Abstract

I henhold til et visst aspekt av foreliggende oppfinnelse er det angitt en fremgangsmåte for å evaluere vannmetningsegenskaper. Denne fremgangsmåte kan anvendes på en geologisk formasjon som gjennomtrenges av et borehull og omfatter innsprøytnings-fluid ført inn i formasjonen ved hjelp av en ytre påført prosess utført på borehullet. Denne fremgangsmåte omfatter utførelse av elektromagnetiske induksjonsmålinger som angir resistivitetsverdier for formasjonen. En verdi for total porøsitet for formasjonen blir også utledet. Fremgangsmåten går så ut på å definere fraksjons-volumer for så vel leirebundet vann, fritt vann og ikke-reduserbart vann i formasjonen, hvor volumet av fritt vann tar med injeksjonsfluid som er sprøytet inn i formasjonen. Fremgangsmåten gjelder også fastleggelse av konduktivitetsverdier for så vel leirebundet vann, fritt vann og ikke-reduserbart vann, hvor da konduktiviteten av fritt vann fastlegges ut i fra konduktiviteten av det innsprøytede fluid. Til slutt blir formasjonens vannmetning bestemt ut i fra en sammenheng mellom formasjonens totale porøsitetsverdi og konduktivitetsverdier, samt konduktivitetsverdiene og fraksjonsvolumene for så vel leirebundet vann, fritt vann og ikke-reduserbart vann. Denne sammenheng er fortrinnsvis angitt ved trippelvannligningen.
