Title
(EN) REDUCING RESONANT NOISE IN SEISMIC DATA ACQUIRED USING A DISTRIBUTED ACOUSTIC SENSING SYSTEM
(FR) RÉDUCTION DU BRUIT DE RÉSONANCE DANS DES DONNÉES SISMIQUES ACQUISES AU MOYEN D'UN SYSTÈME DE DÉTECTION ACOUSTIQUE DISTRIBUÉ
Abstract
(EN)
A distributed acoustic sensor is positioned within a wellbore of a geologic formation. Seismic waves are detected using the distributed acoustic sensor, A raw seismic profile is generated based on the detected seismic waves. Resonant noise is identified and reduced in seismic data associated with the raw seismic profile.
(FR)
La présente invention concerne un capteur acoustique distribué qui est positionné dans un puits de forage d'une formation géologique. Des ondes sismiques sont détectées au moyen du capteur acoustique distribué. Un profil sismique brut est généré sur la base des ondes sismiques détectées. Le bruit résonant est identifié et réduit dans des données sismiques associées au profil sismique brut.
