<p>One aspect of the invention relates to a method and system of towing 200 a plurality of air guns in a body of water wherein the largest of the guns has a bubble period. A bubble test is performed 202 on a first gun and a second gun at first and second times respectively. A delay 204 between the first and second time is at least as long as the bubble period and at most as long as twenty times the bubble period. In another aspect, a bubble test includes beginning a short record by initiating data recording at a sensor and during the short record firing two seismic guns with a time delay. After firing the second gun, the shot record is ended by stopping the data recording at the sensor. The firing sequence may include a progression form an aft-most portion of the plurality of air guns to the forward-most portion. According to some embodiments of these techniques, a firing sequence for testing the air guns may be determined that reduces the amount of interaction between firings. Further, firing time delays may also be determined in order to further reduce the interactions. Accordingly, a test of an array of air guns may be completed relatively quickly.</p> |
