Shot coding design for popcorn shooting
Ray Abma · 2018
Popcorn shooting in marine seismic survey acquisition is the practice of firing individual air guns in an array nonsimultaneously, as opposed to the conventional practice of firing all the air guns in an array at once. Popcorn shooting should allow better simultaneous source separation, improved removal of the source ghost notch, and decreased peak amplitudes. (Abma and Ross, 2013, Mueller et al. 2015). The signatures created by the Popcorn firing patterns should correlate with each other as minimally as possible to allow better simultaneous shot separation and the best reconstruction of the response to an impulsive source. Optimizing the firing sequences may involve significant computational costs, but the quality of the resulting source codes is likely to be important in getting a conventional image from a Popcorn-like acquisition. This paper examines the alternative methods and various issues in creating air gun source codes.
