Title (EN) ANOMALY DETECTION SYSTEMS AND METHODS EMPLOYING A DOWNHOLE TOOL WITH AXIALLY-SPACED SENSOR PACKAGES
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTECTION D'ANOMALIE UTILISANT UN OUTIL DE FOND DE TROU AVEC DES ENSEMBLES CAPTEUR ESPACÉS AXIALEMENT
Abstract:
(EN) A system includes a downhole tool deployed in a borehole, the downhole tool having a plurality of axially-spaced sensor packages. The system also includes a processor configured to analyze measurements collected at different times and by different ones of the plurality of axially-spaced sensor packages at a position of interest along the borehole. The processor detects an anomaly based on the collected measurements.
(FR) L'invention concerne un système comprenant un outil de fond de trou déployé dans un trou de forage, l'outil de fond de trou étant doté d'une pluralité d'ensembles capteur espacés axialement. Le système comprend également un processeur configuré pour analyser des mesures collectées à différents moments et par des ensembles capteur différents de la pluralité d'ensembles capteur espacés axialement au niveau d'une position d'intérêt le long du trou de forage. Le processeur détecte une anomalie sur la base des mesures collectées.
