PRODUCT CODE 102: Tubular Jars -Type DO and DD Tubular Jars - Tool String
Rebco JARS are the main work Tools of a Wireline Tool String; it is through their proper manipulation that all wire line sub-surface operations are possible.
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.
1. Type 'DO' Tubular Jar - Threaded Connections.
2. Type 'DD' Tubular Jar - 'QLS' Connections.
