The present invention provides method of interpolating spatially aliased seismic data. This method produces high resolution interpolated data based on a locally planar model of reflection events using a two dimensional power diversity slant stack process that transforms the data from the t-x-y domain to t-xslope-yslope domain. The present invention further provides an improved technique for the 3D interpolation of aliased events and is applicable to the interpolation of 2D seismic data.

Interpolation of aliased seismic traces

A method for attenuating coherent and incoherent noise in seismic signal data is provided. Seismic signal data is transformed from a time-space domain using a Radon-transform domain. In the Radon-transform domain, coherent noise is attenuated by muting and incoherent noise is attenuated by diversity stacking. Data remaining in the Radon-transform domain in transformed back to the time-space domain by an inverse Radon transform.
