Abstract

Fremgangsmåter og systemer for å bestemme den horisontale resistiviteten, vertikal resistivitet og relativ inklinasjonsvinkel for anisotropiske bakkeformasjoner er beskrevet. Noen av de fremlagte fremgangsmåter og systemer måler sinusaktig variasjon av asimutisk sensitivitetsresistivitetsloggeverktøymålinger, bestemmer parametere som representerer de sinusaktige variasjonene og utføre inversjon basert på de sinusaktige parameterne. Når utført på denne måten vil inversjonsprosessen kunne gi mer nøyaktige og konsistente resistivitets- og inklinasjonsvinkelestimater. De sinusaktige parameterne har foretrukket formen av gjennomsnitt og topp-til-topp målinger, men kan også ha andre former. Videre vil bruk av slike sinusaktige parametere muliggjøre en pakket representasjon av resistivitetsloggeverktøymålinger, som muliggjør signifikant mer effektiv kommunikasjon og lagring av disse målingene. De pakkede representasjonene fortsetter å muliggjøre retningsgrensedeteksjon og geostyring.
