181 Asphaltenes in Flow Assurance I

Wednesday, April 13, 2016: 1:30 PM - 3:00 PM
340A (Hilton Americas - Houston)

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. In this session authors from industry and academia will present the latest advances on the mechanistic understanding of asphaltene precipitation and deposition, tools for its prediction and developed mitigation strategies based on experimental data as well as field experience. By combining the fundamental understanding of this problem and the experience in the field we aim to provide the cost effective solutions that the industry requires nowadays.
