Abstract
A method for determining the effective or apparent firing time of a seismic source. The seismic detectors positioned at known distances from the source, but outside the non-linear acoustic region, are used to detect arrivals of energy from the source. The arrival times and known distances are used to determine effective source firing time which is in turn used to calibrate the source for actual seismic operations.
