Abstract

A method includes conveying a washover whipstock coupled to an orienting latch anchor into a parent wellbore lined with casing and securing the orienting latch anchor to the casing. A washover tool couples to and removes the washover whipstock from the parent wellbore, and thereby exposes a releasable orienting coupling of the orienting latch anchor. A workover whipstock coupled to a junction isolation tool is then conveyed into the parent wellbore and the workover whipstock is coupled to the orienting latch anchor at the releasable orienting coupling. The junction isolation tool is separated from the workover whipstock and advanced into the lateral wellbore, following which the junction isolation tool is retracted back into the parent wellbore to be re-attached to the workover whipstock to remove the workover whipstock from the parent wellbore.
