Abstract

Fremgangsmåte for å motevirke at en ventils (2, 4) funksjonsdyktighet reduseres ved sementering av et rør (1) i et borehull (6) i grunnen, og hvor ventilen (2, 4) i det minste delvis innhylles i et nedbrytbart eller av et i det minste av reservoarfluid eller beskyttende fluid gjennomstrømbart materiale (12, 20).
