A natural gas leakage was detected on the unpiggable high-pressure DN 600 pipeline Kasejovice – Mikulášov in Czech Republic after 50 years of operation. The pipeline was excavated and found to suffer from extensive corrosion; corrosion of a similar extent was also found when another section of the pipeline was excavated on the same location. The...

Enhanced Oil Recovery (EOR) technology with injection of carbon dioxide (CO2) in production oil fields become common method of oil recovery increase. From the first commercial CO2 EOR injection project on the Kelly-Snyder Field in West Texas past more than 45 years. However, there can be significant corrosion management challenges resulting from...

Simplification Improves Batch-tracking Accuracy in Pipeline with Slack Conditions

A “lean model” that minimizes uncertainties by simulating only the necessary characteristics for batch tracking proves to be more accurate than complex models that make a plethora of assumptions in attempting to model every single characteristic of pipelines with extreme elevation changes and slack. Energy supply chains require energy companies to...

Pipeline inspection using intelligent pigs is currently the safest and most reliable way to detect relevant defects, to plan repairs and maintenance and to calculate the pipeline lifetime. However, there are still many pipeline systems on- and offshore which were never designed and built for conventional ILI tools and modifications would be...
