Abstract
An electrode assembly (probe) has been developed that allows the use of linear polarization methods to study corrosion in high solution resistance environments, with no additional equipment or electrical shielding required, except that commonly used for low solution resistance environments. In a crude oil/water environment, this corrosion probe functions equally well if either crude oil or water is the continuous phase. Corrosion rates determined by standard linear polarization measurements, using the probe quantitatively, agree with coupon weight loss measurements made simultaneously under identical experimental conditions. Field trials in a crude oil flowline have demonstrated that the electrochemical probe retains its characteristics over an extended period of time in service.
