Abstract
Nowadays is known that gas hydrate formation is the biggest problem faced by flow assurance engineers in offshore oil and gas production. Due to the fact that are solid substances that do not flow, they can totally block the pipes causing great economic losses to the oil and gas companies. Several investigations have been made to comprehend and mitigate hydrate formation but this phenomenon still continue to be responsible for the main flow assurance issues and deserves special consideration. In order to better understand the phenomenon of hydrate formation and dissociation the evaluation of the role performed by the different compounds presented in the crude oil can be investigated, since there are crude oils that have more or less tendency to form hydrates. In the presented work, a high pressure cell is used to analyze the rheology of gas hydrate formation from water-in-crude oil emulsions under the effect of gas condensate addition (saturates). The main results obtained are expressed through viscosity curves as a function of the experimental time.
