Abstract: A tubular cleaning tool can be delivered through tubing and then hydraulically or mechanically actuated to rotate blades about respective pivot location into approximately a 45 degree orientation for commencement of tool rotation and cleaning a larger tubular that is below. Each of the blades has a cantilevered distal end that further features at least one articulated link. The outer periphery of the articulated distal segment has hard facing to enhance the cleaning effect and to reduce blade wear. The remainder of the blade outer surface can also have hard facing for similar reasons. The distal segment can be biased toward the surrounding tubular when the blades extend to put the segment in the needed orientation for cleaning.

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.
