Abstract
En teknikk muliggjør demping av skadelige krefter som er dannet under perforeringsprosedyrer. Ladninger er montert i en perforeringskanon i en vinkel som eliminerer i det minste enkelte av de skadelige krefter. Ladningene er skråstilt i forhold til en akse i perforeringskanonen, og dette demper de skadelige krefter og reduserer muligheten for skading av perforeringskanonen og annet tilknyttet utstyr under en perforeringsprosedyre.
