Abstract

En metode for undervanns intervensjonsoperasjoner muliggjør at trykkstyring kan oppnås ved overflaten mens borehullfluidstyring utøves ved havbunnen. Et ettergivende føringsrør (22) strekker seg mellom en undervanns brønninstallasjon (24) og en overflatelokalitet, som for eksempel et overflateintervensjonsfartøy (26). Et bufferfluid (32) anbringes i det ettergivende føringsrør (22) for å opprettholde borehullfluidene nær havbunnen. Bufferfluidet (32) muliggjør også at trykkstyring over bufferfluidet (32) og borehullfluidet kan utføres fra overflaten. I tillegg kan en fleksibel transportstreng ("conveyance") anvendes for å bevege intervensjonsverktøy gjennom det ettergivende føringsrør (22). 1
