Technical Abstract

De-coupling Residual Statics and Velocity Picking

Back to Technical Content
We introduce a method for separating residual statics and NMO velocities by maximising sparsity in tau-v and tau-p domains. Surface Consistent statics are computed without a-priori knowledge about velocities needed for NMO corrections. In such way static time shifts will not be applied to compensate velocity errors. The new approach provides accurate focusing and positioning of the reflectors without needs to iterate updates of residual statics and velocities.
