An indicator device has been invented for indicating correct orientation of an orienting receptacle and an associated wellbore tool secured to the orienting receptacle with respect to an anchor fixed in an interior of a longitudinal channel, the anchor having a top end, the indicator device having a rod having a top end and a bottom end and movably disposed in and extending through a tool central channel of the wellbore tool and with a bottom portion extending into the orienting receptacle; the bottom end of the rod disposed for contact by the top end of the anchor and the rod movable upwardly in the tool central channel by the top end of the anchor as the orienting receptacle moves down on the anchor to correctly orient the wellbore tool. A wellbore tool system has been invented for disposition in a longitudinal bore channel above and with respect to an anchor secured in the longitudinal bore channel, the anchor having a top end, the system having a wellbore tool having a top end, a bottom end, and a longitudinal tool channel therein; an orientation receptacle for receiving and contacting the top end of the anchor for orientation with respect thereto; and a movable rod with a top portion movably disposed in the longitudinal tool channel in the wellbore tool, and with a bottom portion with a bottom end projecting into the longitudinal orienting channel of the orientation receptacle for contact of the bottom end of the rod by the top end of the anchor for upward movement of the rod indicating that the orientation receptacle and its associated wellbore tool are correctly oriented with respect to the anchor and the longitudinal bore channel. A whipstock system has been invented which has such a wellbore tool system. |
