Abstract

En fremgangsmåte ved kjennetegning av skjærbølgeanisotropi i en formasjon omfatter at kryssede dipolbølgeformer oppnås fra et borehull som trenger igjennom formasjonen over et område av dybder og frekvenser, senhet fjernt i feltet bestemmes i en rask og sakte skjærkraftretning ved å bruke et lavfrekvent parti av de kryssede dipolbølgeformer, og senhet nær borehullet bestemmes i de raske og sakte skjærkraftretninger ved å bruke et høyfrekvent parti av de kryssede dipolbølgeformer. Videre omfatter fremgangsmåten at en valgt dybde i formasjonen markeres til å ha iboende anisotropi dersom fjernfeltsenheten i den raske skjærkraftretning er mindre enn fjernfeltsenheten i den sakte skjærkraftretning ved den valgte dybde og senheten nær brønnhullet i den raske skjærkraftretning er mindre enn senheten nær brønnhullet i den sakte skjærkraftretning, mens en valgt dybde i formasjonen markeres til å ha trykkindusert anisotropi dersom fjernfeltsenheten i den raske skjørkraftretning er mindre enn fjernfeltsenheten i den sakte skjærkraftretning ved den valgte dybde og senheten nær brønnhullet i den raske skjærkraftretning er større enn senheten nær brønnhullet i den sakte skjærkraftretning.
