Title
(EN) PROCESSING SEISMIC DATA IN COMMON GROUP-CENTER GATHERS
(FR) TRAITEMENT DE DONNÉES SISMIQUES EN COLLECTIONS CENTRÉES-GROUPÉES COMMUNES
Abstract
(EN) A method for processing seismic data. The method includes plotting a travel-time curve and one or more actual times that each seismic receiver receives one or more seismograms on a graph. The travel-time curve represents an approximate time that each seismic receiver in a seismic survey area receives the seismograms. The method may further include determining a residual static shift for each seismogram and using the residual static shift to estimate a time shift correction. The residual static shift represents a difference between an actual time in which a seismic receiver received a seismogram and a time on the travel-time curve that corresponds to the actual time. The time shift correction corrects a timing error in the time indicated by the travel-time curve.
(FR) L’invention concerne un procédé de traitement de données sismiques. Le procédé comprend le tracé d’une courbe temps-distance et d’un ou de plusieurs temps réels auxquels chaque capteur sismique reçoit un ou plusieurs séismogrammes sur un graphique. La courbe temps-distance représente un temps approché auquel chaque capteur sismique d’une zone d’étude sismique reçoit les séismogrammes. Le procédé peut en outre comprendre la détermination d’un décalage statique résiduel pour chaque séismogramme et l’utilisation du décalage statique résiduel pour estimer une correction de décalage temporel. Le décalage statique résiduel représente la différence entre un temps réel pendant lequel un capteur sismique reçoit un séismogramme et un temps sur la courbe temps-distance qui correspond au temps réel. La correction de décalage temporel corrige une erreur de minutage dans le temps indiqué par la courbe temps-distance.
