Acquisition Geometries For Model-driven Interferometric Ground-roll Removal

David Halliday WesternGeco Summary Model approach that takes advantage of a modified seismic interferometry t scattered ground roll from land was data and a novel 2D acquisition geometry. In this abstract we review the existing applications shortcomings of the application to 3D data. We then consider better application Introduction Interferometric on the cross observed at a pair of receiver locations due to a number of appropriately placed sources (Halliday et al., 2010). The result of this correlation and summation process is an estimate of the wavefield at one receiver as if a source had been placed at the ot process can be configured such that the result is dominated by ground roll. Provided located close to a receiver, the resulting estimates can be adaptively subtracted from sourc receiver records. In this abstract, we consider a modification to interferometric input to interferometry by a model of the direct ground roll (Halliday, 2010
