Abstract

Den foreliggende oppfinnelsen vedrører fremgangsmåter og utstyr for gjenvinningsbruk av et brønnhull under omstendigheter hvor brønnhullene har blitt blokkert av nedihullsutstyr. Oppfinnelsen tilveiebringer en fremgangsmåte innbefattende trinnene å adskille, i en utløsningskobling, en del av utstyret fra en fastkilt del (6) av utstyret, å kjøre den adskilte delen av utstyret opphulls og ut av brønnhullet (100), å kjøre en deflektorsammenstilling (60) nedihulls inn i brønnhullet (100), og å avbøye et freseverktøy (64) fra brønnhullet og inn i den omkransende formasjonen. Fremgangsmåten er kjennetegnet ved å begrense relativ bevegelse mellom defiektorsammenstillingen (60) og brønnhullet (1 00) ved å koble, forut for avbøying av freseverktøyet (64), defiektorsammenstillingen (60) til den fastkilte delen (6) av utstyret.
