Abstract
Wide-azimuth datasets allow us to incorporate more dimensions into data regularisation. Using a multi-dimensional Fourier transform that handles irregular data we can either output traces on a regular grid or interpolate additional source and receiver lines. This allows us to fill holes more effectively and regularise in the offset and azimuth directions whilst preserving amplitude variation with offset and azimuth (AVO and AVAz). We show how the anti-leakage Fourier transform can be used with four spatial dimensions and use OBC and land data examples to highlight improvement in continuity and accurate reconstruction of missing data.
