How Cognite Data Fusion® enabled effective slug prediction

Aker BP used DataOps provided by Cognite, including Cognite Data Fusion®, to analyze thousands of live and historical time series for signs of slugging.

Monitor and prevent slugging effectively

Slugging is a major challenge for the oil and gas industry. This irregular flow of liquid and gas in pipelines can be difficult to monitor.

Aker BP’s oil fields, Alvheim and Volund, have experienced this typical trouble with slugging. Several factors can influence slugging and some of these are transient such as, opening wells or re-routing wells. This can lead to the restriction of production potential for third-party tie-backs.

One major challenge was to reproduce these issues with physical models in real time, as two seemingly similar conditions can result in different outcomes. Aker BP needed an effective way to monitor and prevent potential slugging.

Real-time, actionable insights supporting production maximization

With Cognite Data Fusion®, Aker BP was able to access thousands of live and historical time series, continuously analyzing them for pattern recognition and statistics.

This aggregated data is fed into machine learning models with self-learning algorithms that identify field behavior and correlation for an automatic predictive model generation. Finally, Aker BP was able to develop optimization models that can be auto-updated with data. They deliver real-time, actionable insight to production engineers, supporting production maximization.

Operators now have access to user-friendly decision support and algorithms that deliver early warning signs of imminent slugging. The Alvheim oil field saw a 1% increase in production, thanks to improved slug handling and prediction capabilities.
