P155 Static Corrections Based on Autopicking and Non–Linear Tomography. Implementation on 2D Data Set D.A. Ilinski* (Inst. of the Phys. of the Earth Russain Acad. Sc.) A.P. Iakovlev (LARGEO) & I.V. Arutuniantz (LARGEO) SUMMARY Commonly used static correction methods require first arrivals picking. Automated picking tools are essential for the increase of seismic processing productivity. We proposed and tested on seismic data a new adaptive first break picking algorithm based on data-derived estimation of first break curves and their variations. The tomography of first breaks for weathering layer velocity calculation became a popular tool for static correction. The alternation of
