Abstract
A system and method of processing seismic data obtained using a plurality of towed single-component receivers in a marine environment is described, the towed single-component receivers configured to measure compressional P waves. The method comprises retrieving seismic data from a storage device, the seismic data comprising P-P data and shear mode data, wherein the P-P data and shear mode data were both received at the towed single-component receivers configured to measure compressional P waves to generate the seismic data. The method further comprises processing the seismic data to extract SV-P shear mode data and generating shear mode image data based on the extracted shear mode data.
Claims6
A system for transferring processed seismic data, comprising:
- one or more geophones configured to receive reflections of seismic waves and to record direct shear wave mode data based on the seismic waves and representing seismic waves which were provided as shear waves directly at a point of application of either a vertical force source or a vertical force P wave from a remote vertical force source;
- a processing circuit configured to receive the direct shear wave mode data and to process the data to generate direct SV and direct SH images;
- and
- a memory device, wherein the processing circuit is configured to transfer the processed seismic data to the memory device.
