Abstract

L'échantillonnage spatial est un facteur clé pour déterminer des paramètres d'acquisition pour des relevés sismiques. L'acquisition de données pour répondre aux exigences de l'échantillonnage spatial pour les basses, moyennes et hautes fréquences, par l'acquisition de grilles d'acquisition grossières, moyennes et fines respectivement, et la superposition de ces grilles au cours du traitement, permettent d'obtenir des relevés de coûts réduits et/ou de qualité supérieure.
