Abstract
A self-orienting perforating gun includes an outer housing having a throughbore, a charge carrier positioned in the throughbore of the outer housing, a hub secured directly or indirectly to the outer housing, a bearing secured to each carrier end of the charge carrier wherein the bearing overlies the hub to provide a rotatable relationship between the hub and the charge carrier about a rotational axis within the outer housing, and an eccentric weight coupled to the charge carrier applying an off-axis orienting force to the charge carrier for urging the charge carrier to rotate about the rotational axis toward a predefined orientation relative to the direction of gravity.
