the wellhead profile in preparation for the hanger assembly.
This clean up assembly with a scraper and/or brush tool instead of the jetting tool can be used to remove heavy debris created during a scraping or brushing operation in the casing that could settle on and foul completion equipment further down the well. Any loosened or suspended solids will be filtered through the screen mesh and retrieved when pulling the clean-up string out of the hole.

The photo at right shows the Bilco Tough Boy™ Magnet after a wellbore clean-up deployment.
The Tough Boy™ Magnet Tool should be run in combination with Bilco Tough Boy™ Scrapers and Brushes or as a stand-alone device in milling operations. The Tough Boy is available in various sizes to meet most drilling and completion requirements. A scraper/brush/ magnet combination should be spaced to reach the bottom of all casings and liners to meet each individual casing program. This tool combination will complement most completion operations. Bilco strongly recommend that all wiper rubbers be removed prior to pulling the Tough Boy™ Magnet Tool through the rotary. Magnetic storage devices such as credit cards, computers, and watches should be kept away from this tool due to its strong magnetic fields.
Tough Boy™ Combo Magnet Jet Tool for BOP's
U.S. Patent # 8,607,871 B2
This new tool allows you to jet the area above and below the wear bushing and retrieve any shavings or metallic debris on the magnets above jet nozzles. After cutting a window for sidetracking, shavings are left behind and may not get circulated out of the hole. They can now be forced out and trapped by magnets with this new combo tool.
The tool has a 10 inch OD with magnets below the tool joint with 7/8” jets that are spaced, 8 at 45 degree angles and 8 below that are horizontal. Below the horizontal jets, the 10” OD of the tool has a 45 degree bevel, allowing it to fit in the wear bushing fitted with 4 flutesso that circulation is not hampered. Below the flutes, the OD changes to 6 1/4”, 34” below that are two 5/8” jets at 45 degree angles, and 8” below those jets two more are horizontal jets.
Tough Boy™ Fluid Manipulation Tools
Tough Boy™ Riser Jet Tool
Bilco's Tough Boy™ Riser Jet Tool is a solid mandrel valve with a 16” OD for use in 18 ¾” or larger BOP’s and risers. It can be run in the clean-out/displacement string or can be introduced after short tripping the proper distance to tag the wellhead for depth control. This tool is used to hydro blast the BOP cavities, removing lodged solids/debris and introducing them into the fluid stream while increasing annular velocities in the marine riser. There are 18 .625” ID jet nozzles that direct fluid up, out, and down to thoroughly dislodge gunk and debris. The number of nozzles and direction of flow can be configured to accommodate surface equipment and hydraulic concerns.
When the tool is positioned at the wellhead and rates have been established through the bit the Tough Boy™ Riser Jet Tool is activated by dropping a retrievable dart and shifting the tool to the open position. This position directs all of the flow through the jetting nozzles. The tool is then rotated slowly and reciprocated the appropriate distance to cover the stack. At maximum achievable flow rate down work string plus maximum boost line rate the debris is introduced into the fluid stream and lifted into the riser. A Bilco Tough Boy™ Riser Waste Retriever is generally run a double (64’) above the jet tool to accomplish complete removal of the lifted solids. After the jetting operation the tool is deactivated by dropping a second retrievable dart, which redirects the flow down the work string, back to the bit. Fluid exchange operation can continue without the need for a designated trip to remove the jet and waste retriever tools.
Tough Boy™ ByPass Jet Tool
Bilco’s Tough Boy™ Jet Tools are a solid mandrel valve with a 6 3/4” OD for use in 9 5/8” and a 10 3/4" OD for 13 3/8"or larger casing. This valve can be run in the clean-out/displacement string to jet the wellhead or provide drill string to annulus communication as a By Pass/Circulating Sub. This tool is used to hydro blast the wellhead or BOP cavities removing lodged solids/debris and introducing them into the fluid stream while increasing annular velocities in the marine riser. The 6.75" OD has 4 jet nozzles that direct fluid out to thoroughly dislodge gunk and debris. Each nozzle has an ID of .625” with a total flow area of 1.483 square inches. The 10 3/4" OD has 12 jet nozzles with a total flow area of 4.440 square inches using jet nozzles with a .615" ID.
When tool is positioned at the well head and rates have been established through the bit the jet tool can be activated by dropping a steel ball and shifting the tool to the open position. This position directs all flow to the jetting nozzles. The tool is then rotated slowly and reciprocated the appropriate distance. At maximum achievable flow rate plus maximum boost line rate the debris is introduced into the fluid stream and lifted into the riser. A Bilco Tough Boy™ Waste Retriever is strategically placed above the jet tool to accomplish complete removal of the lifted solids. After the jetting operation the tool is deactivated by dropping a second steel ball, which redirects the flow down the work string back to the bit. Fluid exchange operation can continue without the need for a designated trip to remove the jet and waste retriever tools.
