InSite Velocity Module

The Velocity Module analyses ‘active’ data for velocity and amplitude information. Active data is produced from a man-made source such as a shot or a transmitter.

• P and S-wave transmission velocities are calculated from time of flight between source and receiver using the picked arrivals.
• A waveform cross-correlation algorithm allows P and S-wave velocity changes to be calculated precisely between repeated surveys.
• The cross-correlation (CCR) algorithm can be configured to the data quality with various waveform processing functions being applied.
• CCR provides efficient automatic processing of surveys for velocity data resulting in 1000s of surveys being processed automatically.
• Signal amplitude information from the arrivals is also obtained for use in attenuation studies.
