Abstract
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.

A self-orienting internal assembly of a perforating gun system having a perforating gun housing, the self-orienting internal assembly comprising:
- a shaped charge;
- and
- a detonator coupled to the shaped charge, wherein the shaped charge and the detonator are configured to rotate together relative to the perforating gun housing.
A perforating gun assembly, comprising:
- a housing defining a longitudinal bore;
- a shaped charge rotatably supported in the longitudinal bore of the housing;
- and
- a detonator in a fixed rotational relationship with the shaped charge, wherein the shaped charge and the detonator are configured to rotate relative to the housing about a central longitudinal axis defined by the housing.
