Abstract
A well fishing method and system is described. In at least one example of the invention, a method of retrieval of material (e.g., a tubing string) having broken control or monitoring lines from a cased well is provided. The method comprises: isolating, from the well casing, broken lines above the material to be retrieved, thereby creating a substantially axial work passage; grasping the material to be removed through the substantially axial work passage; and pulling the material to be retrieved and the restrained lines from the well. Example shrouds, probes and other members are also described.
