Abstract
Method for acquiring seismic data is described. The method includes obtaining undersampled seismic data acquired from a non-uniform sampling grid. Attenuating multiples from the undersampled seismic data.
Claims21
A method of seismic data processing the method comprising:
- acquiring undersampled seismic data from one or more sources and one or more receivers of a seismic survey with a non-uniform sampling grid designed using non-uniform optimal sampling design, the non-uniform sampling grid including at least one of the one or more sources or the one or more receivers positioned with a non-uniform spacing;
- modeling near-angle water bottom reflection data;
- attenuating multiples from the undersampled seismic data;
- and
- generating a seismic image of reservoir structures.
