Nanotechnology-Based Field Method for Detection and Monitoring of Corrosion Inhibitors

Accurate and precise monitoring of corrosion inhibitors in oilfield brine, an important aspect of corrosion control in oil and gas operations, is also a practice recommended by NACE International guidelines. Many operators require residual concentrations of corrosion inhibitors to monitor chemical deliverability at specific locations in a production system.  The residual measurement provides the ability to troubleshoot factors affecting chemical deliverability.  However, residual measurements are notoriously problematic because of the surface-active nature of corrosion inhibitors.  Residual measurement errors can often exceed 100 percent.  Consequently, a need exists for methods that are precise and accurately detect a wider range of corrosion inhibitor molecules.  These methods must also be viable in corrosive oilfield environments where corrosion inhibitors are at low concentrations.  Furthermore, the methods must be portable, enabling field analysis of residual chemicals in collected samples.  Field-based detection methods can reduce the amount of time required to obtain data useful for corrosion control and reduce delays associated in shipping samples to centralized laboratories.
