Dynamic Statics - Improving Seismic Image on a 3D-9C Survey

Application of innovative Dynamic Statics approach to solving and decoupling statics and velocity allowed for improved seismic image of PP component (pure mode P-wave), SS component (pure mode S-wave). Dynamic Statics algorithm computes statics corrections as pure time shifts on reflected waves and does not require velocity model and first break picking. Converted PS image (C-wave) was obtained automatically and was used as a QC by taking P-wave statics and velocity solution for the source component and S-wave statics and velocity for upgoing (receiver) component. Conventional velocity and first break based statics solution delivered lower quality results on this 3D-9C dataset, characterized by complex near-surface conditions, and C-wave image has never been obtained.
