In ocean conditions of low temperature and high pressure, gas can be converted into hydrates, impacting the behavior of plumes from oil and gas blowouts. This study presented and evaluated formulations to parameterize the processes of formation, dissolution, and decomposition of hydrates implemented in a numerical model that simulates the fate of oil and gas releases in deepwater. Comparisons between the model results and available observations showed a good agreement. Numerical experiments were performed to understand the plume behavior with the presence of hydrates from blowouts at different depths. The analysis of the dynamics of the plume composed of water and gas showed that the hydrate formation increases the plume density and reduces its acceleration due to the buoyancy. As expected, the deeper the blowout, the greater the mass of hydrate in the plume and slower its displacement, spending more time to complete the disappearance of the hydrate. (AU)
