... heating; and dissociation in presence of viscous oil. This paper summarizes the experimental procedures and presents some findings of the second experimental campaign. Massive hydrate plugs of up to 200 kg were formed with high water to hydrate conversion rates. The plugs were characterized under...

... extent of liquid-gas separation. The geometry of those systems has a downward annular flow that can contribute not only for instabilities such as severe slugs, but also to an excessive gas fraction at pump intake, causing the phenomenon known as gas-lock. This study intends to characterize the fluid...
