Abstract: Presented are methods and a system for efficiently acquiring seismic data based on a virtual seismic spread. A streamer vessel and a source vessel are used in combination and in a specific spatial arrangement collect seismic data. The source arrays can be fired simultaneously, creating blended seismic data that is separated with a deblending algorithm or sequentially to collect seismic data directly. The virtual seismic spread can be configured to reduce survey time or decrease capital costs and health safety and environment exposure based on the size of the streamer array towed by the streamer vessel.

Abstract: Methods and systems for performing a single pass multi-density seismic acquisition are described. A single pass multi-density seismic acquisition includes a plurality of different length streamers towed by one or more streamer vessels. The different length streamers are configured to provide different streamer (receiver) density zones from a highest density to lowest density from the least offset to the greatest offset of the streamers. The different density zones provide for optimized data associated with multiples rejection, imaging and model building/full waveform inversion.

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.
