Abstract

En oppløselig frigjøringsmekanisme (800) for å tillate en bevegelig skjøt (100) å bli kjørt ned i et brønnhull i en låst stilling for å oppta full integritet hva angår trykk- og strekkbelastning. Skjøten (100) blir frigjort gjennom eksponering for kausliske brønnfluider for å oppta fluktasjoner i trykk- og strekkrefter i en brønnformasjon.
