Abstract
Methods and apparatus for retrieving a fish from a wellbore. A method includes introducing a specialized fishing tool into the wellbore. The specialized fishing tool includes a fishing subassembly comprising a nonreflective interior, a shroud coupled to the fishing subassembly, and a camera disposed at least partially within the shroud and configured to view the interior of the fishing subassembly. The specialized fishing tool is conveyed downhole in the wellbore to a location of the fish. The fish is visualized with the camera. The fish is coupled to the fishing subassembly, and the fish is retrieved from the wellbore.
