WELLBORE CLEANOUT TOOLS

The Ball Catcher Sub is run below a ball-activated tool and retains used metal balls of a specific diameter after they are released downhole from the ball-activated tools. Smaller diameter balls will pass through the Ball Catcher Sub and travel further down the string, enabling multiple ball-activated tools to be run in a single tool string and allowing for wireline to pass through.

The Ball Catcher Sub can be run with a modified ball retaining clip, ensuring balls cannot exit the sub, which can be necessary in a highly deviated well or when reverse circulating.

The Casing Brush is run as part of the drill string and cleans the inside of the wellbore casing as the string is run in the hole. The tool consists of a one-piece body, stabilizer sleeves and a non-rotating brushing bristle lantern. The body rotates through the lantern to avoid bristle wear during rotation, and the flexible lantern provides the force to contact and clean 360 degrees of the pipe.

The Casing Brush is available in a heavy-duty version with upper and lower mill rings to help break down large pieces of debris. The Casing Brush can be run as a stand-alone device or in conjunction with circulating tools, clean-up tools and cleaning agents.

The Vacuum Debris Removal Tool is a modular tool that works at relatively low pump rates and in light fluid with a low carrying capacity to perform effective clean-up operations. The modular design includes a single nozzle engine, a debris screening module and one or more debris chambers.

The engine module generates a localized high velocity reverse circulation at the end of the workstring to capture and recover heavier debris, such as perforation fragments or milling debris. A screening module prevents flow of larger particles through the tool and the debris chamber is designed with lifting caps to ensure all debris and fluid is 100% contained.  

The Casing Scraper is run as part of the drill string and cleans the inside of the wellbore casing as the string is run in the hole. The tool consists of a one-piece body, stabilizer sleeves and a non-rotating scraping bladed lantern. The stabilizer sleeves are casing friendly, and the bladed lantern-style scraper provides the flexibility and force to contact and clean 360 degrees of the pipe.

The Casing Scraper is available in a heavy-duty version with upper and lower mill rings to help break down large pieces of debris. The Casing Scraper can be run as a stand-alone device or in conjunction with circulating tools, clean-up tools and cleaning agents.

The Flat Bottom Magnet picks up large ferrous debris in the bottom of the wellbore that cannot be circulated into the annular path of a conventional drill string. The magnet can be deployed on the end of the workstring for fishing or for wellbore preparation activities such as displacement or dedicated cleanout.

The Flat Bottom Magnet includes a three-piece design with modular sleeves, forward facing circulation ports and draining ports. As the tool is lowered, a fluid circulation ring in the modular sleeve helps disturb non-ferrous debris so that the tool can locate directly on top of ferrous debris. Captured debris is not disturbed by fluid draining from ports on the modular sleeve.

The design of the In-Line Magnet allows the tool to pick up large volumes of ferrous debris while retaining the maximum amount of fluid bypass. The strong magnets are encased in steel for prolonged life and are fixed into precisely engineered ribs which greatly increase the magnet’s surface area and the volume of debris, which can be picked up and taken out of the hole.

The In-Line Magnet is available in a heavy-duty version with stabilizer mill sleeves to break down large pieces of debris that might exist in the wellbore. The stabilizer features tungsten carbide inserts which are casing friendly and give low torque and drag friction factors.

The Weight Set Circulating Tool is designed to allow increased annular velocity at a Liner Top to enable solids to be displaced out of the wellbore, as well as spotting of chemical pills and change-out of wellbore fluids. The tool is particularly suited to wells with small liner diameters in which well clean-up operations are performed prior to running completions or test strings.

The Weight Set Circulating Tool is functioned by slacking-off or picking-up the string, removing the need for darts or operating balls, and can be functioned as many times as required. Due to the Weight Set Circulating Tool’s clutch mechanism, only the drill string above the tool is rotated when the tool is in the open position, protecting the lower string from potentially damaging torque. When the tool is closed, the clutch is engaged allowing the whole string to be rotated with circulation being directed through the bit.

The Insert Junk Mill’s integral design and cutting structure provides improved strength and durability for milling away objects downhole that cannot be recovered through conventional fishing methods.

The addition of inserts increases the Insert Junk Mill’s longevity and rate of penetration. The mill meets NS-2 and DS-1 fishing standards and can be used in open and cased hole operations for milling general junk, fixed obstructions, production equipment and cemented tubulars.

The String Mill is run above a bottomhole milling tool, ensuring a smooth and obstruction-free wellbore. The clusterite and carbide mills are capable of withstanding the harshest conditions, and ensure the milled section maintains full gauge. The String Mill can be run in open and cased hole operations, and is ideal for removing casing impairments, performing cement cleanouts and back reaming.

The Ball-Drop Bypass Sub is run in a clean-up string and can be opened when a flow path is required between the inside diameter (ID) of the drill pipe and the annulus. The sub provides an additional means of equalizing pressure and fluid flow around the sub should the string become full of debris.

