The present invention provides a system that monitors and controls the precipitation of asphaltenes in a formation fluid by using a sensor (35) to make a direct real-time on-site measurement of the relative concentration asphaltenes from at least one location at a wellsite or in a pipeline. Using a processor (145) to compare sequential measurements, the system of the present invention can trigger the addition of additives in response to a change in asphaltene concentration in the formation fluid, preventing precipitation.
La présente invention concerne un système qui surveille et commande au moyen d'un capteur (35) la précipitation d'asphaltènes dans un fluide de formation pour effectuer une mesure directe, sur le terrain et en temps réel de la concentration relative en asphaltènes à partir d'au moins un point de l'emplacement de forage ou du pipeline. A l'aide d'un processeur (145) servant à comparer des mesures séquentielles, le système selon la présente invention peut déclencher l'addition d'adjuvants en réaction à un changement de la concentration en asphaltènes du fluide de formation, empêchant la précipitation.
