Asphaltene is a component of crude oil that has been reported to cause severe problems during production and transportation of the oil from the reservoir. It is a solid component of the oil that has different structures and molecular makeup which makes it one of the most complex components of the oil. This research provides a detailed review of asphaltene properties, characteristics, and previous studies to construct a guideline to asphaltene and its impact on oil recovery. The research begins with an explanation of the main components of crude oil and their relation to asphaltene. The method by which asphaltene is quantified in the crude oil is then explained. Due to its different structures, asphaltene has been modeled using different models all of which are then discussed. All chemical analysis methods that have been used to characterize and study asphaltene are then mentioned and the most commonly used method is shown. Asphaltene will pass through several phases in the reservoir beginning from its stability phase up to its deposition in the pores, wellbore, and facilities. All these phases are explained, and the reason they may occur is mentioned. Following this, the methods by which asphaltene can damage oil recovery are presented. Asphaltene rheology and flow mechanism in the reservoir are then explained in detail including asphaltene onset pressure determination and significance and the use of micro-and nanofluidics to model asphaltene. Finally, the mathematical models, previous laboratory, and oilfield studies conducted to evaluate asphaltene are discussed. This research will help increase the understanding of asphaltene and provide a guideline to properly study and model asphaltene in future studies.

“…The majority of the techniques available for this analysis are based on chromatography. − The oldest method for maltene (deasphalted oil) analysis is ASTM D2007, which involves a system of two columns of clay and silica gel. Additionally, high-pressure liquid chromatography (HPLC) is used for maltene quantification. , Another commonly used method for SARA analysis is based on thin-layer chromatography analysis with flame ionization detection (TLC–FID) …”

“…SARA analysis has been the subject of a great number of studies because of repeatability and reproducibility issues. − , Different methods have been proposed, such as automated asphaltene determinator coupled with maltene separation, optical measurement of SARA fractions, maltene fractionation by flash chromatography, and improved HPLC techniques. , The new methods are based on the Iatroscan (TLC–FID) method or gravimetric separation followed by liquid chromatography systems. There are some limitations related to using an Iatroscan method, such as losses of the light component, which is a special concern when analyzing light- and medium-gravity oils, and challenges to differentiate between the resin and asphaltene fractions. , Although automated techniques for measuring the asphaltene content are fast, the kinetics of asphaltene precipitation and aggregation may pose an additional challenge, which, in turn, might affect the accuracy of its quantification.…”

One common method for describing crude oils according to their composition is by grouping their chemical compounds into four categories: saturates, aromatics, resins, and asphaltenes (SARA). SARA analysis is based on the different degrees of polarizability and polarity of each group (Rapid and Accurate SARA Analysis of Medium Gravity Crude OilsFanT.BuckleyJ. S. Fan, T. Buckley, J. S. Energy Fuels20021615711575). Most of the available chromatography techniques used for SARA analysis suffer from limitations, such as using large amounts of solvent or sample and yielding irreproducible results. The advantages of previously used methods are combined into a single system for maltene (containing saturates, aromatics, and resins) analysis to obtain less loss of volatile components and more reliable results as well as to use less crude oil sample and solvent. In our proposed method, the system is closed and the possibility of evaporation is much lower than in an open column. The testing time for maltene analysis reduced from 7 to 2 days, and the amount of solvent and sample decreased by 90% of that which is used in the ASTM D2007 method.

“…Although ELSD is highly sensitive, it does not have linear calibration curves 17 . Therefore, a transport-flame ionization detector, which can theoretically quantify TAG molecular species, has been used for the detection and quantification of TAG molecular species 18,19 . However, the use of commercial instruments leads to several problems; therefore, the transport-flame ionization detector is not widely applied.…”

INTRODUCTIONThe main component of lipids is triacylglycerol TAG . TAG comprises one glycerol molecule and three fatty acid molecules 1 . As many types of fatty acids exist in nature, the combination patterns of the three fatty acids are almost infinite. The idea taking account of the combination of three fatty acids in TAG is called TAG molecular species . Fats and oils consist of many TAG molecular species and the physical properties of each TAG molecular species are different. The physical properties of TAG molecular species significantly affect their emulsification properties during food processing 2 . Consequently, it is important to develop a method of quantifying the ratio of TAG molecular species in fats and oils for complete characterization.To date, many methods have been developed to quantify TAG molecular species in fats and oils. A gas chromatography-flame ionization detector GC-FID system 3, 4 is employed in the official method for quantifying TAG molecular
