Descripción del Curso:
5M-approach to control pipeline corrosion includes: Modeling, Mitigation, Monitoring, Maintenance and Management. These are described in the following paragraphs.

Modeling
Internal pitting corrosion is an important factor in degradation of oil and gas production pipelines. More than 50 models of pitting corrosion have been developed on the basis of corrosion science, electrochemical science, and corrosion engineering principles.  A method will be discussed to integrate unique features of several models into a single model that will be both scientifically sound and applicable in production applications.  A user-friendly software program SToPS (Systematic Treatment of Pitting Sequence) will be demonstrated.  This software can be used to determine critical locations for water accumulation, corrosivity of water, and probability of localized corrosion based on 15 readily available field parameters.

Mitigation
Inhibitors can be used to control internal pitting corrosion of production pipelines cost-effectively.  To select inhibitors and to decide on optimum concentrations, several laboratory experiments are usually performed.  Effects of several interacting parameters that may influence the simulation of field corrosion conditions in the laboratory will be discussed. Three ASTM standards, ASTM G170, G184, and G185, to evaluate the performance of corrosion inhibitors in the laboratory, were developed based on the R&D at CANMET. The Corrosion Inhibitor Selection Software (CISS) has been developed.

Monitoring
Many measurement techniques are available to investigate the corrosion performance and reliability of an operating pipeline, but each technique has its strengths and weaknesses. Usually more than one technique is used so that the weaknesses of one are compensated for by the strengths of another. The techniques that pipeline companies use to monitor internal pitting corrosion can be grouped into the following 6 categories: physical techniques; electrochemical techniques; non-intrusive techniques; on-line monitoring techniques; off-line monitoring techniques, and new techniques (e.g., fiber optics). Monitoring techniques will be reviewed and discussed at the Workshops.

Maintenance
The best practices in different parts of the world will be compared and contrasted with those in Canada and USA.  A review of the tools, methodologies, and considerations associated with the integration and management of pipeline integrity data will be conducted.

Management
Management involves people, money and data.  Change in production characteristics or operating practices, well re-completions and work-overs, lack of system operating history and practices, and changing personnel and field ownership may all lead to accelerated corrosion.

Who Should Attend:
This course is geared toward individuals at the technologist level who have some background in corrosion.
