Abstract
Methods and apparatus for installing a deflector in a primary wellbore and confirming lateral wellbore access. The hydraulic retrieving tool is coupled to the interior of the deflector and introduced into the primary wellbore. The hydraulic retrieving tool comprises a bullnose, a plurality of retractable deflective pads, and a retractable dog. The deflector comprises a deflection surface. The hydraulic retrieving tool is decoupled from the interior of the deflector at a depth in the primary wellbore by retracting the dog and the plurality of deflective pads. The hydraulic retrieving tool is removed from the interior of the deflector. The dog and the plurality of deflective pads on the hydraulic retrieving tool are expanded when the hydraulic retrieving tool is removed from the interior of the deflector. The hydraulic retrieving tool drifts at least a portion of the deflection surface to determine if there is lateral wellbore access.
