Title (EN) COMPENSATING SEISMIC DATA FOR SOURCE VARIATIONS
(FR) COMPENSATION DES VARIATIONS DE LA SOURCE DANS DES DONNÉES SISMIQUES
Abstract:
(EN) A technique includes modeling a fundamental component of a vibroseis sweep that is injected into the earth based on a ground force measurement and a reference sweep. The technique includes determining an operator to compensate seismic data acquired in response to the injected vibroseis sweep based at least in part on the reference sweep and the fundamental component, and the technique includes applying the operator to the seismic data.
(FR) On décrit une technique comprenant la modélisation d'une composante fondamentale d'un balayage vibrosismique injecté dans la terre sur la base d'une mesure de force au sol et d'un balayage de référence. La technique comporte une étape consistant à déterminer un opérateur destiné à corriger des données sismiques acquises en réponse au balayage vibrosismique injecté, en se basant au moins en partie sur le balayage de référence et sur la composante fondamentale, la technique comprenant également une étape consistant à appliquer l'opérateur aux données sismiques.
