Abstract: A self orienting liner hanger system including a bent sub, an indexing sub in operable communication with the bent sub, a hanger assembly in operable communication with the indexing sub, and a profile connected with the hanger assembly. Yet further disclosed herein is a method for constructing a junction between a primary borehole and a lateral borehole. The method includes installing a window sleeve at the junction, running a liner hanger into the sleeve, cycling an indexing sub of the hanger until a bent sub of the hanger exits the window, and running the hanger into engagement with the sleeve.

Abstract: A full bore selective location and orientation system includes a nipple installable in a tubular string and having internal location and orientation features of known configuration and a locating device runable within the tubular string and having location and orientation features engageable with said internal features of said nipple. A method of locating and orientating a downhole tool including installing a tubular nipple having a particular inside dimensions configuration in a tubular string running a locating device having a complementary outside dimensions configuration to engage with said inside dimensions configuration and rotating said locating device to a position where a biased member extends from said locating device into a recess in said tubular member.
