Processing Seismic Reflection Data of La Bajada Fault Ryan Lester
Outline • Acquisition • Processing • Final image
Raw Data Obs.notes Geom Rec.loc Kill traces Sourceloc AGC Freq. Filter CMP sort No exciting CMP sort picture. Sorry. NMO CVstack
Velocity Function CVstack Show examples of CVS
Velocity Function CMPsort NMO CMP Stack
A few other things we played with • Predictive Deconvolution • Eliminates multiples • Surgical muting • Eliminate groundroll in data • FK filtering • Eliminate groundroll and other non-random noise in data • Coherency filtering (post stack) • Enhance signal
Final stack based on CV stacks Final stack based on refraction velocity
