Broadband interdependent marine seismic source array and method

Abstract From the Canadian patent

A marine seismic source array and method wherein three or more sources are positioned with critical inter-source spacing to produce, when fired in the water, an acoustic pulse whose primary to bubble ratio for a given recording band width is substantially maximized. The sources of the array are adapted and positioned so that each produces when fired a bubble of substantially equal maximum radius. In one preferred embodiment, the array includes four sources positioned approximately at the vertices of a square having side length equal to ?R, where R is the maximum radius of the bubble that would be produced by each source in the array if fired alone. In all embodiments the critical spacing …
