... offshore. By. 1974 62 % of all geophysical survey ships were equipped with air guns [ 1]. More sophisticated processing systems have led to an increased demand on seismic energy sources, which means: 1. Signal amplitude must be large enough to pick reflections from deep horizons. 2. Signal characteristic...

... quantitative studies of air gun and air gun array designs in ways that are difficult, or even impossible, to do by field experiments. Our findings using the model include the following: (1) The strength of an air gun is roughly propor- tional to the square root of the port area. as expected. We show, however...

... the primary energy from the air-gun source. In deep seismic profiling, large air-guns are often used without attempting to attenuate either the bubble pulse or the primary pulse. Therefore, to optimize the low frequency energy, the air-gun array could be designed in a way that preserves the low...

Now that more powerful gun clusters and arrays are being used, these larger air-gun sources must be positioned further away from the ship s side.
