Abstract
Oppfinnelsen angår en fremgangsmåte ved nedleggelse av en brann (100) som har opphørt å være til økonomisk nytte. Frem- gangsmåten omfatter høytrykksetting av brønnvæske gjennom produksjonsrøret (11), innbefattet eventuelt ytterligere tilstøt- ende ringrom-kanaler (14,16,18), for å presse væske tilbake inn i reservoaret ved hjelp av et gassmedium, såsom nitrogen. Deretter forsegles produksjonsrøret (11) og eventuelt ringromkanaler (14,16,18) med en egnet forseglingsanordning (124). Dre- nering av øvrige kanaler skjer ved perf- orering inn i det tomrom i produksjons- røret og eventuelt ringromkanaler, som dannes ved hjelp av gassmediet. Deretter følger en avsluttende forsegling av hele brønnen.
