Facility with 25 experimental rigs used to study gas hydrates (hydrate inhibitors, hydrate stability, hydrate monitoring, application in hydrocarbon fluids including CO2, their role in subsurface storage)

Autoclave Reactors: 11 rigs for measuring hydrate phase equilibria, kinetics of hydrate formation/dissociation, and evaluation of kinetic hydrate inhibitors/anti-agglomerants

Rocking cells: 2 rigs for investigating hydrate phase equilibria and kinetics for various fluid systems

Glass micromodel set-ups: 2 rigs with pressure ratings of 1200 and 6000 psia, for visual observation of gas hydrate formation, dissociation and distribution at the microscale.
