SYSTEMS AND METHODS FOR RANDOMIZING FIRING TIMES OF SIMULTANEOUS SOURCES IN MARINE SURVEYS

Computational systems and methods for randomizing the order in which multiple sources are fired in simultaneous source acquisition are described. In one aspect, pseudo--randomly shifted time delays are generated for each shot interval of a marine-survey-time line (1301-1304 and 1307-1308). Each shif...

Zusammenfassung:Computational systems and methods for randomizing the order in which multiple sources are fired in simultaneous source acquisition are described. In one aspect, pseudo--randomly shifted time delays are generated for each shot interval of a marine-survey-time line (1301-1304 and 1307-1308). Each shifted time delay is assigned to one or the sources. The sources within each shot interval are fired based on the shifted time delays (1305). (Figure 13)
