Glossary JO Unlatching Tool Assembly with J Head JO Unlatching Tool Assembly with J Head The Rebco JO Unlatching Tool with J Head is the instrument deployment system used to lower a recording instrument or Bomb Well assembly to depth and leave it on top of a pre-set depth stop, such as a Collar Stop, Slip Stop, or DO Collar Lock, without the need for any separate latching, setting, or jarring action at the instrument itself. The J Head is attached directly to the bottom of the instrument or Bomb Well. The JO Running Tool engages the J Head through a J-slot mechanism. As the assembly lands on the pre-set stop and the weight of the tool string acts downward, the J-slot geometry automatically unlatches the J Head, releasing the JO Running Tool and leaving the instrument assembly at depth while the wireline tool string is retrieved to the surface. When the survey is complete, and the instrument must be retrieved, the J Head's external fishing neck is engaged with the appropriate Pulling Tool (Section IV, Product Code 40), and the full instrument assembly is pulled back to the surface. The J Head is available with either a ¾"–16 Box Thread (Amerada) or 15/16"–10 Box Thread (Sucker Rod) lower connection to match the instrument thread, and J Heads with 15/16"–10 connections are available on request. The JO Running Tool is selected by nominal size (2" covers 2⅜" through 3½" tubing). See Section III, Page III-25 for running tool sizing. How to Order: Assembly number 4107202000 (¾"-16 Box Thread) or 4107202001 for 2⅜"-3½" tubing size. Specify box thread connection type. For J Heads ordered as part of the assembly, specify fishing neck size (1.187" or 1.375") and box thread required.

Glossary Equalizing Sub-Assemblies - Accessories Equalizing Sub-Assemblies - Accessories The accessories in Section XV are the individual components that combine with the equalizing and bottom sub-assemblies to complete each assembly configuration. The A Cage and B Cage are the outer housing components that contain the valve, bean, or ball and seat mechanism in each respective sub-assembly; the A Cage is used in circulating applications, and the B Cage is used in choke and bean applications. The API Cross Over Mandrel is the connecting component that adapts between the Lock Mandrel body thread and the Seal Unit, allowing different lock mandrel and nipple combinations to be used with the same circulating or choke bottom assemblies. The AO Bean and BT Bean are the calibrated flow restriction inserts used inside the A Cage and B Cage, respectively, and are available in 1/64" orifice increments, giving the operator precise control over flow restriction without replacing the entire subassembly. The K Equalizing Shear Plug is a safety device that incorporates a shear element, allowing the equalizing pathway to be opened by applying a specific overpull force on the wireline, providing a backup equalization method if the primary prong-actuated equalization fails or is not accessible. Product Code 21 applies to the A Cage, AO Bean, and standard accessories; Product Code 195 applies to the B Cage, API Cross Over Mandrel, K Equalizing Shear Plug, and BT Bean. How to Order: Product Code 21 ( A Cage, AO Bean), Product Code 195 ( B Cage, API Cross Over Mandrel, K Equalizing Shear Plug, BT Bean).

Glossary BG Running Tool BG Running Tool The Rebco BG Running Tool is a locating and running tool purpose-built for positioning sub-surface accessories equipped with ROTS-1 or ROTS-2 Lock Sub-Assemblies into their corresponding selective seal profiles within the wellbore. Its primary function is not to set the device by jarring, but to accurately locate a specific seal profile among several within a multi-nipple completion string, a critical distinction in selective completions, where the wrong profile must not be accidentally engaged. The BG operates by engaging the collet or locating feature of the Lock Sub-Assembly against the correct profile recess as the tool string is lowered. Once the proper profile is located and the accessory is seated, the running tool is released and retrieved, leaving the sub-surface device locked in place. This makes the BG an essential tool in gas lift, chemical injection, and other multi-zone selective applications where precise depth control and profile selectivity are paramount. How to Order: Available in assembly numbers 4101052370 (2⅜"), 4101052870 (2½"), 4101053500 (3½"), and 4101054500 (4½").

Glossary A Stem (Weight Bar) A Stem (Weight Bar) The Rebco A Solid Bar Stem is a solid alloy steel bar that serves as the primary weight source in the wireline tool string. Its mass overcomes three competing forces that prevent the tool string from entering the well: wellhead pressure acting on the wireline's cross-sectional area, stuffing box packing friction, and wellbore fluid drag. The same weight that drives the string downhole is also the source of impact energy when jarring; the greater the stem weight above the jars, the higher the jarring impact force delivered to the downhole tool. As a general rule of thumb, a minimum of 5 feet of 1½" OD stem (approximately 29.2 lbs) is used for well pressures up to 1,000 psi, with approximately 2 additional feet added for each subsequent 1,000 psi. Available in standard lengths of 2 ft, 3 ft, and 5 ft, in standard threaded sucker rod connections from ⅜" to 2½" OD. Smaller ⅜" and ½" OD versions are available for velocity string completions. All Rebco stems are manufactured with machined flats for safer wrenching; never grip the fishing neck.

Glossary CD Sampler (Drive Down) Bailer Assembly CD Sampler (Drive Down) Bailer Assembly The Rebco CD Sampler/Drive-Down Bailer is a dual-purpose tool engineered to take a physical debris sample from the obstruction site, or, in its longer drive-down configuration, to physically penetrate and capture a column of compacted debris for removal from the wellbore. The tool body consists of a top sub with a fishing neck, a primary collection tube, and an interchangeable bottom shoe valve. The angled mule shoe at the lower end helps guide the tool into debris and cuts a path of entry on the downstroke, while the ball or flapper valve at the base captures and retains the material on recovery. In the sampler configuration (2 ft tube length), the tool takes a representative grab sample of debris at the work site, allowing the operator to assess debris type, particle size, and composition at the surface before selecting the most appropriate full-scale bailing or remediation method. In the drive-down configuration (5 ft tube length), the tool is used to physically penetrate and extract a full column of compacted sand, scale, or granular debris that cannot be lifted by pump action alone. The angled mule shoe helps force entry into hard-packed material on the downstroke. Available with ball-type, flapper-type, or junk-catcher-type bottom shoe configurations, all of which are also available with optional mule shoe bottoms. Both 2 ft sample tube and 5 ft drive-down tube lengths are available as standard. Alternative tube lengths available on request. Available in 1½"–4" OD.
