  • Fishing tool
    Patent number: 9027645
    Abstract: Fishing tools for retrieving objects, i.e., “fish,” lodged within a wellbore are disclosed. The fishing tool comprises a tubular member having a tubular member bore with at least one profiled surface or insert disposed within or along the inner wall surface of the tubular member bore. The profiled surface or insert provides a fishing profile shaped to allow a portion of the fish to move past the fishing profile so that the fishing profile is disposed below the portion of the fish. The tubular member can then be actuated, such as through rotation, to align the portion of the fish with a shoulder of the fishing profile. Upward movement of the tool engages the shoulder with the portion of the fish. Continued upward movement of the tool facilitates retrieval of the fish from the wellbore.
