Title (EN) WAVEFIELD SEPARATION USING A GRADIENT SENSOR
(FR) SÉPARATION DE CHAMP D'ONDE À L'AIDE D'UN CAPTEUR DE GRADIENT
Abstract: front page image
(EN)Seismic data relating to a subterranean structure is received from at least one translational survey sensor, and gradient sensor data is received from at least one gradient sensor. A P wavefield and an S wavefield in the seismic data are separated, based on combining the seismic data and the gradient sensor data.
(FR)Selon la présente invention, des données sismiques associées à une structure souterraine sont reçues depuis au moins un capteur de sondage de translation, et des données de capteur de gradient sont reçues depuis au moins un capteur de gradient. Un champ d'onde P et un champ d'onde S dans les données sismiques sont séparés, sur la base d'une combinaison des données sismiques et des données de capteur de gradient.
