Title (EN) METHOD FOR WAVEFIELD SEPARATION FOR DUAL-SENSOR DATA USING KIRCHHOFF-TYPE DATUMING AND MIGRATION
(FR) PROCÉDÉ DE SÉPARATION DE CHAMPS D'ONDES POUR DES DONNÉES DE CAPTEUR DOUBLE EN UTILISANT UNE DÉFINITION DE DONNÉES ET UNE MIGRATION DE TYPE KIRCHHOFF
Abstract:
(EN) A first weighted integral operator is applied to dual-sensor data to extrapolate the dual-sensor data to a first position above an acquisition surface, generating extrapolated data. A second weighted integral operator is applied to the extrapolated data to extrapolate the extrapolated data to a second position, generating wavefield separated data. One of the integral operators is applied to a scaled combination of the dual sensor data.
(FR) Un premier opérateur intégral pondéré est appliqué à des données de capteur double pour extrapoler les données de capteur double à une première position au-dessus d'une surface d'acquisition, générant des données extrapolées. Un second opérateur intégral pondéré est appliqué aux données extrapolées pour extrapoler les données extrapolées à une seconde position, générant des données de champs d'ondes séparées. Un des opérateurs intégral est appliqué à une combinaison mise à l'échelle des données de capteur double.
