Patching and micropatching in seismic data interpolation

ABSTRACT

I interpolate CMP gathers with PEFs arranged on a dense, radial grid. The radial grid facilitates preconditioning by radial smoothing, and enables the use of relatively large grid cells, which we refer to as micropatches. Even when the micropatches contain enough data samples that the PEF calculation problem appears overdetermined, radial smoothing still noticeably improves the interpolation, particularly on noisy data.
