New Methods Analyze Asphaltene Deposition and Fouling in Reservoirs

摘要

Asphaltene precipitation and deposition in production tubing and surface facilities are well-documented issues, and different methods are available to manage them. However, the problems that asphaltenes may cause in the reservoir, especially in the near-wellbore region, are much less understood. This project aimed to develop experimental procedures and modeling methods to establish whether impairment caused by asphaltene deposition in reservoirs is a real problem and to develop an understanding of the mechanisms by which asphaltene precipitates, alters wettability, and obstructs flow by potentially depositing in the formation.
