Selectively actuatable expandable underreamer/stabilizer
First Claim
1. An expandable downhole tool for use within a wellbore, comprising:
- a tubular body having an axial flowbore extending therethrough;
at least one moveable arm; and
a selectively actuatable sleeve that prevents or allows the at least one moveable arm to translate between a collapsed position and an expanded position.

Abstract
An expandable downhole tool comprises a tubular body having an axial flowbore extending therethrough, at least one moveable arm, and a selectively actuatable sleeve that prevents or allows the at least one moveable arm to translate between a collapsed position and an expanded position. A method of expanding a downhole tool comprises disposing the downhole tool comprising at least one moveable arm within the wellbore, biasing the at least one moveable arm to a collapsed position corresponding to an initial diameter of the downhole tool, flowing a fluid through an axial flowbore extending through the downhole tool while preventing the fluid from communicating with a different flowpath of the downhole tool, allowing the fluid to communicate with the different flowpath by introducing an actuator into the wellbore, and causing the at least one moveable arm to translate to an expanded position corresponding to an expanded diameter of the downhole tool.

27. An expandable downhole tool for use within a wellbore, comprising:
-
a tubular body; and
at least one moveable arm;
wherein the expandable downhole tool is selectively actuatable to allow or prevent the at least one moveable arm to translate between a collapsed position and an expanded position in response to a fluid flowing through the tubular body.
