Abstract

A combination tool for attaching to a stuck wireline tool, then cutting the wireline just above the stuck tool with a hydraulically driven cutter, allowing the wireline to be pulled out of the hole before fishing out the stuck tool. A side door can be provided on the work string, to allow rerouting of the wireline outside the work string, after which the stuck tool can be unstuck and repositioned within the well bore for completion of the downhole operation of the tool, prior to cutting the wireline free from the downhole tool.
