Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating in a wellbore having a tubular comprising: providing a cutting tool having a cutting blade; deploying the cutting tool to a designated location in the tubular; rotating the cutting blade; forming a slot through an azimuthal portion of the tubular by orbiting the cutting blade about an axis of the cutting tool and along a path that is farther away from an axis of the cutting tool when along an azimuthal portion adjacent the slot, t…
