Challenges Inherent in the Development of Predictive Deposition Tools for Asphaltene Containing Hydrocarbon Fluids

摘要: Abstract The correlation and prediction of deposit formation are at the core flow assurance, risk assessment, other reservoir fluid management issues equally important for heavy oil or bitumen partitioning upgrading. Asphaltene deposition in particular is a key topic both sectors. Hydrocarbons from condensate-rich fluids to bitumen + diluent mixtures share constituents, asphaltenes resins pentane, can all be classified as asymmetric phase behavior perspective. dia-grams these characterized by zone four-phase surrounded three-phase two-phase regions pressure-composition constant temperature, pressure–temperature composition diagrams. Adherent asphaltenic solid liquid deposits only arise within some multiphase zones. Zones such SL1, SL1V, L1L2V, L1L2 prone production adherent particularly when combined with intermittent ...
