Abstract

En fremgangsmåte for å analysere akustiske data omfatter å bestemme lydhastigheten i et formasjonsfluid. Fremgangsmåten innebærer å ta en prøve av fluidet, å sende et akustisk signal inn i fluidet mellom en første og en andre reflekterende overflate. Det blir registrert data som representerer akustiske signaler over tid etter hvert som de blir reflektert fra grenseflatene. En glattet første derivert med hensyn på tid for den kumulative summen av kvadrater (CSS) for de filtrerte amplitudedataene blir bestemt. Denne første deriverte blir kryssko rrelert med sine egne tidsforskjøvede versjoner.
