Abstract
Official abstract text for this publication.
Formation evaluation measurements are used to estimate formation lithology. The estimated lithology is used to provide an estimate of acoustic wave slowness. The estimated acoustic wave slowness is used to provide processing parameters for acoustic data that are less sensitive to noise.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of evaluating an earth formation, the method comprising: conveying a carrier into a borehole; acquiring acoustic data indicative of a property of the earth formation using an acoustic device on the carrier; and using a processor to pick an acoustic data set from the acquired acoustic data, wherein the processor picks the acoustic data set, at least in part, based on processing parameters derived from a petrophysical analysis of lithologic data.…
