Technical Abstract

Detection and correction of surface- and acquisition-related inconsistencies: A case study in land vibrator data

Back to Technical Content
Analyzing seismic amplitude trends requires stability of the seismic wavelet in both amplitude and phase. Unfortunately, in land acquisition, the filter applied as energy travels through the near-surface can have a dramatic impact on both. Here, we will extend previous work on proposing detailed QC methods for surface-consistent deconvolution of land dynamite data to land vibrator data. In the process, we uncover and attenuate an apparent acquisition abnormality, producing seismic data more amenable to sensitive post-migration analysis and inversion.
