Title (EN) DETECTION OF LOCATION OF CEMENT
(FR) DÉTECTION DE LA LOCALISATION DE CIMENT
Abstract:
(EN) Included are cement compositions and methods and systems for locating the cement compositions in a wellbore. An example method comprises deploying a sensing system in the wellbore and introducing the cement composition into the wellbore. The cement composition comprises a cement and hollow beads having a crush pressure and configured to emit an acoustic signal when imploded. The method further comprises pumping the cement composition through the wellbore to a depth with a wellbore pressure exceeding the crush pressure of the hollow beads to induce implosion of the hollow beads and the emission of the acoustic signal. The method further comprises sensing the emitted acoustic signal and determining the location of the cement composition in the wellbore from the sensed emitted acoustic signal.
(FR) L'invention concerne des compositions de ciment et des procédés et des systèmes pour la localisation des compositions de ciment dans un puits de forage. Un exemple de procédé comprend le déploiement d'un système de détection dans le puits de forage et l'introduction de la composition de ciment dans le puits de forage. La composition de ciment comprend un ciment et des billes creuses présentant une certaine pression d'écrasement et conçues pour émettre un signal acoustique lors de leur implosion. Le procédé comprend en outre le pompage de la composition de ciment à travers le puits de forage jusqu'à une profondeur au niveau de laquelle la pression du puits de forage dépasse la pression d'écrasement des billes creuses pour induire l'implosion des billes creuses et l'émission du signal acoustique. Le procédé comprend en outre la détection du signal acoustique émis et la détermination de la localisation de la composition de ciment dans le puits de forage à partir du signal acoustique émis ainsi détecté.
