Title (EN) METHODS AND APPARATUS FOR DETERMINING DOWNHOLE PARAMETERS
(FR) PROCÉDÉS ET APPAREILS POUR DÉTERMINER DES PARAMÈTRES DE FOND
Abstract:
(EN) Apparatus and methods for determining downhole fluid parameters are disclosed herein. An example method includes deploying a downhole apparatus into a wellbore. The downhole apparatus includes a sensor having a heater and a temperature sensor. The method also includes traversing the downhole apparatus through the wellbore and obtaining a first response with the sensor in a first position of the wellbore. The method also includes obtaining a second response with the sensor in a second position of wellbore and determining a presence of a boundary between the first and second positions based on the first and second responses.
(FR) L'invention concerne des procédés et des appareils pour déterminer des paramètres de fluide de fond. Un procédé donné à titre d'exemple consiste à déployer un appareil de fond dans un trou de forage. Cet appareil de fond comprend un capteur présentant un élément chauffant et un capteur de température. Ce procédé consiste également à faire passer l'appareil de fond à travers le trou de forage et à obtenir une première réponse au moyen du capteur à un premier emplacement du trou de forage. Ce procédé consiste en outre à obtenir une deuxième réponse au moyen du capteur à un deuxième emplacement du trou de forage et à déterminer la présence d'une limite entre le premier et le deuxième emplacement, sur la base de la première et de la deuxième réponse.
