    Abstract: Method for acquiring seismic data is described. The method includes determining a non-uniform optimal sampling design that includes a compressive sensing sampling grid. Placing a plurality of source lines or receiver lines at a non-uniform optimal line interval. Placing a plurality of receivers or nodes at a non-uniform optimal receiver interval. Towing a plurality of streamers attached to a vessel, wherein the plurality of streamers is spaced apart at non-uniform optimal intervals based on the compressive sensing sampling grid. Firing a plurality of shots from one or more seismic sources at non-uniform optimal shot intervals. Acquiring seismic data via the plurality of receivers or nodes.

    Abstract: Systems and methods for generating seismic signal include using a conventional airgun array and specifically detunes the timing of the array so individual airguns are not fired at the same time and with their interacting bubbles form a unique composite pulse that can be separated by various means out of a seismic record to form the shotpoint. The advantage of this approach is a lower overall noise envelope in the water minimizing impact on the marine mammals and it allows multiple arrays to be fired in close spatial and timing proximity with minimal to no interference.

    Abstract: Methods and systems are provided for acquiring seismic data in a marine environment using survey paths following a series of linked curved paths so as to obtain multi-azimuthal data over a sub-surface target. Marine vessels towing multiple seismic streamers may be configured to travel substantially along a series of linked deviated paths or a series of linked curved paths. Sources may be excited to introduce acoustic wave energy in the marine environment and into the subsea region. The acoustic wave energy then reflects and refracts from the subsea region to form reflected and refracted wave energy, which is detected by seismic receivers spaced along the streamers. The detected seismic data is then interpreted to reveal seismic information representative of the surveyed subsea region. Other enhancements include configuring the streamers in a flared configuration, where the lateral spacing increases rearwardly over the length of the seismic streamers.
