Determination Of Oxygen Limits For Corrosion Resistant Alloys (Cras) In Oil & Gas Produced Water Based On Electrochemical Test Methods – Part 1

Product Number: 51322-17939-SG

Corrosion Resistant Alloys (CRAs) have been widely used in oil & gas process systems since the 1980s due to their excellent resistance towards uniform corrosion in aggressive environments such as seawater and produced water containing CO₂, organic acids and/or production chemicals. However, cases of localized corrosion in the form of pitting and crevice corrosion have regularly been observed. As an example, ISO⁽²⁾ 21457 limits the max. operating temperature to 20⁰C for 25 Cr super duplex stainless steel (UNS S32750/760) and 6-Mo austenittic stainless steels (UNS S31254) in chlorinated seawater systems, to avoid crevice corrosion.¹

Crevice corrosion is a geometrical-dependent type of localized attack that occurs in occluded regions where a stagnant and corrosive electrolyte is in contact with the surface of a passive metal^1,2. Crevices are present in all industrial designs and can lead to major failure since their detection is often challenging^3,4. Main strategies for the prevention and mitigation of crevice corrosion include design awareness and adequate materials selection⁵.

Determining Distribution Rate Of Vapor Corrosion Inhibitors Using Corrosion Potential Data

Product Number: 51322-17970-SG

High-level radioactive waste generated during reprocessing of spent nuclear fuel at Hanford has been stored in several single- and 27 double shell tanks (DSTs). Each DST consists of a primary shell (inner) surrounded by secondary (outer) liner. The secondary liner rests on a concrete foundation. Rainwater may seep in and accumulate in the drain slots and may corrode the exterior of the secondary liner. Evidence of wall thinning has been detected via ultrasonic inspections of the annulus floor between the primary and secondary tank shells. Since the inspection is confined to this region, there is a concern that corrosion is widespread on the underside of the bottom plate.

Development And Application Of A Thermochemical Database (MSTDB-TC) To Modeling Corrosion In Molten Salt Reactors

Product Number: ED22-17137-SG

Accurate representations of the thermochemistry and phase equilibria of relevant molten salt constituents and their aggregate behavior are critical to the development, design, operation, and licensing of any molten salt reactor (MSR). This need is currently being addressed by the creation of a dedicated, high quality/validated MSR thermochemical database, the Molten Salt Thermal Properties Database-Thermochemical (MSTDB-TC). MSTDB-TC is being populated with prioritized models and values for vapor species, and liquid and crystalline phases of chloride and fluoride fuel and coolant salts with relevant fission product and transuranic elements, and more recently with corrosion-relevant systems with chromium, iron, and nickel. Multi-cation crystalline and melt solution models are being incorporated, including newly developed relations as necessary, to obtain real system behavior.

Development Of A F22 Compatible Scale Inhibitor

Product Number: 51322-17610-SG

Author: Ya Liu, Benton Hutchinson, Rose Lehman, Jeffrey Russek, James Outlaw

Publication Date: 2022

$20.00

F22 is a low alloy steel that typically contains 12% Carbon, 2.25% Chromium, and 1.0% Molybdenum1. This steel has been widely used in oil production systems, especially in well head design and construction. As a low alloy steel, F22 can be corroded by oilfield chemicals under certain circumstances. For example, it was observed in the Gulf of Mexico that typical scale inhibitor chemistries caused severe corrosion on F22.

Development Of An Efficient MIC Mitigation And Control Strategy In Pipelline Pigging Operations

Product Number: 51322-17632-SG

Publication Date: 2022

An operating company was concerned that its biocide and corrosion mitigation strategy was not sufficient to control corrosion in their pigging operations across the Gulf Coast of Texas. They provided water samples from several pigging access points that were heavily contaminated with SRBs, APBs, black deposits and oil. H₂S was present in most of the samples suggesting a heavy presence of SRBs. They suspected that the black deposits were most likely FeS caused by the presence of microorganisms interacting with their pipelines. Indeed, culture vial tests (sometimes referred to as “bug bottles”) proved that the samples were heavily contaminated with microorganisms.

Development Of Deficient Grout And Corrosion In Post-Tensioned Tendons Due To Water And Solute Transport

Product Number: 51322-17986-SG

Publication Date: 2022

Bridge construction utilizing post-tensioned (PT) tendon systems have become increasingly popular. ^1-2 PT construction allows engineers greater options for the design of highway bridges and provides efficient structures with advantages in construction, economy, and serviceability. In bonded post stresses to the reinfotensioned systems, the introduction of rced concrete element is made through tensioned highstrength steel strand that are anchored and encapsulated in a cementitious grout within a tendon.^3-4 The hardened grout allows development of the stress along the length of the tendon and also provides corrosion protection by the presence of the alkaline pore water to passivate the steel strand and by creating a barrier from external contaminants.

Mineral scales frequently occur in tanks, pipelines, cooling and heating system, production wells of
oil and gas, external and internal membrane, and other equipment during industrial processes,
causing the reduction of process efficacy and millions of dollars on dealing with the scale issues. As
oil and gas are produced increasingly in more unconventional reservoirs, such as deeper and tighter
zones, with new technologies, more challenges are encountered to mitigate scale problems.

Development Of For Multifunctional (Pit Detection + ER) Corrosion Monitoring Probe For Oil And Gas Internal Pipelines

Product Number: 51322-17820-SG

Publication Date: 2022

$20.00

One of the frequent and major problems encountered in the oil and gas production is the
internal corrosion of carbon steel pipelines. Corrosion can be categorized into uniform (or
general) corrosion, localized corrosion and erosion-corrosion. Uniform corrosion causes
overall metal loss and general thinning of metal. Localized corrosion has the appearance
of pits or grooves.

Several components in geothermal power plants need to be protected from the environment due to the corrosive nature of geothermal fluids used to generate the energy. Depending on the fluid properties for any location, the type of protection varies. In geothermal power plants, wear, erosion, corrosion, and scaling are all known problems1. These issues can lead to a variety of outcomes, ranging from decreased plant efficiency to upstream component failure. Failure of a component is thus a significant challenge in the geothermal industry, where materials need to operate in high temperature and high pressure environments. A major cost factor is also linked to the drilling of geothermal wells, where cost rises due to increased depth/distance of drilling, increased trip times, higher high temperature and high-pressure conditions which can lead to increased wear and corrosion of the materials. To address the issue, coatings can be considered to be a potential solution to extend the service life of downhole equipment.

Oilfield sulfide scale formation is peculiar to sour production scenarios, and for many oil and gas fields the issue of iron sulfide scale management downhole presents a major challenge. Historically iron sulfide scaling downwell have featured ‘reactive’ chemical dissolver interventions to recover well production once sulfide scale has deposited, and operators have published extensively on their experiences i.e. coiled tubing deployed dissolver technologies used in well clean-out treatments (Green, et.al. 2014, Wang et.al. 2017, Wang et.al. 2018, Buali et. al 2014).

Application of corrosion inhibitors confer many advantages for combatting internal pipeline corrosion in the upstream oil and gas industry. It is known that the associated costs for using corrosion inhibitors are low compared to other mitigation techniques [1]. For continuous injection procedures, water-soluble inhibitors are not expected to form long-lasting films, so they must be continuously injected to maintain their effectiveness. Batch inhibitors are usually higher molecular weight species and oil soluble. They tend to be more tenacious, providing a protective barrier between the water and the metal over a long period of time.
