  • Patent number: 9598922
    Abstract: A tool retrieves material from a well. The tool has a cylindrical tool body, malleable members, and a cylindrical jacket. The tool body defines a chamber adapted to receive material for retrieval. The malleable members are on the lower end of the tool body and preferably are made of a relatively hard, tough malleable material such as steel. They are bendable from an open position allowing material to enter the chamber to a closed position capturing the material. The jacket is mounted on the exterior of the tool body and has a mill surface which is adapted to bend the malleable members from the open position to the closed position. Relative axial movement of the jacket and the tool body causes the malleable members to bear on the mill surface and bend to the closed position.

  • Patent number: 8839864
    Abstract: Tools and methods for cutting multiple, co-extending casings in oil and gas wells. The tools comprise a cylindrical body and first and second sets of cutting blades. Each set of cutting blades is mounted to the body for actuation from a retracted, run-in position to an extended, cutting position. The cylindrical body is rotated and the first set of cutting blades is actuated to cut the co-extending casings within a first sweep diameter. The second set of cutting blades then is actuated to cut the co-extending casings beyond the first sweep diameter and within a second sweep diameter.
