Patent ID: 8554483

Claim:
A method of modifying processing results during a subterranean formation drilling operation, comprising: processing, with one or more processing modules, measurements associated with the subterranean formation obtained while drilling and a plurality of parameters to generate first results; processing, with the one or more processing modules, measurements associated with the subterranean formation obtained while drilling is temporarily suspended and the plurality of parameters to generate second results; comparing, with the one or more processing modules, the first and second results; in response to the comparison of the first and second results, modifying, with the one or more processing modules, the first results based on the second results to improve a quality of the first results, wherein modifying the first results based on the second results comprises applying a recursive filter to at least the second results and identifying one or more slowness time coherence peaks within the first results as being associated with one or more slowness time coherence peaks in the second results, associated with noise, or not associated with noise; and updating, with the one or more processing modules, the plurality of parameters based on the second results.
