Course Credit: 0.15 CEU, 1.5 PDH

Asphaltenes are polar heteroatoms which are often found in varying amounts and properties in crude oils. They are usually dissolved in hydrocarbon mixtures. They may drop out due to changes in pressure, and composition, and temperature to a lesser degree. The precipitation and deposition in flow lines and in the production wells create problems. The deposition is often removed by aromatics such as xylenes. They can be also removed by functional molecules at much lower concentration. This presentation discusses the following items:

1. What are asphaltene molecules? How to describe phase behavior of asphaltenes in petroleum fluids.

2. Efficient dissolution of asphaltenes in functional molecules. Effect of water on asphaltene stability in crudes.

3. Efficient mitigation of asphaltene deposition in flowlines. Effect of water on asphaltene deposition and removal.

4. Reservoir simulation of asphaltene precipitation and deposition in the injection well, reservoir, and production well.

5. Opportunities in use of functional molecule in the wellbore.
