Tool Description
The Weatherford Blockbuster jar is designed to compensate for the limited amount of overpull available to free stuck tools. The advanced technology of this tool protects against time consuming and expensive stuck tool strings and fishing jobs.
Using energy stored in compressed springs and the slickline itself, the Blockbuster jar creates a powerful upward impulse to increase the force available to free stuck tools. The jar activation force can be easily adjusted at the surface while in the string to account for different operations.
The Blockbuster jar is designed to provide extra-high impact for ultra-demanding slickline operations, including heavy duty fishing, with solid or braided wirelines, delivering over 25,000 lb (11,339 kg) of impact force.
