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.
