Paper presented at the 2018 SEG International Exposition and Annual Meeting, October 14–19, 2018
Paper Number: SEG-2018-2995074
... ABSTRACT PS converted-wave seismic data is beneficial in many ways, including situations where images are distorted by the presence of shallow gas, and for obtaining more accurate estimates of density and shear impedance using seismic inversion. However, processing both PP and PS data...

... processing. Conventional 3C velocity and image are generally computed in different time scales; PP wave is processed with PP time scale and PS wave with PS time scale. PP and PS wave data are basically processed separately causing errors in horizon calibration between PP and PS waves. Joint inversion of PP...

The real data processing in Block SNL from Sichuan Basin shows that the proposed approach realizes a pretty registration between PP-wave and PS-wave image volumes, and effectively improves the precision of joint multi-wave inversion. Therefore, the feasibility of multi-wave non-rigid matching...

... requires a higher level of care compared to PP-waves alone since the two wave-modes need to be acquired, processed and merged properly. This has diminished the use of PS-waves in the past. However, modern acquisition and processing on land and offshore data make this technology quantitatively more accurate...