The Ball-Drop Open/Close Bypass Sub is opened to increase the flow velocity above a liner or casing crossover when a Multi-Function Circulating Tool is being utilized. The Ball-Drop Open/Close Bypass Sub has one set of ports and two internal ball seats that are activated to open and close the ports. Where it is desirable to re-open ports after the initial cycle, two open/close subs can be run in tandem.

The Drift Sub checks and verifies the drift inside diameter (ID) of casing, while running drill pipe into the well. The machined outside diameter (OD) of the gauge sleeve matches the API or special drift size of the casing. The gauge sleeve freely rotates on the body and remains static when the drill pipe is rotated, preventing wear or damage to the ID of the casing.

The Drift Sub can also be supplied with a customer specified OD to verify that a packer or other large diameter tool can be run safely. If required, two or more subs can be run together to create a longer drift, simulating the running of a longer packer or other tool.

The Riser Cleaning Tool allows operators to clean debris from the riser. The tool ensures removal of debris-laden fluids from the riser wall and prevents the remaining fluid sheath from depositing solids on sensitive completion string components.

The Riser Cleaning Tool’s wipers and brushes expand to effectively clean the larger ID riser as the workstring is run-in through a restrictive wellhead or BOP and retrieved from the hole. Loosened debris is collected in the integral junk bucket.

The De-Burring Tool is equipped with spring loaded expandable mill ribs to make contact with the full inside diameter (ID) of the casing or liner, removing perforation burrs with right hand rotation. The right-hand face of each mill rib is dressed with a carbide compound.

The bottom of the De-Burring Tool includes a fixed mill sleeve, also dressed with a carbide compound, to remove any severe ID restrictions before the mill ribs make contact. The upper end of the tool has a fixed stabilizer sleeve to provide balanced support and centralization to the mill ribs.

The Riser Junk Basket is a deepwater magnet that captures and retrieves metal debris dislodged during riser cleaning operations, especially when annular velocity in the riser may not be sufficient to carry large pieces of ferrous or nonferrous debris to the surface. The basket can be run above the Riser Validation Tool or another cleaning tool.

The Riser Junk Basket has several magnetic blades that are secured onto the outside diameter (OD) of the junk basket and attract metallic debris that falls from the riser. When a drop in annular velocity occurs above the tool, larger pieces of nonferrous debris fall out of the fluid flow into the junk basket.

The Riser Validation Tool cleans the riser’s inner walls and filters the entire fluid column

in the riser to ensure that all debris is captured within its filter. All fluid is filtered through the tool’s built-in validation screen, which is supported and protected by a perforated shroud around the outside of the screen and enables confirmation that the riser is free of debris.

The Jetting Sub assists in the cleaning of risers, BOPs, wellheads and casing/tubing hanger areas. The sub is built on a one-piece body and includes several replaceable jet nozzles that ensure maximum effective coverage of the area to be jetted.

The Jetting Sub is suited for operations on fixed platforms and land locations, as well as jackups and floating rigs. 

The Ball-Drop Circulating Tool is placed above bottomhole assemblies such as MWD and LWD tools, core barrels, and mud motors to provide an alternate circulation path for performing critical functions like placing loss circulation material in troublesome zones, avoiding plugging the bottomhole assemblies or damaging the LWD/MWD tools.

The Ball-Drop Circulating Tool is opened and closed using single-sized balls. A second ball size can be used to isolate the flow of fluid through the tool, if required. Once the tool is open, the majority of the flow will exit through the ports and a small amount of flow will go through the tool to cool down the BHA unless a shut-off ball is dropped.

The Liner Top Test Tool allows an inflow test (or negative test) to be conducted on a liner overlap and the liner shoe track on the same trip as the wellbore clean-up. The tool eliminates the need for either a controlled displacement of the whole well to a lower density fluid through the choke with the BOPs closed or a dedicated run of a retrievable packer to perform the test.

The Liner Top Test Tool is equipped with a packer element, an integral scraping lantern and an integral liner top dress mill. The tool also incorporates a closeable bypass under the packer element, which allows high circulation rates by increasing flow area past the restrictive outside diameter (OD) of the packer element.

The Ball-Drop Isolation Tool is designed so that high circulation rates can be used to displace the upper part of the well without any pressure being applied to the lower part of the well. The isolation tool is particularly suitable where there is a pressure sensitive tool or open hole below.

The Ball-Drop Isolation Tool includes two internal ball seats which are activated to open and close the tool. After the first ball is dropped and the isolation tool is closed, all flow through the string is directed out through the tool to the upper annulus. The Ball-Drop Isolation Tool also features a stabilizer and stabilizer mill profile to ensure there are no restrictions in the casing and to protect the diverter cup from any possible damage.
