Abstract

En fremgangsmåte og et apparat for anvendelse i et borehull omfatter innføring av en verktøystreng til et intervall i borehullet og aktivering av en første komponent i verktøystrengen for å skape en transient underbalansetrykktilstand i borehullintervallet. I tillegg aktiveres en andre komponent i verktøystrengen for å skape en transient overbalanse trykktilstand i borehullintervallet, eller vice versa.
