Abstract
Utførelsesformer av den foreliggende oppfinnelse inkluderer metoder og apparatur for dynamisk å kontrollere trykk i et borehull (1515) under dannelse av dette. l et aspekt anvendes ett eller flere trykkontrollapparater for å opprettholde ønsket trykk inne i borehullet (1515) under boring av borehullet (1515). l et ytterligere aspekt kontrolleres trykket dynamisk under boring under anvendelse av skum (M) for å opprettholde et hovedsakelig homogent skumstrømningsregime inne i borehullringrommet (A) for å transportere borekaks fra borehullet (1515) til overflaten (1505).
