Abstract: A method of cutting a control line mounted on an outer surface of a downhole tubular that includes providing a cutting tool having a main body, and a cutting head on a lower end of the body that rotates with respect to the body. A cutting blade is on a lower end of the cutting head, which is rotatable by a motor, where the blade is selectively pivoted radially outward from an axis of the cutting head. As the cutting head rotates, the cutting blade orbits within the tubular axially offset from the axis. When the tool is inserted into the tubular, the radial offset of the blade is controlled so it pivots radially outward into contact with the tubular when the blade approaches an azimuthal area proximate the control line. The cutting blade is retracted when its orbit moves it past the azimuthal area proximate the control line.

Abstract: A double-acting pipe cutting band saw apparatus and method for using the same are capable of cutting a relatively large workpiece with a relatively small size band saw, furthermore, it improves the cutting efficiency and life of the band saw. Since the pipe to be cut is put on a rotary table which is mounted a slide table, it can be continuously rotated and moved with respect to the band saw assembly during the cutting operation. Hence, the pipe to be cut can be completely cut by a band saw whose operable cutting length of the band saw does not have to be larger than the diameter of the pipe, which reduces cutting time while improving cutting efficiency. On top of that, the service life of the band saw is extended since the cutting operation is not just performed by the rotation of the band saw.
