Coil tubing fishing operations utilize a first time technique to strip voer and recover 9500 feet of stuck slickline wire

摘要

Coil tubing was utilized to perform a modified strip over operaton and recover 9500 ft. of stuck slickline (0.108 in.) wire. The technique, through to be an industry first, eliminated the risky option of recovering the wire piecemeal via conventional wireline fishing operations. This paper documents the background that lead to the development of the technique. An operational summary details its implementation and illustrations are included of the special tools and techniques employed.
