Title (EN) LOW-FREQUENCY DAS SNR IMPROVEMENT
(FR) AMÉLIORATION DU RSB D'UNE DÉTECTION ACOUSTIQUE RÉPARTIE À BASSE FRÉQUENCE
Abstract:
(EN) A workflow for optimizing production of a hydrocarbon reservoir and optimizing a hydraulic fracturing model of a hydrocarbon reservoir using techniques for improving signal-to-noise ratio and decreasing interferences for Low-Frequency Distributed Acoustic Sensing is described. Acoustic sensor data is collected from optical fiber, where said data is processed to optimize production parameters and well production.
(FR) La présente invention concerne un flux de travail pour optimiser la production d'un réservoir d'hydrocarbure et optimiser un modèle de fracturation hydraulique d'un réservoir d'hydrocarbure au moyen de techniques permettant d'améliorer le rapport signal sur bruit et de diminuer les interférences pour une détection acoustique répartie. Des données de capteur acoustique sont collectées à partir d'une fibre optique, lesdites données étant traitées pour optimiser les paramètres de production et la production du puits.
