Abstract
Apparatus and methods to perform operations in a wellbore using downhole tools having movable sections are described. In one described example, a downhole tool for use in a wellbore includes a first extendable anchor to contact a wall of the wellbore to fix the tool at a location in the wellbore. The downhole tool also includes a first tool of the downhole tool to perform a first operation at the location in the wellbore, and a second tool of the downhole tool spaced from the first tool and to perform a second operation. Additionally, the downhole tool includes an extendable member to move the second tool to the location while the anchor is in contact with the wall of the wellbore to perform the second operation after the first operation.
