FIELD: physics.
SUBSTANCE: method for making acoustic logging measurements includes grouping received acoustic waveforms into one of a plurality of groups, each said representative group corresponding to certain measured borehole condition parameters (e.g., a range of measured deviation values and/or a range of measured azimuth angles). The acoustic waveforms stored in at least one of the groups are stacked so as to obtain an averaged waveform. The averaged waveform may be further processed, for example, via a semblance algorithm to obtain at least one acoustic wave slowness.
EFFECT: high accuracy of logging data.
