The patent US12044817B2 outlines a method for evaluating the performance of non-impulsive sources within a source array, focusing on their geometrical distribution and the resulting energy outputs. The process begins with a machine receiving a proposed geometrical distribution for two non-impulsive sources. It then conducts a near-field-to-notional computation to generate computed outputs for each source. The method assesses whether the energy residue from one source, relative to the other, exceeds a predetermined threshold. If both sources meet the residue criteria, the method allows for further actions, such as conducting a marine survey or generating a new geometrical distribution to optimize the arrangement of the sources.

Additionally, the claims detail various configurations for the sources, including the possibility of incorporating a third non-impulsive source and adjusting the distances between sources to minimize energy residue. The method also includes provisions for determining the geometrical positions of receivers associated with each source, ensuring they are equidistant from the sources. Ultimately, the method culminates in the creation of a geophysical data product, which involves recording the obtained geophysical data on machine-readable media, thereby facilitating further analysis and application in geophysical studies.
