Optimising slip-sweep for high-productivity Vibroseis coal surveys.

The increased scale of 3D seismic surveys in the Australian Coal industry has necessitated the use of high-production slip-sweep surveys. A method is provided which provides a quantitative visualisation of harmonic noise expected for different slip parameters. This provides a practical tool for planning optimal survey parameters. Noise conditions must be seriously considered in survey planning. In areas of good data quality, and with specialised data processing, more aggressive slip times may be possible in future coal-scale slip-sweep surveys. However, in noisy situations a more conservative approach is needed.
