Abstract:
1. A method, comprising: providing a fixed path along which seismic data are to be acquired; providing a plurality of guns; determining membership of each gun in either a first set of guns or a second set of guns, wherein the first set of guns and the second set of guns have at least one gun in common and wherein the first set of guns has at least one guns not found in the second set of guns; determining a geometric center of the first set of guns and a geometric center of the second set of guns; comparing the fixed path with the geometric center of the first set of guns and the geometric center of the second set of guns during acquisition of the seismic data; selecting one of the first set of guns and the second set of guns to be actuated whose geometric center substantially aligns with the fixed path; and actuating only the selected one of the first set of guns and the second set of guns.
