Abstract

Gas hydrates are ice-like solids that may form blockage in crude oil flowlines while rheology is a powerful filed to elucidate flow properties. This research includes extensive experimental and theoretical study on the rheology of hydrate-in-oil slurries, focusing on (i) developing a high-pressure rheometer apparatus to enable a direct coupling between the apparent hydrate-in-oil slurry viscosity and the hydrate volume fraction, (ii) collecting rheology data of hydrate slurries with and without anti-agglomerants , and (iii) proposing a new predictive model for hydrate-in-oil slurries, which has valuable contributions to fundamental understanding of hydrate slurry rheology and plug risk assessment.
