The concept of using physics-based models for corrosion monitoring is still new although corrosion monitoring by use of hardware coupons and probes is well recognized. This paper describes the application in downstream related to crude unit overhead and demonstrates how the monitoring concept can be used and its benefits.
Chemical treatment of reservoir fluids within the wellbore is essential for the control of associated corrosion and scale deposition. The Wafra Risk Assessment was developed with the Likelihood of Failure (LoF) based on historical corrosion well workover failures and the Consequence of Failure (CoF) directly tied to oil daily oil production.
This study is focused on description, discussion and analysis of the different technologies available against external corrosion in offshore export pipelines and its suitability for the Venezuelan pipeline offshore projects. Several anti-corrosive protective coatings and concrete weight coating were evaluated.
