Abstract
No-blow tool for braking rapid upward movement of a pulling tool and the device being retrieved caused by sudden upward fluid flow. The no-blow tool is assembled as part of a wire line tool assembly below jars and above the pulling tool. The no-blow tool includes three telescoping members, the lowest of which is secured to the pulling tool. Rapid upward movement of the pulling tool and the lowest telescoping member relative to the intermediate telescoping member cams serated slips radially outwardly to grip a well conduit, thereby braking the upward movement. A shearable connection between the upper and intermediate telescoping members permits jarring forces to be transmitted downwardly through the tool, without interference from the slip system.
