Abstract
This research investigates the flow assurance risks in production from natural gas hydrates, which have attracted interest as a
future energy resource, discussing the hydrate growth and rheology of hydrate slurries in pure water. The hydrate growth rate,
the infinite viscosity of hydrate slurries, the critical stress required for flow restart, and the hydrate particle size at the beginning
of shut-in were investigated in flowloop experiments. Mechanistic models, with empirical adjustments, and conceptual pictures
to predict/describe system behaviour were proposed and validated. These outcomes are key to understanding the process
leading to the hydrate blockage in water-dominant systems.
