Title (EN) WELLBORES UTILIZING FIBER OPTIC-BASED SENSORS AND OPERATING DEVICES
(FR) PUITS UTILISANT DES DETECTEURS ET DES EQUIPEMENTS OPERATIONNELS A BASE DE FIBRES OPTIQUES
Abstract:
(EN) This invention provides a method for controlling production operations using fiber optic devices. An optical fiber carrying fiber-optic sensor is deployed downhole to provide information about downhole conditions. Parameters related to the chemicals being used for surface treatments are measured in real time and on-line, and these measured parameters are used to control the dosage of chemicals into the surface treatment system. The information is also used to control downhole devices that may be a packer, choke, sliding sleeve, perforating device, flow control valve, completion device, an anchor or any other device. Provision is also made for control of secondary recovery operations on-line using the downhole sensors to monitor the reservoir conditions. The present invention also provides a method of generating motive power in a wellbore utilizing optical energy. This can be done directly or indirectly, e.g., by first producing electrical energy that is then converted to another form of energy.
(FR) L'invention porte sur un procédé de commande des opérations de production à l'aide de dispositifs à fibres optiques. Un détecteur muni de fibres optiques est descendu en fond de puits pour fournir des informations sur les conditions y régnant. On peut ainsi mesurer en temps réel et en ligne différents paramètres relatifs aux produits chimiques utilisés pour traiter les surfaces, et utiliser lesdits paramètres pour régler le dosage de ces produits dans le système de traitement des surfaces. On peut également utiliser des informations pour commander les dispositifs de fond de puits tels que les packers, les duses, les manchons coulissants, les dispositifs de perforation, les vannes de commande de débit, les outils de mise en production, les ancres, etc. Il est également possible de commander certaines opérations en ligne de récupération secondaire à l'aide desdits détecteurs qui suivent l'état des roches réservoirs. L'invention porte également sur un procédé de production dans un puits d'énergie motrice par utilisation d'énergie optique, soit directement, soit indirectement, par exemple en produisant d'abord de l'énergie électrique qui est ensuite convertie en une autre forme d'énergie.
