Abstract

Fremgangsmåter og systemer er tilveiebrakt for nedihullsanalyse av formasjonsfluider ved utleding av differensielle fluidegenskaper og tiknyttet usikkerhet i de predikerte fluidegenskaper basert på nedihullsdata som er mindre sensitive overfor systematiske feil i målinger, og generering av svarprodukter av interesse basert på differansene i fluidegenskapene. Målte data brukes til å beregne nivåer av kontaminasjon i nedihullsfluider ved bruk av f.eks. en algoritme for overvåking av kontaminasjon med oljebasert slam. Fluidegenskaper predikeres for fluidene og usikkerheter i predikerte fluidegenskaper utledes. En statistisk ramme er tilveiebrakt for sammenligning av fluidene for å generere robuste, sanntids svarprodukter som vedrører formasjonsfluidene og reservoarer for disse. Systematiske feil i målte data reduseres eller elimineres ved hjelp av foretrukne prøvetakingsprosedyrer.
