Resumo:
Natural gas hydrates are solid crystalline, similar to the ice, formed by the association of water molecules and gas of a given organized structure. Its occurrence is an undeniable concern for Oil and Gas, given the potential risk of flow assurance and may cause unscheduled downtime in operations, such as drilling and production. Therefore, large investments are made in order to prevent the formation of hydrates. However, the increasingly challenging scenarios of oil production are encouraging the pursuit of new methodologies for risk assessment, seeking to identify the conditions hydrates will form, but with little chance of clogging. In this context, the understanding of rheology of hydrate is a key element, it allows detecting the formation of hydrate as of changes in rheological properties. However, a difficulty of this approach occurs due to need for hydrate formation conditions, the combination of high pressure and low temperature. This work fits in this context: to evaluate the process of hydrate formation on conditions more favorable is used usually a fluid model that form hydrates at atmospheric pressure. This work aims to analyze the effects of the water cuts and surfactants on viscosity, in storage and dissipation modules of model fluid water emulsion in oil. The hydrate formation occurs adding on this model fluid cyclopentane.
