IS-1 STATIC PERTURBATION CORRECTIONS ON SINGLE SENSOR DATA G.J.M. BAETEN 1 L. COMBEE 2 and L. WEST 1 Abstract 1 One of the main determining factors for the quality of land seismic data is the accuracy of the static corrections. Static corrections aim at correcting for time shifts between traces which are principally due to near-surface effects. As far as conventional statics techniques are concerned there are two classes of solutions: • Deterministic statics solutions. For example field statics based on upholes and elevation measurements; refraction statics solutions based on first break picking and assumptions about the layered structure of
