Claim Text:
1. A method of inhibiting the corrosion in a fluid conducting and containment system used to screen, test, produce and process oil and gas, and their products, the method comprising the steps of: a) selecting a fluid conducting and containment system, used to screen, test, produce and process oil and gas, and their products, to be treated; b) adding a corrosion inhibitor comprising at least one amphiphilic chemical to the fluid in the system; c) (i) sampling the fluid at-line, online or off-line and adding a marker solution containing a marker which can emit an optically detectable signal to the sample; or d) measuring micelles in the fluid by detecting the optically detectable signal emitted from the fluid; and e) optimizing the further addition of corrosion inhibitor once micelles are detected in the fluid, in order to maintain an effective concentration to maximize protection and minimize the overuse of the inhibitor, by continuing to monitor for the presence of micelles in the fluid.
