SYSTEM AND METHOD FOR RANDOMIZING FIRING TIMES OF SEISMIC SOURCES IN MARINE SURVEYS

摘要

Computational systems and methods for randomizing the order in which multiple sources are fired in simultaneous source acquisition are disclosed. In one aspect, pseudo-randomly shifted time delays are generated for each shot interval of a marine-survey-time line. 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.
