Tool String
A Wireline Tool String is made up of set Tools (Work String) to do specific Wireline operations down-hole. The Tools are attached to the Wire by means of a Rope Socket.
Below the Rope Socket a Swivel Joint is placed to avoid “torsion” or twisting of the Wire.
In order to overcome the friction of the Stuffing Box packing and well pressures, Stem is used as weight to lower the tool string down hole. The weight of the stem is also used to generate impact force when performing jarring action. The Jars enable the impact of the tool string in either direction, up or down, against any encountered obstruction down hole.
To intensify an impact force to the tool string, an Accelerator can be used. Finally, to obtain the flexibility to the tool string, a Knuckle Joint is placed above the selected tool to do a specific function as needed.
The following links list a selection of Tools which are used in a Typical Tool String; chosen by the Operator to suit the work to be performed.
Rebco can supply Tool Strings from 3/8” to 2 1/2” diameters, with Threaded Connections as well as QLS (Quick Lock System), Rebco Type ‘RQLS’ and/or Rebco Type ‘RQLD’ Connections.

Type 'RC' Rope Socket Assembly
Rebco Type 'RC' Rope Socket is designed to connect a Capsulated Line to the Tool String. The wear bushing and swivel design, prevent damage to the wire. The Capsulated Line is inserted through the wear bushing, and the Body. The clamp is tightened to the line and pulled into the Rope Socket. A connector sub is slipped over the bottom sub, a retainer is screwed and secured by a set screw. The bottom sub and the connector sub are made up to the Body.
Type 'CGO' Rope Socket Assembly & Additional Types of Rope Sockets
Rebco Type 'CGO' Rope Sockets are designed for use with small stranded lines, up to 1/4" diameter. Similar in design as Rebco Type 'CO' Rope Sockets, the Tool has an additional swivel bottom.
Type 'HO' Heavy Duty Rope Socket Assembly - Threaded Connection
Rebco Type 'HO' Heavy Duty Rope Socket is designed for Heavy Duty Wireline Work. The wire should be passed through the body and the clamp Sub-Assembly. The unique design will trap the wire; held in place by socket screws.
Type 'HD' Heavy Duty Rope Socket Assembly - 'QLS' Connection
Rebco Type 'HD' Heavy Duty Rope Socket is designed for Heavy Duty Wireline Work. Type 'HD' Rope Socket is made up of Type 'HO' Rope Socket Assembly with an 'RQLD' Bottom Sub-Assembly. The wire should be passed through the body and the clamp Sub-Assembly. The unique design will trap the wire; held in place by socket screws.
Type 'HO' Swivel Joint Assembly
Rebco Type 'HO' Swivel Joint was designed to minimize the twisting of the Wireline when running the Tools down hole. Type 'HO' Swivel Joint is with Threaded Connection.
Type 'HD' Swivel Joint Assembly
Rebco Type 'HD' Swivel Joint was designed to minimize the twisting of the Wireline when running the Tools down hole. Type 'HD' Swivel Joint is with 'QLS' - 'RQLD' Connection.

Type 'AO', 'AD' and 'AS' Link Jar Assembly
Link Jars consist of two interlocking steel links with a Fishing Neck and Pin-Box connection. The interlocking steel links can be extended or collapsed by manipulating the Wireline at the surface to produce upward or downward jarring. The intensity of jarring impact depends on the weight of the Wireline Stem (PRODUCT CODE 101) installed above the Jar, and the stroke of the Jar as well as the wellbore conditions.
Type 'BO' and 'BD' Hydraulic Jar Assembly
Rebco Hydraulic Jar is used to apply high impact force. The closed hydraulic system within the jar makes it possible for the jarring impact to be controlled. The intensity of the impact is proportionate to the full force on the Wireline and to the weight of Stem.
Type 'CO' and 'CD' Knuckle Jar Assembly
Rebco Knuckle Jar is similar in design to the Knuckle Joint (Product Code 103), the difference being is that the Knuckle Jar in addition to its flexibility is used as a Tubular Jar (Product Code 102). Typically, Knuckle Jar is used with BHP work and light duty Wireline applications.
Type 'DO' and 'DD' Tubular Jar Assembly
Rebco Tubular Jar consists of a perforated tube for fluid by-pass, and a mandrel connected to the fishing neck. A telescoping mandrel is extended or collapsed within the tube by manipulating the Wireline at the surface, thus jarring action is produced. As in Type 'AO' Link Jars, the intensity of jarring impact depends on the weight of Stem and wellbore conditions.
Type 'SO' and 'SD' Spring Jar Assembly
Rebco Spring Jar is a telescoping up-stroke Jar installed below the Stem. The impact force can be predetermined at surface by the Operator with the Calibration Unit shown below. Rebco offers Spring Jars with Threaded or QLS Connections.
Type 'EO' and 'ED' Accelerator Assembly
Rebco Accelerator is designed to be used with various Jars. The Accelerator assists in maintaining a constant pull as the Jars open, and upon release, the impact is intensified.
Rebco offers Accelerator with Threaded and QLS Connections.
