System and method for isolating signal in seismic data |
摘要 |
<p>A system and method for isolating signal in seismic data representative of a subsurface region of interest including receiving a seismic dataset representative of seismic signal and seismic noise and a seismic data guide; transforming the seismic dataset and the seismic data guide into a domain wherein the seismic data have a sparse or compressible representation to create a first set and a second set of representative coefficients; comparing the first set of representative coefficients to the second set of representative coefficients to identify and select desirable members of the first set of representative coefficients that are within a defined threshold of the second set of representative coefficients to create an improved first set of representative coefficients; and performing an inverse transform of the improved first set of representative coefficients to generate a modified seismic dataset.</p> |
