This article, written by JPT Technology Editor Judy Feder, contains highlights of paper OTC 29925, “Slug-Flow Root-Cause Analysis: A Data-Driven Approach,” by Anders T. Sandnes, Vidar Uglane, and Bjarne Grimstad, Solution Seeker, prepared for the 2019 Offshore Technology Conference Brasil, Rio de Janeiro, 29-31 October 2019. The paper has not been peer reviewed.

The complete paper discusses the successful application of a data-driven approach to analyze production data and identify root causes of slugging in a subsea production system on the Norwegian Continental Shelf. The approach used machine-learning techniques to model and analyze historical production data to identify the drivers behind slug flow. The results were used in combination with simulator studies and engineering experience to create a better understanding of the underlying root cause and to make it easier for field engineers to leverage all available information to reduce slugging and optimize production.
