Numerical Simulation on Sand Production Based on Laboratory Gas Hydrate Production Experiment

Journal of Marine Science and Engineering, 2023
Gas from natural gas hydrate (NGH) is priced competitively with gas prices. Most marine NGH is stored in low cementing strata, which easily cause sand production problems, restricting the commercial production and environmental safety of NGH’s ...

Gas Hydrate Gas Hydrate Equilibrium Measurement and Observation of Gas Hydrate Dissociation with/without a KHI

Procedia Engineering, 2016
AbstractThis paper presents new gas hydrate equilibrium data's for C2H6 (structure I) and CH4 + C3H8 (structure II) with and without the presence of sodium chloride. Macroscopic observation of gas hydrate dissociation under the presence of kinetic hydrate inhibitor (KHI) is also presented and compared with cells that have no inhibitor.
