A downhole workover tool includes an elongate, cylindrical body having opposing lower and upper ends and defining an interior sized to receive a selected portion of a wellbore tubular via the lower end, and a plurality of insert tools receivable within a corresponding plurality of insert chambers (cavities) provided about an outer circumference of the body. At least one of the plurality of insert tools provides slips operable to grippingly engage an outer circumference of the selected portion of the wellbore tubular and thereby prevent the upper portion of the wellbore tubular from reversing out of the interior once received therein. The tool is then operated to mechanically or chemically cut the selected portion of the wellbore tubular.

Systems and methods for downhole tubular cutting applications can include a cutting tool that with a cutting head, an anchor module, and a hydraulic module that actuates both. Arms of the anchor module open to an inner surface of a tube prior to blades of the cutting head opening to the inner surface. The blades can be operated by a piston. The piston can include a detent that travels across an actuation profile. This can allow a processor to track the cutting position. The processor can adjust the rotational speed of the blades based on feedback from the system.

A method for locating and retrieving a line, tube or conduit (line) disposed in a well includes moving an intervention tool into a part of the well wherein the line is accessible to the tool when the tool is conveyed into the well from within a first tubular string. A first gripper arm is rotated in a first direction around an inner circumference of the first tubular string by operating a first motor in the tool until the first gripper arm contacts the line. A second gripper arm is rotated in a second direction opposed to the first direction around the inner circumference until the second gripper arm contacts the line by operating the first motor in a same direction as for rotating the first gripper arm. The first gripper arm and the second gripped arm are retracted to move the line toward the intervention tool.
