Preventing the internal corrosion of crude oil, natural gas, and water injection pipelines involves numerous steps, which operators should follow to ensure the integrity of oil and gas field pipelines that are essential for uninterrupted production.
A study was recently conducted to determine the viability of vapor corrosion inhibitor (VCI) technology in mitigating corrosion. Overall, VCIs were found to be effective in mitigating corrosion when recommended dosages are used, and they could also be used in combination with impressed current CP systems.
The usual challenge for stainless steel pickling involves removing all scale, iron contamination, and welding oxides to achieve a fully passivated surface with an even, clean, and aesthetic finish. In this case, a new nitric-acid-free process was installed at a large beer barrel plant in Spain.
Ammonium chloride corrosion is an aggressive form of localized, underdeposit corrosion commonly found in overhead equipment and piping associated with crude units.
When steels corrode under a high-pressure, high-temperature multiphase environment containing supercritical carbon dioxide, various gas impurities, salts, crude oil, and solid particles merit further investigation.
Molecular microbiological methods (MMM) are becoming more commonly used as an alternative for culture-based methods for estimating bacterial numbers in oilfield systems.
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.
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.
University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.
A reaction between high-pH monoethanolamine and carbon dioxide formed a carbonate/bicarbonate solution that led to intergranular stress corrosion cracking.
A better appreciation of the various components of typical corrosion costs in the oil and gas industry could further facilitate their optimization.
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.
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.
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.
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.
