  • Whipstock and deflector assembly for multilateral wellbores
    Patent number: 9951573
    Abstract: A method includes conveying a whipstock and a latch anchor into a parent wellbore, the latch anchor being attached to the whipstock at a releasable connection and the parent wellbore being lined with casing that includes a latch coupling. The latch anchor is secured to the latch coupling and the whipstock is then separated from the latch anchor at the releasable connection and thereby exposing a portion of the releasable connection. The whipstock is then removed from the parent wellbore and a completion deflector is subsequently conveyed into the parent wellbore in combination with lateral tubing (with or without a multilateral junction positioned thereabove), and the completion deflector is attached to the latch coupling at the releasable connection. The lateral tubing (with or without multilateral junction positioned thereabove) is then installed to correct depth.
