F017 WAVE-FIELD BASED NEAR-SURFACE CORRECTIONS FOR LAND DATA XANDER CAMPMAN 1 GÉRARD HERMAN 2 1 and EVERHARD MUYZERT 3 1 Department of Applied Mathematics Delft University of Technology P.O. Box 5031 2600 GA Delft The Netherlands 2 Shell International E&P 3 Schlumberger Cambridge Research Summary When traveling through the overburden upcoming body waves can excite scattered surface waves at near-surface heterogeneities. These scattered surface waves interfere with reflections degrading their continuity. Using a multi channel and wave-field-based imaging method we suppress scattered surface waves from a shot record containing a significant amount of near-surface scattering. Continuity is improved and reflections
