... decrease. Micelles or early stages of precipitation of asphaltane improves oil mobility; however, further asphaltane aggregates can lead unfavorable results. Asphaltane is well known for its large molecular weight of 0.5-10 kDa in the crude oil. However, recently, molecular weight of asphaltene has...
