Three different methodologies for estimating compressional (P) and shear (S) wave reflectivities were examined using the Mobil North Sea data set. All three approaches involved estimating intercept and slope values from the seismic data and then converting these intercept and slope estimates into P- and S-wave reflectivity. The first approach used the traditional method of estimating intercept and slope from unmigrated NMO corrected CMP gathers. The second also estimated intercept and slope from NMO corrected CMP gathers, but the estimation was performed after common-offset time migration. The third technique inverts for intercept and...

Comparison of Seismic Inversion Methods on a Single Real Data Set
Papers in this volume explore the potential of a variety of seismic inversion methods applied to the same data set. They cover a wide range of topics, including effects of rock properties on seismic response, preparation of seismic data for AVO analysis, and a variety of AVO and inversion methods. The papers are an extension of a 1994 SEG postconvention workshop.
