Experimentation to Develop a Quantitative Method for Characterizing the Level of Flash Rusting Formed on Carbon Steel after Ultra High Pressure Waterjetting

Product Number: 41206-253-SG
Author: Moavin Islam, Wayne McGaulley, James Tagert
Publication Date: 2006
$20.00

High pressure (HP) and ultra-high pressure (UHP) waterjetting for coating removal and surface preparation has several advantages compared to the industry standard abrasive grit blasting process.  However, a major drawback of waterjetting is subsequent flash rusting of the steel surface. The color of the flash rust is typically orange, red, or brown of various shades depending on the color of the underlying steel, the nature of the surrounding environment, and the duration of exposure to the environment.

Cathodic Protection (CP) System at Gas Wells Maintenance and Troubleshooting

Product Number: MPWT19-14286
Author: Mohammed M Alsaaq
Publication Date: 2019
$0.00

A cathodic protection (CP) system reduces corrosion by minimizing the difference in potential between the anode and the cathode. This reduction can be achieved by applying a current to the structure to be protected from an electrical source. When enough current is applied, the whole structure will be at one potential, thus anode and cathode sites will not exist. CP is commonly used on many types of structures, such as pipelines and underground storage tanks.
The paper is about an effort to improve Southern Area Gas Producing Facilities’ (SAGPF’s) CP system in compliance with all related Saudi Aramco standards, procedures, and GIs, and provides in depth analysis and recommendations to mitigate CP system challenges, and to make CP system reliable. In addition, the study aims to identify key tasks to minimize the effect of component failures and to increase the reliability of SAGPF remote monitoring units, to get accurate data. The onsite CP system survey was performed from April 26 to September 30, 2018, for all SAGPF. This paper is focused on the major challenges, such as equipment failures, operational deficiencies, and technical recommendations to make the CP system efficient and reliable.

Materials Performance and Challenges in Oil and Gas Production Wells

Product Number: 51319-13294-SG

Integrity of materials in Oil & Gas production wells is critical to meet the objectives of design and the lifecycle performance of wells. This is significant value both in economic terms and health safety and environment. Subsurface uncertainties Aging fields EOR activities and also the quality of procured equipment add to the difficulties in preventing equipment failures in wells. Failures that are especially unforeseen or unanticipated provide crucial feedback to operators and lessons to be learnt. It is imperative for operators to learn improve processes and avoid recurrence of failures.Petroleum Development Oman (PDO) as a large operator with more than 10000 wells has gained important experience and lessons from many such failures. This has contributed significantly to improve the company standards material selection reset the operating envelope and procedures enhance surveillance and improve upon quality assurance and control of new equipment.This paper is a compilation of some of the important lessons learnt from such incidents in the recent past. It discusses the operational experience and learning from different subsurface materials from CS to nickel alloys used in different components such as casing tubing packers and X-trees.

Low Temperature Effect on Sulfide Stress Crack Initiation in Low Alloy Steels

Product Number: 51319-12856-SG
Author: Brian Chambers
Publication Date: 2019
$20.00

Exposure temperature has a known effect on sulfide stress cracking (SSC) where elevated temperatures permit the use of oil country tubular goods (OCTG) in sour conditions that would not be survivable at lower temperatures. In order to assess SSC susceptibility NACE MR0175 / ISO15156-2 and API 5CT advise or require the use of room temperature NACE exposure tests in H2S-containing brines and consequently the bulk of qualification data on OCTG has been obtained at these conditions. Previous publications have demonstrated the effect of lower temperatures e.g. 40°F testing on KISSC values of low alloy steel using double cantilever beam (DCB) tests showing a reduction on sour toughness when the temperature is lowered from 75°F to 40°F. This KISSC data provides a clear indication of SSC severity at 40°F on crack propagation; however very little data is available pertinent to crack initiation at temperatures lower than 75°F.In this work several crack initiation tests were performed in mild sour conditions and demonstrated that at low temperature crack initiation susceptibility is increased. Details of the results are discussed within the context of traditional SSC qualification tests and materials selection standards along with the theoretical understanding of SSC fundamentals. Cracking tendency and time-to-failure are reviewed within the context of environmental and material parameters that are altered by the exposure temperature including hydrogen diffusion corrosion rate dissolved H2S concentration and the behavior of hydrogen traps.

Understanding Alkalinity for Use in Corrosion Prediction

Product Number: 51324-21064-SG

Publication Date: 2024
$40.00
Parameters reported in production fluid water chemistry analyses are used by engineers for determination of scaling tendency and corrosivity, thus promoting optimal production rates while maintaining asset integrity. Water chemistry analysis documents report ion concentrations, total alkalinity, and various graphical data sets related to the tested brine which are designed to assist field engineers. The alkalinity value provided in these documents is of utmost importance to corrosion engineers as it is a measure of the capacity of an aqueous solution to resist changes in acidification. Alkalinity can also be directly linked to the in situ pH of the produced brine and can therefore provide key inputs to assess and predict its corrosivity. Yet, including alkalinity into corrosion production models can be challenging considering there is still much uncertainty among operators about the validity and meaning of the reported alkalinity value. For that reason, recent publications (two AMPP standards) have focused on providing additional guidelines to those who need this knowledge. This is of key importance for the optimization of appropriate and economic corrosion and scaling mitigation strategies. This paper will review the use of the alkalinity term and water chemistry analysis with goals of minimizing confusion and optimizing the use of proper data input for corrosion prediction models.

California Water Service (Cal Water) has had a team dedicated to the maintenance of its water tank infrastructure since the 1970s. The Team faces significant challenges as it strives to maintain the reliability of more than 450 water tanks throughout the State of California. Some of these challenges include tighter State regulations, increased visibility from the public, limited resources, aging infrastructure, and an aging workforce that will take their valuable institutional knowledge into retirement with them.
