From a risk assessment perspective, the material selection decisions for a new facility are paramount to the success of the project. The challenges in making these decisions are manifold and emanate from varied sources. Their relative importance may vary with each project but they all must be considered and assessed within the life-cycle time frame of the specific project.
Several disciplines are involved in the selection process and each may have different viewpoints, strong supporting information and may prioritise their risk assessments differently. The project manager must critically assess and rationalise the differing proposals and steer the project team towards some alignment in order to land on a robust path forward that best meets the project life cycle objectives.
This opening session of the workshop will focus on strategies to tackle these challenges as we move into more hostile and complex environments, and the risks associated with corrosion-related failures increase exponentially. Case histories will be presented to demonstrate the working process and the outcome.

The detection and measurement of corrosion is a major challenge for corrosion and integrity engineers due to the wide range of facilities in the system (vessels, pipelines, wells, etc.). Physical access to the locations of interest for monitoring is another hurdle in effective corrosion management. Corrosion monitoring of wells presents additional complexities in assessing internal and external corrosion in multiple, concentric strings of casing and tubing.
This session will discuss how new technologies and innovative adaptations of some old techniques is enabling a more reliable assessment of corrosion damage. The session will also address advancements in corrosion modelling and the use of data integration workflows to deliver realistic predictions and to develop a proactive approach to corrosion mitigation.

With increasing demand on energy sources there is a need for extending the life of mature producing fields. However, the surface and subsurface facilities in these fields have exceeded their original design life. The degradation mechanisms in these facilities are multiple and depend on the robustness of the original design, material of construction, operating conditions, maintenance practices, and the duration of service.
This session will discuss corrosion management strategies for such aging facilities to ensure that they continue to operate at the highest level of safety, integrity and efficiency while remaining cost-effective.

Tackling corrosion problems is always a challenging task and vital for maintaining the integrity of the process facilities, pipelines and wells. Selecting effective corrosion mitigation techniques requires a thorough understanding of the system, and particularly, the factors that influence corrosion. A proactive and dynamic approach is imperative in implementing corrosion mitigation strategies. Advancement inspection and monitoring help the corrosion experts in understanding the root cause(s) for corrosion and in designing appropriate mitigation techniques or strategies.
Various methods of mitigation techniques are in use in the industry including, but not limited to, material selection, coatings, chemical inhibition and cathodic protection. This session will provide insights into the latest technological advances in these techniques to enhance the overall effectiveness of the corrosion management activities.

Stand-alone non-metallic solutions such as glass reinforced epoxy and thermoplastics, and barrier solutions such as coatings and linings on carbon steel are gaining increasing acceptance in the upstream oil and gas systems as one form of corrosion mitigation measures. When chosen and maintained correctly, they work for and beyond the anticipated design period. On the other hand, being non-steel materials, they lack the strength of steel and many operators have concerns about their suitability originating from limited expertise available in material qualification processes for specific applications. This may result in an operator opting for a more costly, corrosion-resistant alloy even if non-metallic solutions prove to be a winner in life cycle costing analysis.
The session will discuss the perceived risks and concerns when considering such non-metals as well as successful implementation of such a solution by aligning the test basis to the field test results.

Many traditional corrosion monitoring and inspection methods including weight loss coupons, caliper surveys and intelligent pigs do not provide real time corrosion rate data and only give the operator retrospective information. Corrosion monitoring techniques such as electrical resistance and linear polarisation resistance probes provide an instantaneous corrosion rate measurement. Leveraging the advances in hard wire and wireless real time data telemetry, these techniques can provide the operator with a powerful tool to receive corrosion monitoring data instantaneously so that any unacceptably high corrosion rates can be immediately identified and rectified promptly.
This session will discuss the application of real time corrosion monitoring systems in successfully mitigating corrosion in the upstream oil and gas production environment and its advantages over traditional corrosion management systems.
