Abstract
A method for separating the unknown contributions of two or more sources from a commonly acquired set of wavefield signals representing a wavefield where the contributions from different sources are both encoded by means of the principles of signal apparition and as well as by means of different source encoding techniques.
Claims18
A method for simultaneous source acquisition and/or separation, comprising:
- obtaining seismic recordings using at least two different simultaneous source acquisition and/or separation methods, wherein at least one of the simultaneous source acquisition and/or separation methods includes performing a signal apparition process;
- separating, using the seismic recordings, wavefields encoded relative to each other in accordance with at least one of the at least two different simultaneous source acquisition and/or separation methods;
- generating a sub-surface representation of structures or Earth media properties from at least one of the separated wavefields;
- and
- outputting the generated sub-surface representation.
