The Science Behind It: A ‘Cultural’ Change in Detecting Microbiological Activity

Molecular microbiological methods (MMM) are becoming more commonly used as an alternative for culture-based methods for estimating bacterial numbers in oilfield systems.

Corrosion Prevention Using Real-Time Data in Oil Fields

In corrosion monitoring of oil and gas fields, there are many techniques that can provide data. Modern high-resolution corrosion monitors, including electrical resistance probes, are available. These instruments can be installed in key locations and connected to a control room computer.

Linking Microbiologically Influenced Corrosion to Microbiological Activity Using Molecular Microbiological Methods

While there are solutions to mitigate microbiologically influenced corrosion, a big challenge is to make the connection between corrosion damage and the activity of microorganisms.

Study: North American Waterways Becoming Saltier, More Alkaline

University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.

Internal Stress Corrosion Cracking of Shale Gas Flowlines

A reaction between high-pH monoethanolamine and carbon dioxide formed a carbonate/bicarbonate solution that led to intergranular stress corrosion cracking.

Corrosion Management and Cost Optimization

A better appreciation of the various components of typical corrosion costs in the oil and gas industry could further facilitate their optimization.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.

A Multifunctional Additive for Controlling Inorganic Foulants in Industrial Water Systems

This article presents performance data on polyamino polyether methylene phosphonic acid (PAPEMP) on various mineral scales commonly encountered in boiler, cooling, desalination, geothermal, gas, and oil systems.

Chromate Primer Alternative Uses Carbon Nanotubes Modified with Corrosion Inhibitors

Scientists have developed a non-chrome primer system by incorporating carbon nanotubes (CNTs) modified with organic corrosion inhibitors into an epoxy-based resin. The goal of the coating development effort was to identify promising CNT-containing non-chrome primer formulations that perform comparably to traditional chromated ones.

Corrosion Management and the Significance of Regular Reporting

Regular inspection, monitoring, sampling, and chemical treatment activities are needed to mitigate corrosion. Data are not always adequately reported on a regular basis, however, which could gradually render an asset integrity management system less effective.

Non-Phosphorus Cooling Tower Treatment Provides Advanced Corrosion Protection

In anticipation of the tightening restrictions on phosphorus and many of the metal-bearing compounds currently used in industrial cooling treatment, a “green” corrosion and scale inhibition technology was developed that contains no phosphorus while providing corrosion and scale control performance.

NACE International’s Annual Corrosion Career Survey Results for 2015

Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.

Wanted: Technical Articles for MP

To successfully communicate the wide variety of corrosion-related issues affecting corrosion professionals today, MP is actively encouraging corrosion control professionals worldwide to submit technical articles to share their corrosion-related experiences with over 36,000 NACE International members around the globe.

Pipeline Corrosion Issues Related to Carbon Capture, Transportation, and Storage

For the foreseeable future, fossil fuels will continue to be the dominant source of the world’s primary energy production. There has been growing concern that the use of these carbon-based fuels produces greenhouse gases, principally carbon dioxide (CO2), which adversely affect the global climate and environment. One way to mitigate the problem is to use carbon capture, transportation, and storage (CCTS) techniques and systems.

A Closer Look at Microbiologically Influenced Corrosion

Microbiologically influenced corrosion (MIC) refers to corrosion caused by the presence and activities of microorganisms—microalgae, bacteria, and fungi. While microorganisms do not produce unique types of corrosion, they can accelerate corrosion reactions or shift corrosion mechanisms. Microbial action has been identified as a contributor to rapid corrosion of metals and alloys exposed to soils; seawater, distilled water, and freshwater; crude oil, hydrocarbon fuels, and process chemicals; and sewage. Many industries and infrastructure are affected by MIC, including oil production, power generation, transportation, and water and waste water.
