Gas Hydrates, Wax and Asphaltenes II


Tavakkoli, M., ENNOVA LLC

Gas hydrates, wax and asphaltenes constitute the main elements of the challenges encountered in flow assurance. Asphaltenes is the heaviest and most polarizable fraction of the oil and is one of the major flow assurance problems that can occur at different stages of production. Asphaltene deposition may occur in the near wellbore region, production tubing, pipelines and processing equipment. The mechanisms by which asphaltenes precipitate and deposit have been subjects of research for several decades and although important progress has been made, many of the solutions that are tried in the field are case specific. Gas hydrates is a growing field of study due to its importance in oil/gas production, gas exploration from permafrost and oceanic environments, energy storage and transportation, and carbon sequestration.
