Abstract

Coiled tubing spears for retrieving a section of cut coiled tubing comprises a mandrel having attachment members, e.g., spears, at upper and lower ends for facilitating connection of the upper end of the mandrel to a spooled section of coiled tubing and the lower end of the mandrel to a section of cut coiled tubing disposed in a wellbore. Coiled tubing spears comprise one or more centralizers that are releasably secured to the mandrel. The centralizer(s) facilitate lining up a lower attachment member, or spear, with the bore of the section of cut coiled tubing so that the mandrel can be secured to the cut coiled tubing for retrieval. During retrieval of the cut coiled tubing, the centralizer(s) are released from the mandrel so that the mandrel and attachment members can continue through an injector head.
