Infill Decisions Based on Estimated Reflection Amplitudes

P196 INFILL DECISIONS BASED ON ESTIMATED REFLECTION AMPLITUDES 1 SUMMARY A velocity/depth model from a seismic data set was used together with the P1/90 navigation data to estimate the subsurface illumination and the migration amplitudes along key horizons. These simulated migration amplitudes can possibly be generated during the acquisition to assess the need for infill shooting. INTRODUCTION Traditionally coverage specifications are believed to ensure the successful completion of a 3D survey. Since there is less control over the lateral position of the tail of the streamer than the front-end specifications for the large offsets are normally looser. These specifications are
