Abstract
Field testing of electrochemical noise monitoring has been conducted at the Simonette sour oil processing facility since August of 1997. Results from the installation at the Simonette sour oil processing facility are promising and have provided valuable insight into which process variables significantly affect corrosion rates and mechanisms in the system. Because electrochemical noise measurements allow monitoring of corrosion activity in real time, it has been possible to correlate specific changes in process conditions with corrosion events.
Data from the electrochemical noise probe installed at the Simonette facility has been correlated to process changes as well as used to evaluate the chemical program in the stabilizer system, including measurement of the inhibitor film persistency. The electrochemical noise data was also used to define the effect of producing acid treatment fluids from wells into the battery on corrosion in the stabilizer system.
