Abstract
A perforating gun is disclosed with shaped charges at a preferential orientation. An example includes a gun body and a charge carrier disposed within the gun body. The charge carrier defines a longitudinal carrier axis and has a plurality of axially-spaced charge mounting locations. A plurality of charges are each pivotally mounted to the charge carrier at one of the respective charge mounting locations about a charge pivot axis transverse to the longitudinal carrier axis. The charges may preferentially align in response to gravity so their orientation remains constant throughout a range of inclination of the wellbore.
