Abstract

Hullenhet som omfatter en borkrone, en stabilisert hullutviderenhet beliggende bak borkronen, og en boreenhet. En fremgangsmåte for å bore i en formasjon omfatter anbringelse av en stabilisert hullutviderenhet bak borkronen, anbringelse av en boreenhet bak den stabiliserte hullutviderenheten og rotasjon av borkronen og den stabiliserte hullutviderenheten med boreenheten. En stabilisert hullutvider beliggende mellom en retningsboreenhet og en borkrone omfatter i det minste én armenhet som forløper fra den stabiliserte hullutviderenheten, idet armenheten omfatter et stabilisatorparti og en hullutvider-skjærestruktur.
