Abstract: A perforating apparatus (190) used to perforate a subterranean well. The perforating apparatus (190) includes a generally tubular gun carrier (106) and a charge holder (192) rotatably mounted within the gun carrier (106). At least one shaped charge (102) is mounted in the charge holder (192) and is operable to perforate the well upon detonation. A dynamically adjustable weight system (194) including a plurality malleable weight members (196) is operably associated to the charge holder (192). The dynamically adjustable weight system (194) is operable to adjust the center of gravity (120) of the charge holder (192) such that gravity will cause the charge holder (192) to rotate within the gun carrier (106) to position the at least one shaped charge (102) in a desired circumferential direction relative to the well prior to perforating.

Abstract: A perforating apparatus (240) used to perforate a subterranean well. The perforating apparatus (240) includes a generally tubular gun carrier (106) and a charge holder (242) rotatably mounted within the gun carrier (106). At least one shaped charge (246) is mounted in the charge holder (242) and is operable to perforate the well upon detonation. A dynamically adjustable weight system including a weight tube (250) that is selectively rotatable relative to the charge holder (242) is operable to adjust the center of gravity (120) of the charge holder (242) such that gravity will cause the charge holder (242) to rotate within the gun carrier (106) to position the at least one shaped charge (246) in a desired circumferential direction relative to the well prior to perforating.
