Title (EN) SEISMIC IMAGING
(FR) IMAGERIE SISMIQUE
Abstract: front page image
(EN)Systems for the acquisition of seismic data. In one embodiment, a daughter vessel (11) tows a wide source (13) and an array (14) of short receiver streamers (22), while a mother vessel (12) tows a second array (15) of long receiver streamers (26). An initial survey is carried out, and multiples in the response data are filtered out. Then a second acquisition regime is carried out and the results combined with the initial survey to eliminate shadows.
(FR)La présente invention concerne des systèmes d'acquisition de données sismiques. Dans un premier mode de réalisation, un navire fils (11) tracte une source large (13) et un réseau (14) de flûtes réceptrices courtes (22), pendant qu'un navire père (12) tracte un deuxième réseau (15) de flûtes réceptrices longues (26). On procède à un premier sondage et on élimine par filtrage les multiples qui se trouvent dans les données de réponse. On effectue ensuite un second régime d'acquisition et on combine les résultats avec ceux du premier sondage pour éliminer les ombres.
