Abstract

Sammendrag En fremgangsmåte for å bestemme formasjonsresistivitetsanisotropi i nærheten av et brønnhull er beskrevet. Fremgangsmåten ifølge den foreliggende oppfinnelse utvider effektivt det dynamiske området til den eksisterende brønnloggingsservice for flerkomponentinduksjonsverktøyet, noe som tillater bruk av denne service i brønner boret med ledende WBM-systemer. En sekvensiell inverteringsbehandling av galvanisk gruppelaterallogg- HDLL/MLL-data eller DLL/MLL og multikomponent induksjonslogge- (3DEX SM) data blir benyttet. Formasjonsresistivitetsstrukturen til omgivelsene nær brønnhullet bestemmes ved å bruke de galvaniske målingene fra gruppelateralloggverktøyet. Formasjonsresistivitetsanisotropien til den uforstyrrede sonen bestemmes ved å bruke resultatet fra inverteringen av de galvaniske gruppedata og inverteringen av målinger fra det flerkomponente induksjonsverktøyet.
