Abstract
Det beskrives en fremgangsmåte for boring av en brønnboring under en sementert foring ved hjelp av én bor-tur. Fremgangsmåten innbefatter senking av en borkrone ned i en foring som er sementert på plass i brønnboringen. Foringen innbefatter deri anordnet flottørutstyr. Borkronen roteres i foringen over flottørutstyret på en slik måte at borkronen ekspanderes. radielt utover til en diameter som er større enn innerdiameteren. i foringen. Flottørutstyret, som kan være en øwe eller nedre. flottørsko eller en hvilken som helst annen type flottørutstyr,. innbefatter et ytrehus med en dermed forbundet ventil. Det. ytre hus består av et utborbart materiale. Den borkrone som. benyttes for boring av brønnboringen kan således begynne sin. boringsoperasjon over flottørutstyret og deretter bore ut en. brønnboring under foringen med en diameter som er større enn. innerdiameteren i foringen.
