SARA analysis (Saturates, Aromatics, Resins, Asphaltenes) is a method used to characterize the compositional fractions of crude oil. Understanding the SARA fractions helps predict the compatibility of crude oil with different diluents, which is crucial for safe and efficient pipeline transport, especially for heavy crude oils. Heavy crude oils have high viscosity and density, making them difficult to transport through pipelines without dilution. Diluents, typically light hydrocarbons like naphtha, condensate, or synthetic crude oil, are added to reduce the viscosity and density of the heavy crude. However, if the crude oil and diluent....
