DEVICE AND METHOD FOR DEBLENDING SIMULTANEOUS SHOOTING DATA USING AN ITERATIVE APPROACH |
| 摘要 |
A device, medium and method for deblending seismic data associated with a subsurface of the earth. The method includes a step of receiving seismic data S recorded with one or more seismic receivers, wherein the seismic data S includes shot recordings generated by first and second source arrays that are simultaneously actuated; a step of detecting incoherent energy of the seismic data S using a median filter; a step of replacing incoherent parts of the seismic data with a projection filter to obtain deblended data for one of the two or more source arrays; and a step of generating in a computing device an image of the subsurface based on the deblended data. |

1. A method for deblending seismic data associated with a subsurface of the earth, the method comprising:
receiving seismic data S recorded with one or more seismic receivers, wherein the seismic data S includes shot recordings generated by first and second source arrays that are simultaneously actuated; detecting incoherent energy of the seismic data S using a median filter; replacing incoherent parts of the seismic data with a projection filter to obtain deblended data for one of the two or more source arrays; and generating in a computing device an image of the subsurface based on the deblended data. |
