Abstract
According to some embodiments, a system is presented for orienting one or more shaped charge within a well. For example, a perforating gun assembly may include a housing and an orienting internal assembly configured to be disposed within a longitudinal bore of the housing. In some embodiments, the orienting internal assembly may include at least one shaped charge holder or charge tube, a rotation support system, and a detonator holder and/or a detonator. The rotation support system may be configured so that the detonator holder and/or detonator rotate together as a whole with the at least one shaped charge holder or charge tube. In some embodiments, the rotation support system may include at least one bearing assembly, a plurality of rollers, or combinations thereof. Some embodiments may be configured for gravitational orientation.
