Flow Experiments on Concentrated Hydrate Slurries

Abstract

Abstract Natural gas hydrates have been proposed to capture associated gas produced from offshore marginal oil fields. To evaluate slurry based hydrate technology, the flow properties of both water-based and oil-based hydrate slurries were investigated for different hydrate concentrations. This paper summarizes the production of oil-based hydrate slurries and the flow experiments performed on these slurries. The flow experiments were carried out in laminar and turbulent flow in a high-pressure pipe viscometer in the hydrate laboratory at the Norwegian University of Science and Technology (NTNU).
