Abstract: A method of positioning a bottom hole assembly in a wellbore includes lowering the bottom hole assembly into the wellbore. The bottom hole assembly has a whipstock, a downhole tool, and a cleaning tool having a cleaning element. The method also includes cleaning at least a portion of a wall of the wellbore using the cleaning tool, and activating the downhole tool to engage the cleaned portion of the wall.

Abstract: A bottom hole assembly for use in a wellbore includes a whipstock; a downhole tool coupled to the whipstock; and a cleaning tool coupled to the downhole tool for cleaning a portion of a wall of the wellbore, wherein the downhole tool is configured to engage the cleaned portion of the wall. In one example, the cleaning tool includes a body and a plurality of cleaning elements for cleaning the portion of the wall.

Abstract: An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.
