Abstract
One of the major problems currently encountered in offshore oil production is the obstruction of the transportation flow lines due to hydrates formation. Hydrates are water-based crystalline solids physically similar to ice, and are formed in the presence of water, gas and oil in conditions of high pressure and low temperatures. Hydrates formation is a critical issue that can lead to production downtime, which can yield economic losses to the companies and jeopardize the safety of production operations. Due to these facts, phenomena related to hydrates, as formation, dissociation, and forms to its mitigation have been studied for years by researchers. Aiming to contribute to these studies, this work presents a rheological analysis of ethane hydrates formed from water-in-oil emulsions. The measurements were performed in a Couette geometry inside a high-pressure cell of a rotational rheometer. The results are shown through viscosity curves as a function of temperature and time. Moreover, the gas consumed during its formation was determined employing the equation of state.
