Pipelines are one of the essential elements in the upstream oil and gas operation network. Transportation of the produced products to the end client is ensured through maintaining the pipeline integrity. Internal corrosion is one of the major problems that could directly affect pipeline integrity and, in severe cases, lead to failure. Different internal corrosion monitoring techniques are available to assess and evaluate fluid corrosivity and monitor it. Online Corrosion Monitoring (OCM) that uses corrosion coupons are widely utilized to measure the corrosion and pitting rate, in addition to fluid and bacteria analysis for fluid sample collected from cleaning pigging processes that qualitatively and quantitatively reflect the fluid corrosivity. Inline inspection (ILI) is a very sophisticated non-destructive inspection technique conducted for identifying pitting corrosion, erosion, cracks, and other types of pipeline defects. This paper presents a case study on correlates the Online Corrosion Monitoring (OCM) data, Wet chemistry analysis of the fluid, cleaning pigging samples, operational Data along with Inline inspection (ILI) data for one of the main and critical North Kuwait crude export pipeline. The paper's outcome could be utilized for implementing a good corrosion mitigation plan and prioritizing and following up on the action plans of the Crude pipelines.

Corrosion inhibitors provide a cost effective method for internal corrosion control of carbon and low alloy steel infrastructure within the oil and gas industry. The correct selection and validation of inhibitors is essential to ensure successful, safe and reliable operation of infrastructure. Corrosion inhibitors used in upstream oil and gas production are characteristic of surfactant molecules, which adsorb at the metalsolution interface, creating a dynamic physical barrier that reduces electrochemical dissolution.

Correlating Qualitative Surface Profile Assessment Methods To Quantitative Methodology On Prepared Concrete

Product Number: 51322-17606-SG

Publication Date: 2022

The data produced in this study indicates that there are differences between the ICRI CSP comparator panels and TACM CSP comparator panels. Further, there are differences between taking direct measurements from known surfaces (i.e., the ICRI and TACM CSP panels) and obtaining indirect measurements from an epoxy putty casting of those same known surfaces. Therefore, it is important that the specifier indicate which method is to be used when qualitative or quantitative methods are invoked in the contract documents.

Correlation Studies between Outdoor Exposure and Accelerated Laboratory Corrosion Tests in Cold Alaskan Climate

Product Number: 51323-19384-SG

Atmospheric corrosion of metal alloys in cold environments is assumed to be negligible. However, studies in the Arctic and Antarctic regions have shown significant corrosion damage when exposed to cold conditions. While thermodynamically this is correct, other factors in such environments can be responsible for driving corrosion.

The subject wells are part of a project by San Francisco Public Utilities Commission (SFPUC) to
develop a groundwater supply in the South Westside Basin of San Francisco for use during
drought conditions for Daly City, San Bruno, and the South San Francisco District. The project
includes construction of 13 groundwater wells with a total capacity of 7.2 million gallons per day
(mgd). During routine maintenance inspection of two of the wells in Daly City, severe corrosion
was observed on the pump columns and on the stainless steel pump shaft.

Corrosion and Cracking Performance of Stainless Steels and Nickel Alloys in CCS Environments

Product Number: 51324-20962-SG

Carbon Capture and Storage (CCS) technology which involves capturing CO2 and injecting into geological formations is seen as a focus area for reducing CO2 emissions and sustainable future. One of the key challenges for CCS is material selection for construction of wells for injection and storage where the materials can be subjected to a complex environmental mix with various impurities present in the CO2 stream along with different phases within the well. Knowledge and understanding of corrosion and cracking performance of various materials in different environmental conditions relevant to CCS wells can provide a basis for material selection. Being a relatively new field there is an effort to build up knowledge base via testing, characterizing materials suitable for long term well service. In this study, martensitic, supermartensitic and super duplex stainless steels along with Age Hardenable (AH) Nickel Alloy were tested for both corrosion and cracking performance in different CCS type environments. The testing simulated exposure to injected fluid phase, interface between injected fluid and water phase and completely immersed in water phase. The details of testing performed results obtained along with discussions is presented so that it can provide guidance on material compatibility for some of the CCS environments.

The CARMA (Corrosion and Risk Modelling Analytics) project aims to provide improved corrosion prediction capability by using Machine Learning techniques. For the selected system, the initial CARMA model is trained by using a combination of online process monitoring data as the input, combined with online corrosion monitoring data as the output. Once trained and validated, the resulting model can then be used to predict corrosion rates in similar systems or in other parts of the same system, without the need to install corrosion monitoring devices or carry out routine physical inspections at the same frequency as in the past. This paper provides an overview of the model development process for one example system, incorporating data from both online monitoring in the plant and from laboratory experiments.

Corrosion Assessment and Repair for Aging Concrete Infrastructure

Product Number: 51324-20860-SG

Author: Stephen W. Foster; Terry McGovern

Publication Date: 2024

$40.00

An overview of various assessment techniques is discussed, including visual assessment as well as more detailed destructive and non-destructive assessment techniques, such as mechanical sounding, half-cell potential surveys, corrosion rate testing, material sampling, and laboratory analyses. Digital data collection techniques and the use of assessment data to develop service life and durability predictions based on the properties gathered by an in-situ assessment are also presented. Based upon the assessment results, the appropriate mitigation strategies can be selected. Several repair and mitigation strategies for reinforced concrete structures are discussed, along with the considerations involved with selecting each system with respect to cost, maintenance, and potential service life implications. Representative case studies will illustrate how these tools have been used for water and wastewater infrastructure.

Corrosion and formation of heavy deposit has been observed in firewater piping in carbon steel with stagnant seawater on several offshore platforms. This has resulted in plugging and constrictions in the pipes. Many offshore installations that have been operated for several decades in the North Sea are currently being sent for decommissioning. DNV has received pipe segment from some of these 20 to 40 years old installations for examination of the internal condition. The aim of this investigation is to gain knowledge based on operational experience in the North Sea. Two carbon steel pipes taken from the firewater ringmain on two offshore platforms from the Norwegian Continental Shelf (NCS) were examined. The objective of the investigation was to establish the internal condition, extent and nature of the deposits, determine mass of the deposit related to the observed metal loss and the dominating corrosion mechanism.
