Title: MULTILATERAL ACCESS WITH REAL-TIME DATA TRANSMISSION
Abstract:
An example method includes introducing a downhole tool string into a main wellbore of a multilateral wellbore that includes a lateral wellbore that extends from the main wellbore. The downhole tool string includes a wand and a kickover knuckle joint coupled to the wand. A first measurement is obtained with an orientation measurement device, and an angular orientation of the kickover knuckle joint and the wand is aligned with the lateral wellbore as based on the first measurement. The downhole tool string is then advanced into the lateral wellbore and a second measurement is obtained with the orientation measurement device within the lateral wellbore. The second measurement is compared with known deviation survey measurements corresponding to the lateral wellbore to verifying a location of the downhole tool string in the lateral wellbore. A wellbore stimulation operation is then undertaken with the downhole tool string within the lateral wellbore.
