Abstract
Asphaltenes are best known for clogging wells. flowlines, surface facilities and subsurface formations in the oil fields. Changes in pressure, temperature, composition and shear rate may cause asphaltene precipitation and deposition. These changes may be induced by a variety of processes, including primary depletion, injection of natural gas or carbon dioxide, acidizing treatments and commingled production of incompatible fluids. Asphaltene content is an important factor in determining the processing and refining paths of a crude oil, a convenient laboratory method has been developed to quantify the asphaltene fraction. This technique separates dead oil, or oil that has lost its gaseous components, into saturates, aromatics, resins, and asphaltenes (SARA) depending on their solubility and polarity.
