Abstract
A wellbore intervention tool for use in penetrating an obstruction in a wellbore includes a cutting tool having at least one rotating cutter member for penetrating the obstruction. A displacement mechanism coupled to the cutting tool sets and adjusts a cutting position of the cutting tool relative to a tool axis. A sweeper coupled to the displacement mechanism deflects the displacement mechanism about the tool axis, and the cutting tool is deflected with the displacement mechanism.

A wellbore intervention tool for use in penetrating an obstruction in a wellbore, comprising:
- a cutting tool having at least one rotating cutter member for penetrating the obstruction;
- a displacement mechanism coupled to the cutting tool and operable to set and adjust a cutting position of the cutting tool relative to a tool axis;
- a sweeper coupled to the displacement mechanism and operable to deflect the displacement mechanism about the tool axis, wherein the cutting tool is deflected with the displacement mechanism;
- and
- wherein the rotating cutter member has a rotation axis at all times substantially perpendicular to the tool axis.
A method of penetrating an obstruction in a wellbore, comprising:
- lowering a wellbore intervention tool into a wellbore, the wellbore intervention tool comprising a cutting tool having at least one rotating cutter member, a displacement mechanism coupled to the cutting tool, and a sweeper coupled to the displacement mechanism;
- positioning the least one rotating cutter member against the obstruction;
- rotating the at least one rotating cutter member while the at least one rotating cutter member is positioned against the obstruction wherein the rotating cutter member has a rotation axis at all times substantially perpendicular to a tool axis;
- and
- operating the sweeper to deflect the displacement mechanism about the tool axis during at least a portion of the rotating the at least one rotating cutter member.
