Abstract

Kompletteringsfremgangsmåte til forebygging av formasjonssvekkelse ved komplettering av en brønn ved forankring og aktivering av en piuqg (P) i en valgt posisjon i b.ønnboringen, for avtetting av en valgt del av brønnboringen mot andre deler av denne. Pluggen plasseres i den valgte posisjon i brønnboringen og for- ankres i denne stilling. En tetning i pluggen aktiveres deretter slik at fluid ikke kan passere pluggen. Andre deler av brønnboringen (10) kan deretter drives ved an- dre trykk enn den isolerte del av brønnboringen (12) uten at formasjonen svekkes grunnet tap av brønnfluider til formasjonen.
