Abstract

Det er frembrakt en fremgangsmåte for komplettering av en olje- og gassbrønn. Perforatorene (10, 11) kan velges blant hvilke som helst kjente eller vanlig benyttede perforatorer, og er typisk anbrakt i en perforeringskanon. Perforatorene innrettes slik at de skjærende stråler (12, 13) og de tilknyttede sjokkbølger konvergerer mot hverandre slik at deres samvirke bevirker øket frakturering av fjellet. De skjærende stråler kan også være slik innrettet at de skjærende stråler bringes til å kollidere og bevirke øket frakturering av fjellet. I en alternativ utførelse av oppfinnelsen er det anordnet en foring (6) for rettet ladning med i det minste to konkave områder, med en geometri som er slik valgt at etter sammenbruddet av foringen dannes flere skjærende stråler, idet disse stråler er konvergerende eller i stand til å kollidere i fjellet.
