P154 Velocity-Scanning Statics Corrections Based on Common Offset Data E. Dianliang* (BGP CNPC) Y.Z. Guan (BGP CNPC) & H.R. Yang (BGP CNPC) SUMMARY Based on an analysis of current approaches for computing statics in the process of vibroseis seismic data this paper presented a method which jointly uses uphole survey and common offset data to compute statics corrections. Differing from commonly used model-based or refraction statics corrections and considering the issues suitable for data processing our method fully uses production records and a small amount of uphole survey data to compute LVL (low velocity layer) velocities and buried depths of
