Corrosion-related losses represent approximately 30% of the hydrocarbons extraction and treatment industry's failures, with a total annual cost of US$ 1.372 billion. The oil&gas industry has widely recognized the importance of implementing effective prediction and management systems to reduce costs and guarantee compliance with safety, health, and environmental regulations. In this context, it is safe to narrow the oilfield corrosion problem mainly towards the two most severe degradation cases observed during operation: the sweet CO₂-related and H₂S-related corrosion.

Tailoring Scale Prediction Models to a Specific Application: Reverse Osmosis

Product Number: 51319-13238-SG

Mineral scale formation is a problem across many industries and in diverse applications and equipment. Each application may have specific characteristics that must be taken into account if a modelling system is to be reasonably accurate. The modelling of cooling water and oil field production chemistry have been studied extensively since the 1970’s and state-of-the-art physical chemistry models devloped to simulate them with acceptable accuracy even under extreme conditions.Open recirculating cooling water predictive models for example must incorporate algorithms to concentrate the water treating the process as an “open” system and address cooling stem specific situations including pH control methods and even the impact of chlorination. pH prediction of the concentrated recirculating water is a key requirement.Oil and gas production chemistry modelling presents another set of unique challenges including the distribution of gasses such carbon dioxide and hydrogen sulfide between phases as a brine transitions from bottom hole conditions to the well head and then flashes at the separator. Such a system must incorporate algorithms to treat the process as a “closed” system and partition the critical gasses between phases with pressure and temperature changes and account for the impact of the sometimes dramatic environmental parameter changes upon pH solubility and physical constants.Membrane systems did not begin to receive the same rigorous treatment as oil and gas production cooling water and applications such as geothermal power production until the 1990’s. Much of the software in use by the industry relies upon simple index calculations on the level of the Langelier Saturation Index and saturation indices based upon total analytical values. The mainstream reverse osmosis application specific software generally used is not up to the rigors of high ionic strength high recovery and water reuse membrane systems. They are definitely not capable of adequately modelling cascade systems. The simple indices used for predicting scale formation and as driving forces for dosage optimization do not simulate high ionic strength activity coefficients and near as well as far effects. The simple models fail to account for speciation and the ion association of even such standard (yet critical) pairs such as CaSO4o aqueous.Scale inhibitor models in these simple models also do not account for inhibitor dissociation and the active form of the molecules. They also tend to lack the sophistication of models used in other applications which necessitate an induction time extension approach. Without adequate speciation models inhibitor solubility can not be adequately taken into account or insoluble forms controlled predictably.They also ignore in many cases application specific challenges such as membrane specific ion rejection pH prediction and control in vented (open) or tight (closed) systems and concentration polarization at the membrane water interfaceThis paper discusses the practical application of advanced physical chemistry techniques commonly employed in cooling water and oil field chemistry to application specific modelling of mineral scale formation and control in membrane systems.The techniques are discussed and applied to:· Predicting scale formation;· Identifying the upper driving force limit for inhibitors and blends;· Developing inhibitor models for minimum effective dosage; and· Developing models for preventing failure due to inhibitor solubility.The methods discussed have been validated in field applications.

Tank Waste And Ground Water Effects On The Corrosion Susceptibility Of The Secondary Liner Of Hanford Double-Shell Tanks

Product Number: 51322-17550-SG

Author: Sheewa Xihuahe Feng, Jason S. Page

Publication Date: 2022

$20.00

The nuclear waste at the Hanford Site is currently stored in 131 single-shell tanks and 27 double-shell tanks (DSTs). When the primary liner in Tank 241-AY-102 (AY-102) failed, the secondary liner became the principal barrier of the tank, and leaked waste interacted with the refractory foundation beneath the primary liner. The high caustic concentration of the tank waste could have reacted with the tank refractory, lowering the pH and leading to increased corrosion rates of the annulus tank steel. The extent of change would depend on the waste volume to surface area ratio and other factors.

The effects of corrosion are wide-spread and widely known. From construction to transportation and everything in between corrosion is a result of environmental effects on the metals we use to build. Corrosion may be controlled, however, through the use of inhibitors as an on-going treatment in order to effectively stall the act of corrosion.

Technical Review on the Existence of Type B (Alumina) Inclusion at Hot Steel Making Process

Product Number: MPWT19-15601

Publication Date: 2019

It is well known in the hot rolled steel making business that nonmetallic inclusions play critical
role in defining steel performance. The objective of this paper is to study laminations that were
detected via Phased Array UT system in X60MS Class-C High Frequency Welded Pipe intended for
offshore application. The linear intermittent laminations appear along the pipe and adjacent to
the weld seam from both sides at a width of 30 to 40 mm with various depths. Technical review
was carried out on 5 available pipes, pertaining to the same heat of the original pipe identified
earlier with lamination, through model experiments; both on the laboratory and on the industrial
scale. At the beginning, depth and distribution of detected laminations were analyzed by manual
UT mapping using normal beam probe. Metallurgical analysis via Energy Dispersive X-ray (EDX)
was carried out on three samples to determine the chemical composition as well as the
morphology of the lamination. The type of inclusion which turned out to be type B (Alumina-
Al2O3) inclusion was identified by evaluating EDX results using Method A per ASTM E45. As it is
a pure material based incident, failure analysis was carried out by the steel maker to identify the
associated root causes from process control prospective and the appropriate preventive
measures to avoid reoccurrence. Eventually, the applied quality control measures during
manufacturing process of HFW pipes, represented in the deployment of UT systems, were
reviewed to identify the reason behind missing such important defect before pipes are being
shipped to the client.

Composite repairs have been applied to pipelines and piping systems for structural reinforcement after external corrosion. Such repairs may consist of glass or carbon fibers embedded in a matrix of epoxy. Typically, these repairs are hand applied using either wet lay-up systems or prefabricated rolls of composite sleeve. In some applications, pipeline continued corrosion growth under composite repairs were reported using Inline Inspection (ILI) which raises a concern about the integrity of the metallic piping under composite repairs. When continued corrosion is detected by ILI, a difficulty is typically faced due to the inability to measure pipeline remaining thickness under such repairs. To resolve this challenge, this paper will discuss multiple inspection and corrosion monitoring techniques for metal loss under composite repairs. To measure the pipeline wall thickness due to internal corrosion, one or more of the three (3) Non-Destructive Testing (NDT) technologies namely; Dynamic Response Spectroscopy (DRS), Multi-skip Ultrasonic (MS-UT) and digital radiography were evaluated and found capable. To monitor for external corrosion, a scheduled visual inspection of the composite repair would be the first inspection step. If the composite repair appears to be intact then the visual inspection would suffice and the repair should be acceptable to its design life. If the original defect is external corrosion and a scheduled visual inspection of the composite repair shows damage to the composite repair then inspection to assess the integrity of the substrate must be used before permanently fixing the composite repair. For this scenario, digital radiography or MS-UT are recommended to assess the condition of the substrate
