The present invention provides an apparatus and methods for detecting the behavior of perforations in a wellbore casing, the apparatus including a sensor array movable within the internal diameter of the casing, the sensor array having one or more sensors located proximate the internal surface of the casing with the sensors being located or oriented such that properties of flow from a proximate perforation can be distinguished from properties of a main flow through the wellbore.
La présente invention concerne un appareil et des procédés pour détecter le fonctionnement de perforations dans un cuvelage de puits de forage, l'appareil comprenant un ensemble de capteurs (10) mobile dans le diamètre interne du cuvelage, l'ensemble de capteurs ayant un ou plusieurs capteurs (16) situés à proximité de la surface interne du cuvelage avec les capteurs étant situés ou orientés de telle sorte que les propriétés d'un flux provenant d'une perforation voisine peuvent être distinguées des propriétés d'un flux principal à travers le puits de forage.
