Seismic data processing is normally targeted for the recovery of correct relative amplitudes and imaging. The same data may not be best suited for AVO analysis. For inversion/AVO analysis, it is necessary to condition the data accordingly. One of the important steps in the seismic data conditioning is checking for consistency of amplitudes laterally. In onshore data, surface-related geology may affect both acquisition and processing workflows which in turn affect the subsequent analysis using seismic. We present a fast solution for addressing these near-surface effects in partial angle stack seismic using RMS amplitude maps. The resulting seismic is suitable for use in any AVO analysis and Quantitative Interpretation (QI) workflows. The seismic data used as an example is from the Delaware Basin, which is the larger of the two major lobes of the Permian Basin. While there are certainly limitations on when the workflow may be applied, we believe that it is helpful when timeline pressures prohibit a more comprehensive solution.
