Abstract: Computing systems, methods, and computer-readable media for parallel processing an electronic representation of an approximation of a seismic wavefield while preserving spectral properties is presented. The technique may include obtaining, by at least one electronic processor, data representing a seismic wavefield, identifying a plurality of conical supports for the seismic wavefield, deriving, using at least one electronic processor, a plurality of kernels from the plurality of conical supports, decomposing, in parallel, a representation of the measured seismic wavefield in terms of the plurality of kernels to obtain a decomposition, where each of a plurality of kernels is processed by a different electronic processor, removing from the decomposition at least one kernel to remove an unwanted portion of the seismic wavefield, obtaining, based on the decomposition, an approximation of the seismic wavefield, and outputting the approximation of the seismic wavefield.

Abstract: Computing systems, computer-readable media, and methods for calculating traveltime in a model. The method includes receiving a model of a subterranean domain including an anisotropic media, with the model including a grid having gridpoints representing locations in the domain and a source location. The method also includes defining an eikonal equation for calculating a traveltime from the source location, through the anisotropic media, to at least one of the gridpoints, and separating the eikonal equation into a first equation and a second equation. The method further includes iteratively solving the first equation using a processor, such that a first traveltime solution is determined, and numerically evaluating the second equation based on the first traveltime solution.

Abstract: At least one dip is determined using an estimator for the at least one dip based on measured multicomponent survey data. At least one wavefield for the at least one dip is estimated using a processing technique that employs matching pursuit.
