Abstract
A mandrel that includes a keyed outer diameter, wherein the keyed outer diameter are configured to interface with indicators on an inner diameter of housing when rotated in a first direction and freely slide over the indicators when rotated in a second direction.
Claims12
A downhole tool comprising:
- a housing;
- a mandrel configured to rotate in a first direction and a second direction, the mandrel being radially aligned with the housing, wherein the mandrel is configured to rotate in the first direction without rotating the housing, and the mandrel and the housing are configured to simultaneously rotate in the second direction;
- a clutch positioned radially between the mandrel and the housing, the housing including keys, wherein an outer diameter associated with the keys is configured to dynamically change, an inner surface of the keys including cutouts that decrease a radial thickness of the keys;
- radially expandable elements configured to elongate and compress based on the positioning of the keys, wherein the radially expandable elements elongate when aligned with indicators, an outer surface of the radially expandable elements being configured to be positioned within the cutouts;
- wherein a proximal end of the clutch includes a first lip that decreases the radial thickness of the clutch, and a distal end of the clutch includes a second lip that decreases the radial thickness of the clutch;
- an upper stabilizer positioned radially over an outer surface of the first lip;
- and
- a lower stabilizer positioned radially over an outer surface of the second lip, the upper stabilizer and the lower stabilizer being configured to limit the radial movement of the clutch.

A method for a downhole tool comprising:
- rotating a mandrel in a first direction while a housing remains rotationally fixed;
- rotating the mandrel and the housing simultaneously in a second direction, wherein the mandrel transfers torque to the housing to rotate the housing in the second direction, the mandrel being radially aligned with the housing, the housing including keys, wherein an inner surface of the keys includes a cutout that decreases a radial thickness of the keys;
- elongating and compressing radially expandable elements based on a positioning of the keys, wherein the radially expandable elements elongate when aligned with indicators, an outer surface of the radially expandable elements being configured to be positioned within the cutouts, wherein a proximal end of the clutch includes a first lip that decreases the radial thickness of the clutch, and a distal end of the clutch includes a second lip that decreases the radial thickness of the clutch;
- positioning an upper stabilizer radially over an outer surface of the first lip;
- positioning a lower stabilizer over the second lip;
- and
- limiting the radial movement of the clutch via the upper stabilizer and the lower stabilizer.
