Abstract
A technique facilitates slowness estimation in accordance with dispersion information in a sonic logging tool. The technique may be used for processing dispersive waveforms in real-time. In this embodiment, the technique utilizes a sonic transmitter and a sonic receiver array in the logging tool. The technique also includes use of a memory and a processor mounted in the logging tool, for converting dispersive waveforms into slowness of the formation and/or fluid in accordance with dispersion information stored in the memory. Additionally, the technique may utilize a telemetry system for sending the formation slowness data and/or quality control indicators to the surface.
