Abstract

Den foreliggende oppfinnelsen tilveiebringer en fremgangsmåte til å bestemme en egenskap ved en jordformasjon ved å benytte et akustisk loggeverktøy på en bunnhullsstreng (BHA) i et borehull i en jordformasjon. Minst en sender blir benyttet i det akustiske loggeverktøyet for å generere akustiske signaler inn i formasjonen på en første dybde i BHA'en. En flerfoldighet av mottagere blir benyttet på loggeverktøyet for mottak av signaler antyder noe om en parameter av interesse. Flerfoldigheten av mottagere er spredt fra hverandre aksialt fra den minst ene senderen. Målingene gjentas på minst en tilleggsdybde i BHA'en. Signalene på den første dybden og etterfølgende tilleggsdybder blir sortert inn i minst en av (i) en felles mottagersamler, (ii) en felles forskyvningssamler og (iii) en felles midtpunktsamler, hvilket resulterer i omsorterte signaler. De omsorterte signalene blir prosessert for å tilveiebringe parameteren av interesse. Flerfoldigheten av mottagere kan også segmenteres i asimut rundt BHA's akse.
