US12338718 - Orienting perforation gun assembly

A perforating gun assembly that orients one or more shaped charges within a well includes a housing and an orienting internal assembly configured to be disposed within a longitudinal bore of the housing. The orienting internal assembly may include at least one shaped charge holder or charge tube, a rotation support system, 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. The rotation support system may include at least one bearing assembly, a plurality of rollers, or combinations thereof. The orienting internal assembly may be configured for gravitational orientation.
