Abstract
Det offentliggjøres en prosess for sammenstilling av et laderør for en perforeringskanon til bruk i et perforeringssystem. Ved en første lokalisering, eksempelvis et verksted, som ikke er den lokalisering hvor perforeringsoperasjoner vil bli gjennomført, blir laderøret fullstendig sammenstilt. Det fullstendig sammenstilte laderør blir deretter transportert til en annen lokalisering hvor perforeringsoperasjoner skal gjennomføres. I en utførelse blir en RF-sikker tenner, kabling, en detonerende lunte og en flerhet av rettede sprengladninger installert i laderøret ved en første lokalisering. De RF-sikre tennere kan omfatte en tenner med eksploderende folie eller en tråd for en eksploderende bro. En prosess for sammenstilling av et laderør for en enkeltskudds perforeringskanon offentliggjøres også.
