Integrated Experiments and Modelling for Hydrate Formation Management in Gas Condensate Systems via Novel Composite Materials Available to Purchase

In this work we present new experimental measurements of hydrate adhesion to a novel thermoplastic composite material using a micro-mechanical force apparatus. We find that the affinity of hydrates for such surfaces is at least 80% less than for steel pipelines, and that hydrate deposits do not anneal to the wall surface. These findings are used in conjunction with the UWA Gas Dominant Hydrate Extension for OLGA® to estimate the flow assurance implications for a long subsea tieback. Our simulations show that the injection of thermodynamic inhibitor may be halved, or eliminated entirely under some operational strategies.