Tough Boy™ Wellhead Jet Tool with or without Bull Nose
Bilco’s Tough Boy™ Wellhead Jetting Tool is a simple, but effective, jetting tool designed to clean risers, BOP’s, wellheads and casing/tubing hanger areas. The tool is a one-piece body with threaded, replaceable jet nozzles. The nozzles (.5625” ID) are configured with eight pointing down and eight pointing out for maximum cleaning effectiveness. The nozzles are available with Carbide inserts if the job calls for more than 20 BPM. This robust tool is equipped with standard drill pipe connections for easy insertion into a clean-up or drilling string. Available with connections on both ends or a built-in Bull Nose Plug on the end.
The tool is run with the jets open at all times and therefore is generally short tripped. A Bilco Tough Boy™ Flow Check Sub should be run immediately below to optimize its effectiveness. When combined with the Bilco Tough Boy™ Multi-Use Waste Retriever below it, on a designated wear bushing retrieval run, the wellhead profile is hydro blasted and dislodged solids are captured, preventing them from falling into the wellbore.
Tough Boy™ Flow Check Sub
The Bilco Tough Boy™ flow check sub is an internal ball valve sub used to direct fluid flow to tools located above the check while allowing the tubing below to fill from annulus and bit. The flow check sub is generally used in a short trip application along with the Bilco Tough Boy™ Wellhead Jetting Tool, Bilco Tough Boy™ Magnet Jet Tool for BOPs, and Bilco Tough Boy™ Filter Tool.
This tool is primarily used below the Tough Boy™ Riser/Wellhead Jetting tool to direct all flow through the jet nozzles during a designated surface jetting run. By directing the flow through the jet nozzles exact exit velocities and flow rates can be established.
Tough Boy™ Circulating Tool
The Bilco Tough Boy™ Circulating Rool is used to boost flow rates at liner tops, which is essential for proper well bore cleaning. This tool enables an efficient exchange of well bore fluids or spotting of chemical pills. The Bilco Tough Boy™ Circulating Tool is always run in the hole with the ports closed and is opened through contact with the liner top.
The Bilco Tough Boy™ Circulating Tool is dressed for each job with regards to liner size and PBR ID. A landing nut below the shifting sleeve contacts the liner top or PBR. Tool activation is achieved by using string weight, only approximately 3000 pounds of down weight is needed to accomplish activation. As described above, once activated the tool operates in one of two possible modes. All circulation should be halted while activating or shifting this tool, to prevent seal damage.
The tool can use up to six shear pins to confirm landing on liner top. The shear pins can be adjusted from 10,000 to 50,000 by the amount of shear pins used.
Tough Boy™ Special Purpose Tools
Tough Boy™ Swivel Tool
The Bilco Tough Boy™ Swivel Tool is used to isolate the skinny portion of a tapered work string from potentially damaging torque. It is generally run above the Tough Boy™ Circulating Tool on small liner applications. Anticipated drilling below this tool must be carefully assessed prior to placing it in the work string since string rotation cannot be transmitted through this tool.
This tool is placed in the work string when torsional concerns exist. The Bilco Tough Boy™ Swivel Tool has a 150-ton load rating, which is sufficient for most tapered string application. It is recommended that PBTD be achieved and there is no anticipated drilling required below this tool. The work string above it is fully rotational and damaging torque below is eliminated.
Bilco Tough Boy™ Negative Test Packer
Bilco's Tough Boy™ Negative Test Packer (NTP) is designed to be activated and packed off by set down weight after landing on the liner top.
- The NTP is designed to work in conjunction with Bilco well bore Tough Boy clean-up tool line.
- When used with wellbore clean up tools, circulation is initiated and the test string is manipulated while following the operating procedures for the clean-up tool(s) used.
- After casing clean-up operations work string is landed on landing nut or the landing shoe located on the wellbore clean-up tool below the packer.
- Set-down weight is applied to activate the packer.
- A minimum of 55,000-lb set down weight is applied to close the packer equalizing valve and set the packer sealing element.
The proper packer size is chosen with regard to the production casing size and weight. Packer activation is achieved by using approximately 20,000-lb set down weight. Once activated a total set down weight of 55,000-lb should fully pack off the specially designed sealing element on the packer. Since the packer contains no casing slips test pressures create an end area piston force equal to the post setting effective end area times the test pressure. This force must be offset with pressure in the annulus above the packer and/or additional set down weight.
The Bilco Tough Boy™ NTP series packer is designed to be run after the casing has been properly cleaned or can be run in conjunction with a separate wellbore cleanout tool such as the Bilco Blade/Brush Type Tough Boy™ Casing Scraper. When run with the appropriate Bilco wellbore cleanout tool it is recommended to lower the packer to depth and land on the liner top PBR. The drill string should then be manipulated while following the operating procedure for the specific cleanout tool used.
