Title (EN) METHODS AND SYSTEMS EMPLOYING A FLOW PREDICTION MODEL THAT IS A FUNCTION OF PERFORATION CLUSTER GEOMETRY, FLUID CHARACTERISTICS, AND ACOUSTIC ACTIVITY
(FR) PROCÉDÉS ET SYSTÈMES UTILISANT UN MODÈLE DE PRÉDICTION DE DÉBIT QUI EST FONCTION DE LA GÉOMÉTRIE EN GRAPPES DES PERFORATIONS, DES CARACTÉRISTIQUES DE FLUIDE, ET DE L'ACTIVITÉ ACOUSTIQUE
Abstract:
(EN) A method includes obtaining distributed measurements of acoustic energy as a function of time and position downhole. The method also includes deriving acoustic activity values as a function of time and position from the one or more distributed measurements. The method also includes predicting fluid flow for a downhole perforation cluster as a function of time, wherein predicting fluid flow involves a flow prediction model that is a function of perforation cluster geometry, fluid characteristics, and at least one of the acoustic activity values. The method also includes storing or displaying the predicted fluid flow.
(FR) L'invention concerne un procédé comprenant l'étape consistant à obtenir des mesures distribuées de l'énergie acoustique en fonction du temps et de la position en fond de trou. Le procédé comprend également l'étape consistant à dériver des valeurs d'activité acoustique en fonction du temps et de la position à partir desdites une ou plusieurs mesures distribuées. Le procédé comprend également l'étape consistant à prédire le débit d'un fluide pour une grappe de perforations de fond de trou en fonction du temps, dans lequel la prédiction du débit du fluide comprend un modèle de prédiction de débit qui est fonction de la géométrie en grappes de perforations, des caractéristiques de fluide, et d'au moins l'une des valeurs d'activité acoustique. Le procédé comprend également l'étape consistant à stocker ou afficher le débit de fluide prédit.
