(EN) Method and apparatus for controlling chemical injection of a surface treatment system
(FR) Procédé et appareil pour le contrôle d'injection chimique d'un système de traitement en surface
Abstract: front page image
(EN) An apparatus for controlling chemical injection of a surface treatment system for an oilfield well, said apparatus comprising: a chemical injecting device injecting one or more chemicals into the treatment system for the treatment of fluids produced from an oilfield well; at least one chemical sensor associated with the treatment system for sensing at least one parameter of the injected chemical or for sensing at least one chemical property of the fluids produced from the oilfield well; and a control and monitoring system for controlling the chemical injection device in response, at least in part, to information from said downhole chemical sensor.
