Abstract

Fremgangsmåte for å aktivere et verktøy (800) i en nedihulls streng omfatter å anvende en strømningsrestriksjon, som for eksempel en tilbakeslagsventil (912) som gir mindre restriksjon mot fluidstrømning i den normale retning for å indusere en omvendt trykkforskjell for å tillate aktivering av verktøyet (800).
