ABSTRACT:
A packer having an orienting device is lowered in a well bore to a desired location and turned, if necessary, to point the orienting device in a selected direction, after which the packer is anchored against movement in the well bore. A whipstock, anchor and orienting mandrel are secured together in such manner that an orienting device on the mandrel, companion to the packer orienting device, is aligned with the whipstock. The whipstock, anchor and mandrel combination is then lowered in the well bore, the mandrel orienting device engaging the packer orienting device, effecting turning of the combination to point the whipstock in the same final direction as the packer orienting device, whereupon the anchor is secured to the packer to prevent movement of the whipstock from its final oriented position, which is the direction that a suitable cutting tool is to be deflected by the whipstock to cut a window in a well casing in the well bore, to sidetrack the well bore, or to perform both of these operations.
