In Upstream, CRAs (Corrosion Resistant Alloys) are widely selected to handle seawater and brines in piping, valves, pumps, heat exchangers, vessels, and seawater injection^1-4. Also, disposal of produced water is commonly performed through injection into spent fields. Water from a variety of sources including produced water, seawater and surface/fresh water may also be injected to create pressure drive for existing fields. Usually dissolved oxygen (DO) is not fully controlled when there are multiple sources of injection water and sometimes even possibility of injection of fully oxygenated water exists. For oxygenated seawater, the PREN (Pitting Resistance Equivalent Number = %Cr + 3.3 *(%Mo + 0.5 %W) + 16 %N) shall be >40 and limits are applied to the temperature4. Other applications involve Solid CRA or cladded production pipelines which may get flooded with seawater during installation and precommissioning.

Use of corrosion inhibitors (CI) to protect metallic equipment, especially carbon steel pipelines from corrosion has long been an established, effective, economic, and hence globally accepted technique. The oil and gas industry has been using CIs to protect the pipelines under various exposure conditions including sour and sweet services . Complete understanding of corrosion mechanisms under sour conditions and protecting pipeline steel under such conditions has always been a challenging task due to the complexity of such systems.

Corrosion failures in the oil and gas industry are dominated by localized failures in carbon steel; however, the industry has yet to develop standards for localized corrosion specifically for low alloy carbon steels (CS) such as UNS K03014 (API) 5LX65 [X65]) or UNS G10180 (C1018). The reasons for the lack of standardization are understandable as they are not trivial. The challenges are as follows: 1) CS pitting is more complex than pitting on stainless steels (SS) and can be impacted by corrosion byproducts and other forms of scales, and 2) surface finish of a test coupon or electrode has a significant impact on the three phases of pitting: initiation, propagation, and termination.

Throughout the oil and gas industry, carbon steel continues to be the material of choice for most downhole production tubulars and pipelines. Given the environment of typical oilfield operations, comprehensive integrity management programs are followed to guard against the threats of internal corrosion and material degradation of such assets. Although there are various corrosion mitigation options available, the application of corrosion inhibitor chemical products is commonplace given their relative ease of use and cost effectiveness.

Utility water and fire water which is desalinated is supplied by Ministry of Electricity & Water (MEW) and stored in utility/fire water tank (70-T-0002). The process areas and the tanks are protected by desalinated water as fire water backed up by sea water and the buildings are protected completely by desalinated water. Buildings to be protected by desalinated fire water are fire station, maintenance & operation building, warehouse, workshop, laboratory, and administration building. DF water system used in buildings are stagnant and for the fire water in tanks are used frequently.

Monitoring Localized and General Corrosion using Advanced Electrochemical Sensors

Product Number: 51320-14544-SG

Publication Date: 2020

In previous years, we have explored the use of electrochemical sensors for humidity and corrosion measurements inside of natural gas pipelines. Designed to operate in systems where a conductive aqueous phase is intermittent or unavailable, these membrane-based sensors utilize electrochemical techniques such as linear polarization resistance and electrochemical impedance spectroscopy to determine the environment’s corrosivity to the pipeline material. We now aim to explore this sensor’s performance and capabilities in more complex systems, specifically in environments that promote localized corrosion. Using the aforementioned electrochemical techniques, along with electrochemical noise and cyclic voltammetry, we probe and monitor localized corrosion and general corrosion of X65 steel in the presence of inorganic pitting agents. Experiments are conducted in both aqueous and nonaqueous environments. The additional functionality increases the quantity and quality of corrosion data from these sensors, offering to internal corrosion-monitoring programs a more complete picture of real-time corrosion within their natural gas pipelines.
