Abstract

A technique enables measuring of the actual firing sequence times in a seismic survey application. The actual firing sequence times are then employed in simultaneous source resolution methods. For example, simultaneous seismic sources may be deployed in a survey region. The seismic sources are then fired, and the actual firing times are determined and recorded for use in optimizing the seismic survey.
