Glossary OTHER TYPES OF PLUG CHOKES OTHER TYPES OF PLUG CHOKES D. Circulating Type Chokes for Nipples (Product Code 20) Circulating Chokes restrict fluid flow in the tubing string and permit circulation from above, making them the tool of choice for flow measurement and production rate management. The restriction is created by a Bean (designated by a 64ths-of-an-inch orifice) seated in the choke body; a wide range of orifice sizes is available, allowing the operator to calibrate the flow rate to the well's specific requirements. Circulating Chokes are also commonly used to reduce production intentionally when full-rate flow is not desirable. Types available include ROTAX , ROTAR , ROTFWT , and ROTRZT . How to Order: Product Code 20. Specify nipple profile type, seal bore size, material, and Bean orifice size in 64ths of an inch. E. Circulating Blanking Plugs for Nipples (Product Code 20) Circulating Blanking Plugs hold pressure from below while allowing circulation from above, and can be held open to bypass fluid freely while running or pulling the plug. An internal valve is depressed during run-in and pull-out to allow fluid bypass, reducing hydraulic drag on the tool string. Types available include ROTCX , ROTCR , ROTFSB , ROTFWB , ROTRZB , ROTFGB , ROTFMB , and ROTRKB , covering the full range of BF , BR , and related nipple profiles in the Rebco completion system. How to Order: Product Code 20. Specify the nipple profile type, seal bore size, and required material. F. Pump-Through Plugs (Product Code 21) Pump-Through Plugs hold pressure from below while allowing fluid to be pumped downward through the plug assembly from above, without requiring the plug to be pulled. This allows the operator to displace fluids below the plug, stimulate a zone, or perform injection operations without first removing the plug with a wireline trip. Types available include RXO , RXN , XRO , and XRN , selected based on the nipple profile and seal bore size. How to Order: Product Code 21. Specify the nipple profile, seal bore size, and required material. G. Plug Chokes for Tubing (Product Code 20) Plug Chokes for Tubing are designed to withstand limited pressure differentials while allowing circulation from above in wells where no Landing Nipples are present, and set directly in the tubing bore. They are the tubing-set equivalent of the nipple-set circulating choke family, and the types available include ROTCW , ROTDW , ROTDD , and ROTCD , each suited to specific tubing sizes and pressure-holding requirements. How to Order: Product Code 20. Specify tubing size, type ( ROTCW , ROTDW , ROTDD , or ROTCD ), seal bore size, and material required.

Glossary JDC Pulling Tool (Short Reach) Assembly JDC Pulling Tool (Short Reach) Assembly The Rebco JDC is a shear-down, short-reach pulling tool designed to retrieve sub-surface devices with external fishing necks in applications where the fishing neck is positioned close to the top of the device, meaning a shorter reach is both sufficient and preferred. The JDC engages the external fishing neck by allowing its dogs to snap over and behind the fishing neck shoulder as the tool is lowered over the device. Once latched, upward tension on the wireline lifts the device from its set position. If the device is stuck and cannot be freed, a firm downward jar stroke shears the internal shear pin, collapsing the dogs inward and releasing the JDC from the fishing neck, allowing the tool string to be retrieved without the device. The short-reach configuration of the JDC means the distance between the bottom of the core and the dog-engaging surface is intentionally minimized, making the JDC the correct choice when the gap between the top of the landing nipple and the fishing neck is small, or when working in completions with closely spaced nipples where a long-reach tool risks engaging the wrong fishing neck. Changing the core is all that is required to obtain a different reach within the same nominal size; no full tool replacement is necessary. Available in nominal sizes 1¼" through 4", engaging fishing neck ODs from 0.875" to 3.125". Alloy construction throughout. How to Order: Available in assembly numbers from 400703021250 (1¼") to 400703024000 (4"). Specify the nominal size and confirm the reach against the device's fishing neck dimensions for the retrieved device.

Glossary ROTJ Running Tool Assembly ROTJ Running Tool Assembly The Rebco ROTJ Running Tool is a direct-shear-pin engagement running tool designed specifically for setting sub-surface devices with external fishing necks. The ROTJ connects to the device by threading a shear pin through the running tool body and into the fishing neck of the sub-surface device, holding the two together as a single unit during the trip downhole. Once the device reaches its target depth and is properly seated within the landing nipple, an upward jar stroke shears the retaining pin, freeing the running tool from the device and allowing the tool string to be retrieved to the surface. The ROTJ is a straightforward, reliable tool valued for its simplicity. There are no collet fingers, no latching dogs, and no hydraulic components to service. The running neck ID, which determines the size of the fishing neck the ROTJ will engage, varies by the type of sub-surface tool being installed. Operators should specify the fishing neck size or tool type when ordering to ensure proper fit. Available in nominal sizes ¾" through 4", with lengths ranging from 2.44" to 5.62". All sizes feature alloy construction with matched-pitch pin threads and fishing-neck connections. How to Order: Specify the nominal size and fishing neck size, or the tool type, when ordering, as the running neck ID varies by sub-surface device. Assembly numbers range from 410736 (¾") to 410725 (4"). Contact Rebco if the standard ROTJ is not suitable for the specific fishing neck configuration.

Glossary ROTFB-2 Equalizing Check Valve Assembly ROTFB-2 Equalizing Check Valve Assembly The Rebco ROTFB-2 is an Equalizing Check Valve (Standing Valve) designed to be set into ROTF Landing Nipple profiles. Its fundamental function is one-way flow control: it prevents downward fluid flow through the nipple while allowing full, unrestricted upward flow, the defining behaviour of a standing valve used in tubing testing and fluid control applications. The ROTFB-2 is not mechanically locked into the nipple profile. Instead, the No-Go shoulder built into the Packing Mandrel seats against the bottom of the ROTF nipple bore, and the nipple's No-Go shoulder prevents any downward movement of the assembly. This means the tool rests and seals on its No-Go, which cannot be pushed through, but it is not latched or locked in place by keys or slips. To protect the packer elements and ensure a safe retrieval, the ROTFB-2 incorporates a built-in equalizing feature that equalizes wellbore pressure across the check valve before the pulling tool breaks the packing seal and the assembly is retrieved to surface. Attempting to pull the ROTFB-2 without equalizing first would subject the pulling tool and wireline to the full differential pressure across the valve, potentially causing a dangerous condition. Available in nominal sizes 2⅜" through 4½", covering seal bore sizes from 1.781" to 3.813". Run using the ROTC-1 Running Tool; retrieved using the SB Pulling Tool or JDC Pulling Tool, both selected by nominal size. Available in a variety of materials to suit downhole conditions. How to Order: Product Code 12. Specify nominal size, seal bore size, and material. Specify ROTF nipple profile compatibility when ordering.
