Abstract
A method of downhole operations with a wireline deployed tool that has become stuck downhole. The wireline is selectively detached from the stuck tool, and a tubular is attached to a coupling provided with the tool. The tool is unstuck by applying upward and downward forces to the tool with the tubular. The coupling further provides communication between a line in the tubular and the downhole tool, thereby providing communication between the tool and surface. Thus, after unsticking the tool, wellbore operations can continue with the tool attached onto the tubular.
