Patent 7668043 was granted and assigned to Schlumberger on February, 2010 by the United States Patent and Trademark Office.
Techniques for processing sonic waveform data include processing the data based on an initial set of formation-borehole parameters, to produce initial coherence peak attributes, wherein the processing is performed in a borehole; sending the initial coherence peak attributes uphole via telemetry; and correcting the initial coherence peak attributes, based on a second set of formation-borehole parameters, to produce corrected coherence peak attributes.
