Abstract
Methods, systems, and devices related to downhole wellbore operations, such as drilling and completing wells in an earth formation, include a laser device. A first portion of a subterranean formation can be characterized, the first portion being at a first location. A first orientation of an aperture can be selected based on the characteristics of the first portion of the subterranean formation. A laser beam can be used to create the aperture having the first orientation. A second portion of the subterranean formation can be characterized, the second portion being at a second location different from the first location. A second orientation, different from the first orientation, can be selected based on the characteristics of the second portion of the subterranean formation. The laser beam can be moved to the second location and can be used to form the aperture having the second orientation.
