Abstract

Et multigruppert selvstående stigerørsystem inkluderer ett eller flere mellomliggende oppdriftskamre konfigurert for å tilveiebringe en oppoverrettet løftekraft på strenger av tilknyttede stigerørsammenstillinger. De mellomliggende kamrene har enten en åpenbunnet eller lukket beholderkonstruksjon. Kamrene kan videre inkludere et hjelpeoppdriftsmateriale konstruert for enten å blandes med eller å inneholde trykksatte fluider injisert inn i kamrene. Det selvstående stigerørsystemet inkluderer videre en nedre stigerørsammenstilling festet til en primærbrønnboringsfikstur. Systemet inkluderer også en øvre stigerørsammenstilling og ett eller flere ytterligere oppdriftskamre anordnet i enten direkte eller indirekte kommunikasjon med hverandre, så vel som med bore-, produksjons- og leteboringsutstyr som påkrevd av de tilknyttede operasjoner.
