Abstract
The study of hydrate rheology is becoming increasingly important due to the constant expansion of the oil and natural gas industries in deeper waters. The hydrate formation process in the oil and gas sector is a big concern mainly because, in many cases, it ends up generating the blockage of pipelines, which leads to the production interruption, causing safety problems, and loss of time and money. Hydrates are crystal compounds formed by water and small gas molecules at typical thermodynamic conditions of high pressure and low temperature. In order to study the hydrates phenomenon, chemical compounds that induces their formation at atmospheric pressure are used, such as cyclopentane (CP) and tetrahydrofuran (THF). In this study, an emulsion formed from CP, Primol oil, deionized water, and Span 80 as a stabilizer agent is employed. The results aim to analyze the effect of several parameters on hydrate formation, such as: subcooling, shear rate, water volume fraction and the pre-treatment temperature.
