P094 AN APPROXIMATE INTEGRAL REPRESENTATION FOR NEAR-ARRAY (INVERSE) SCATTERING XANDER CAMPMAN 1 CHRISTINA D. RIYANTI 1 and GÉRARD HERMAN 2 1 1 Department of Applied Mathematics Delft University of Technology P.O. Box 5031 2600 GA Delft The Netherlands 2 Shell International E&P Summary We derive an approximate integral representation to model and image near-surface scattering. This formulation forms the basis of a prediction-and-subtraction algorithm to reduce near-surface scattering on seismic data. We investigate how well this approximate equation reconstructs the scattered field obtained by full elastic 3D modeling. The approximate equation characterizes the scattering in the immediate subsurface and allows
