Open the CIPO recordAbstract From the Canadian patent
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.
