Ground-roll characterization: Cold Lake 3-D seismic example

Robert James Ferguson

A procedure to characterize regional variation of ground-roll for 3-D seismic data is outlined. Characterization is done in both the azimuth-offset domain and the (f,k) domain. Examples show that ground-roll present on the Cold Lake 3-D data set has very little azimuthal variance, and has a dip of 400 m/s f-k space.
