Seawater Injection Systems

As hydrocarbon reservoirs mature production rates could drop due to a decrease in the associated reservoir pressure. One solution is to use seawater injection to maintain reservoir pressure and seawater injection systems are a common and widespread tool for maintaining production rates or increasing them.

The Middle East Region is home to some of the biggest seawater injection systems in the world with even bigger ones being built. Therefore, understanding how such systems work, what the common integrity threats are and how they are efficiently and successfully mitigated is of paramount importance.

Simultaneously, corrosion management is a rather fresh, but very useful and efficient concept. Thus, corrosion management applications could be used to further improve the incumbent asset integrity management systems associated with any seawater injection system. The main benefits of such corrosion management applications within any seawater injection system are improving corrosion failure pre-emption capability (within the seawater injection system concerned) and optimizing the associated corrosion and integrity costs.

In summary, this training course begins with a general introduction of a typical seawater injection system and then reviews the encountered deterioration mechanisms, their detection, monitoring, assessment and mitigation. Finally, it introduces the corrosion management concept and describes how corrosion management applications could significantly improve corrosion control within any seawater injection system.

By the end of this training course, participants will learn to:

• Fully understand how a seawater injection system work
• Appreciate the main deterioration threats are for both the facility and the associated reservoir
• Develop the best mitigation methods are for each deterioration mechanism
• Appreciate the corrosion management concept and its applications in seawater injection systems
• Develop corrosion control matrices and corrosion key performance indicators for better corrosion control within seawater injection systems

Anybody within any seawater injections system or among its contractors who is associated with corrosion engineering, asset integrity management, corrosion management, inspections, chemical treatments, coating systems, microbial control, project engineering, asset management and repair and maintenance would greatly benefit from this training course.

This training course is suitable to a wide range of professionals but will greatly benefit:

• Corrosion & Integrity Engineers
• Production & Operation Engineers
• Inspection Engineers
• Repair & Maintenance Engineers
• Asset Project Engineers & Asset Managers
• Chemical Treatment Suppliers
• Corrosion Monitoring Systems Suppliers & Lab Technician

The teaching will be done via PowerPoint slides containing text, tables, plots, pictures, etc. The teaching will be interactive; that is, on a regular basis the participants will be asked to participate in an ongoing topic, discussion or challenge. Team exercises will also be presented to the audience to take part. Past integrity case studies will be presented throughout the training course to promote best international practices while simultaneously discouraging integrity practices which had resulted in impairing asset integrity in various projects.

The seawater injection or the seawater treatment facility as a whole will gain a new knowledge and set of skills which will help it to significantly enhance its corrosion mitigation and control and further optimize its pertinent integrity costs.

The organization gains will include:

• Improved (site) personnel safety and environmental protection
• Enhanced teamwork, communication and reporting
• Increased corrosion failure pre-emption capability across the organization
• Optimised corrosion and integrity costs
• Improved chemical treatment, bacterial monitoring and control
• Increased production/operation times and reduced number of unplanned shutdowns

Participants will learn to mitigate and control corrosion more efficiently through improved understanding of premier root causes behind the majority of corrosion issues and failures. Attending the course will help them to:

• Learn how each different section of a typical seawater injection system functions
• Learn what deterioration mechanisms are associated with different sections and the reservoir itself.
• Better appreciate the MIC threat and its enhanced monitoring, assessment and mitigation
• Appreciate what the corrosion management concept its and how it is implemented
• How corrosion management applications improve corrosion control within a typical seawater injection system
