Title:
SYSTEM AND METHOD FOR DYNAMICALLY ADJUSTING THE CENTER OF GRAVITY OF A PERFORATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/104634
Kind Code:
A3
Abstract:
A perforating apparatus (100) used to perforate a subterranean well. The perforating apparatus (100) includes a generally tubular gun carrier (106) and a charge holder (104) rotatably mounted within the gun carrier (106). At least one shaped charge (102) is mounted in the charge holder (104) and is operable to perforate the well upon detonation. A dynamically adjustable weight system (124) is operably associated to the charge holder (104). The dynamically adjustable weight system (124) is operable to adjust the center of gravity (120) of the charge holder (104) such that gravity will cause the charge holder (104) 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.
