Claim 7:
8. A method for removing a guided wave noise in a frequency-domain, comprising:
recording one or more acoustic signals with one or more receivers disposed on an acoustic logging tool at a first location, wherein the one or more acoustic signals are raw data;
determining a slowness range;
estimating a downward guided wave noise and an upward guided wave noise;
identifying a slowness that is a highest stacked amplitude;
estimating the downward guided wave noise with the slowness;
estimating an upward guided wave noise with the slowness;
subtracting the downward guided wave noise and the upward guided wave noise from the raw data
moving the acoustic logging tool to a second location, wherein the second location is determined by the one or more acoustic signals.
