First Claim
Patent Images
1. A method of acquiring and processing marine seismic data, said method comprising:
- a) moving multiple seismic receivers through a body of water;
b) simultaneously with step (a), performing a series of periodic seismic sweeps by simultaneously energizing at least two seismic sources and acquiring source seismic data and reflected seismic data;
c) reorganizing said source seismic data and/or said reflected seismic data based on common source-receiver centerpoints from different seismic sweeps, thereby generating reorganized seismic data; and
d) source separating said reorganized seismic data.

13. A method of processing seismic data, said method comprising:
-
a) receiving seismic data including i) encoded source data for multiple sweeps of multiple seismic sources, wherein said multiple sweeps include simultaneous excitation of said multiple seismic sources with said multiple seismic sources being at a substantially different location for each sweep, ii) reflected seismic data acquired by multiple seismic receivers for each of said multiple sweeps; b) reorganizing said reflected seismic data based on common source-receiver centerpoints from different sweeps, thereby generating reorganized reflected seismic data; and c) source separating said reorganized reflected seismic data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
