Flow assurance
The authors of this paper describe a project to develop a virtual sensor to monitor the cooling effect downstream of a subsea choke to avoid hydrate plugs during cold-start operations.
Subject-matter experts from industry and academia advanced distributed fiber-optic sensing technologies and their implementation in flow measurement during a special session.
This study investigates hydrate formation in a water-alternating-gas injection well under water-to-gas and gas-to-water changeover operations.

A newly developed superhydrophobic coating keeps offshore drilling pipes from being clogged by various substances. R&D Magazine recently recognized the coating and the unique process to apply it to pipes as one of the 100 most significant innovations of 2019. -
The papers presented here, including the additional reading papers on the potential novel applications of subsea tieback technology, focus on developing new analytical tools and new materials while providing safe, cost-effective, and reliable operations for flow assurance.

This paper describes a smart management system used for retrieving and evaluating all flow-assurance-related data for more than 700 of the operator’s onshore and offshore wells.
-
This paper describes a material designed to interact specifically with highly corroded and weathered pipe to enable in-place application and refurbishment.
-
This paper presents the results of an experimental and modeling study that demonstrates the existence of severe slugging in systems with upward-inclined lateral flow paths, such as a toe-down well.
