Abstract
A method of entering a previously-installed tubular in a lateral borehole from a primary borehole connected to the lateral borehole includes passing a downhole tool from the primary borehole into the lateral borehole, actuating an orientation mule shoe coupled to the downhole tool to lift the nose portion of the downhole tool into alignment with the tubular in the lateral borehole, and inserting the nose portion of the downhole tool into the tubular.
