Patent ID: 8209126

Claim:
A computer-implemented method for processing data, comprising: accepting, by a computer, a first collection of traces corresponding to signals received over time due to reflection of seismic waves from subsurface structures; defining, by the computer, a Radon transform having a summation path which is a function of at least three parameters, including a plurality of wavefront parameters of the seismic waves; applying the Radon transform to the first collection of traces, for a plurality of values of each of the at least three parameters, so as to convert the first collection into a multidimensional data array, of at least three dimensions, each point in the multidimensional data array is defined as a function of at least three wavefront parameters; processing the multidimensional data array, so as to produce a second collection of traces having an improved imaging quality with respect to the first collection; wherein the wavefront parameters comprise an angular parameter and at least one radius of curvature of a wavefront outgoing from a subsurface reflector, and wherein the angular parameter comprises an emergence angle, and wherein the at least one radius of curvature comprises respective radii of a common reflected element and a common evolute element of the wavefront.
