1. A computer-implemented method for isolating signal in seismic data representative of a subsurface region of interest, the method comprising:
a. receiving, at a computer processor, a seismic dataset representative of seismic signal and seismic noise and a seismic data guide; b. transforming, via the computer processor, the seismic dataset into a domain wherein the seismic dataset has a sparse or compressible representation to create a first set of representative coefficients; c. transforming, via the computer processor, the seismic data guide into a domain wherein the seismic data guide has a sparse or compressible representation to create a second set of representative coefficients; d. comparing, via the computer processor, the first set of representative coefficients to the second set of representative coefficients to identify desirable members of the first set of representative coefficients that are within a defined threshold of the second set of representative coefficients; e. selecting, via the computer processor, the desirable members of the first set of representative coefficients to create an improved first set of representative coefficients; and f. performing, via the computer processor, an inverse transform of the improved first set of representative coefficients to generate a modified seismic dataset. |
