P-156 STATICS AND NEAR-FIELD SCATTERING Summary XANDER H. CAMPMAN CH. DWI RIYANTI and GÉRARD C. HERMAN Delft University of Technology Subfaculty of Applied Mathematics Mekelweg 4 2628 CD Delft In seismic data waves scattered at the near surface are a source of deterministic noise. When the scattering occurs near the source or receivers the effect resembles the effect of short-wavelength statics. We present a model study of the near-receiver scattering and find that the effect of such scattering is a complex process involving interfering surface waves. The conventional statics assumption does not hold here. In an attempt to improve processing
