Abstract

Systems and methods for acquiring blended and unblended seismic data during a single seismic survey. The blended and unblended seismic data is generated with a plurality of sources that are fired in a dedicated sequence. The sequence involves firing all the sources at a first time, advancing the sources along a given path, firing only a first source at a second time, later than the first time, advancing the sources, firing again all the sources at a third time, later than the second time, advancing the sources, firing only a second source at a fourth time, later than the third time, and so on until a desired subsurface is fully surveyed.
