Tool Description
The Weatherford SPITFire release tool reliably releases downhole tools if the toolstring becomes stuck in the wellbore. This avoids wire breaks and facilitates efficient and clean retrieval of the toolstring using a conventional fishing overshot.
Running wireline and perforating technologies in horizontal or highly deviated wells presents a greater risk for stuck toolstrings or wire breakage. The SPITFire release tool is a wireline ballistic release technology that provides a reliable option for detaching from the stuck toolstring on command.
Unlike other wireline release technologies—that are less reliable due to weaker, pressure activated release mechanisms that routinely result in unintended releases—the SPITFire tool incorporates a high-strength frangible joint that requires booster detonation and will not release on loss of pressure containment of the toolstring.
The high tensile strength of the SPITFire release tool makes it suitable for use in high-impact perforating environments and allows it to be placed anywhere in the toolstring, even below perforating guns and in conjunction with jars.
The SPITFire release tool ensures the cable is retrieved out of the hole each time, mitigating the risk of stuck tools and expensive fishing operations.
