Zusammenfassung: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.
