Acquisition and Processing of Multi-Source Broadband Marine Seismic Data |
摘要 |
A method and a system of acquiring and processing multi-source broadband marine seismic data in such a way that at least a part of said acquired data is partially or fully de-ghosted on the receiver side and then partially or fully re-assembled to a pre-stack dataset. At least one non-uniformly horizontal streamer is towed and at least two seismic sources emit seismic signals at spaced apart positions. Further presented is a method of processing marine seismic data by using the thus resulting notch diversity in these two (or more) seismic records to de-ghost the dataset, gathering two or more recorded seismic signals having substantially the same source-sensor offset and substantially the same common mid-point at different sensor depths, the sensor depths at least different enough to enable identification of seismic signals originating from ghosting. The gather is de-ghosted, thus obtaining seismic data with significantly broader bandwidth.
